Picking up some tricks of the trade
Considering really helpful accessories
Beekeepers use all kinds of fantastic tools, gadgets, and equipment. Quite frankly, part of the fun of beekeeping is putting your hive together and using the paraphernalia that goes with it. The makings for a beehive come in a kit form and are precut to make assembly a breeze. The work is neither difficult nor does it require too much skill. Some suppliers will even assemble the hive for you.
Many different kinds and sizes of beehives are available. Check Chapter 4 for the stats on several of the most popular hives for the backyard beekeeper. But worldwide, the most common is the eight- or ten-frame Langstroth hive. This so-called moveable-frame hive was the 1851 invention of Rev. Lorenzo L. Langstroth of Pennsylvania. Its design hasn’t changed much in the last 150 years, which is a testament to its practicality. Therefore, this is the style of hive that most of this book recommends. However, because of the increasing popularity of the Kenyan Top Bar hive, this edition includes supplemental information regarding it as well.
Here are some of the benefits of the Langstroth hive:
Woodenware refers to the various components that collectively make up the beehive. Traditionally these components are made of wood — thus the term — but some manufacturers offer synthetic versions of these same components (plastic, polystyrene, and so on). My personal preference: real wood. The bees accept it far more readily than synthetic versions. And the smell and feel of wood is ever so much more pleasurable to work with.
This section discusses, bottom to top, the various components of a modern ten-frame Langstroth beehive. As you read this section, refer to Figure 5-1 to see what the various parts look like and where they are located within the structure of the hive.
The entire hive sits on a hive stand. The best ones are made of cypress or cedar — woods that are highly resistant to rot. The stand is an important component of the hive because it elevates the hive off the ground, improving circulation and minimizing dampness. In addition, grass growing in front of the hive’s entrance can slow the bees’ ability to get in and out. The stand helps alleviate that problem by raising the hive above the grass. It also puts your hive at a more convenient height to inspect.
The bottom board is the thick bottom floor of the beehive. Like the hive stand, the best bottom boards are made of cypress or cedar wood. This part’s easy and intuitive to put together.

FIGURE 5-1: The basic components of a modern Langstroth hive.
When you order a bottom board, it should come with a notched wooden cleat. One way or the other, be sure to get an entrance reducer. Commercial versions come with notched wooden cleat. The cleat serves as your entrance reducer (see Figure 5-2), which limits bee access to the hive and controls ventilation and temperature during cooler months. The entrance reducer isn’t nailed into place, but rather is a friction-fit at the hive’s entrance. The small notch reduces the entrance of the hive to the width of a finger. The larger notch (if available on the model you purchase) opens the entrance to about four finger widths. And removing the entrance reducer completely opens the entrance fully.

FIGURE 5-2: This entrance reducer is being installed with its smallest opening providing limited access (for newly established hives and/or cold weather conditions).
Beekeepers use the entrance reducer only for newly established hives or during cold weather (see Chapter 6 for when and how to use an entrance reducer). This is the reason the entrance reducer isn’t shown in Figure 5-1. For established hives in warm weather, the entrance reducer isn’t used at all. The only exception may be when you’re dealing with a robbing situation — see Chapter 10.
The deep-hive body typically contains eight or ten frames of honeycomb (depending on the type/size of Langstroth hive you are using). The best quality frames have crisply cut dovetail joints for added strength. You’ll need two deep-hive bodies to stack one on top of the other, like a two-story condo. The bees use the lower deep as the nursery, or brood chamber, to raise thousands of baby bees. The bees use the upper deep as the pantry or food chamber, where they store most of the honey and pollen for their use.
The hive body assembles easily. It consists of four precut planks of wood that come together to form a simple box. Simply match up the four planks and hammer a single nail in the center of each of the four joints to keep the box square. Use a carpenter’s square to even things up before hammering in the remaining nails.
Place the hive body on the bottom board. If it rocks or wobbles a little, use some coarse sandpaper or a plane to remove any high spots. The hive body and bottom board need to fit solidly on the hive stand.
No matter what style of honey harvest you choose, a queen excluder is a basic piece of equipment that many backyard beekeepers use. It’s placed between the deep food chamber and the shallow (or medium) honey supers, that will added at the tops of the hive for bees to store their surplus honey. The queen excluder comes already assembled and consists of a wooden frame holding a grid of metal wire or a perforated sheet of plastic (see Figure 5-3). Plastic/metal varieties lack the wooden border. As the name implies, this gizmo prevents or excludes the queen from entering the honey super to lay her eggs. Why is the important? When a queen lays eggs in the super it encourages bees to bring pollen into the super, potentially spoiling the clarity of the honey you plan to harvest. The spacing of the grid is such that smaller worker bees can pass through to the honey supers and fill them only with honey.

FIGURE 5-3: A queen excluder.
Many experienced beekeepers (myself included) will not use a queen excluder because doing so can slow down the bees’ progress in producing honey. Some say it may even contribute to swarming (see Chapter 10 for more on swarming). However, it takes a season or two of experience to judge when it’s okay to bypass using a queen excluder (you can choose not to use the excluder if you are certain that there is a very strong nectar flow and the bees are rapidly filling many cells with nectar). My recommendation: Play it safe during your first two seasons and use the queen excluder. After that you can try not using it when you put the honey supers on, timed to coincide with a major nectar flow. By that time you’ll know what to look for.
Beekeepers use honey supers to collect surplus honey. That’s your honey — the honey that you can harvest from your bees. You need to leave the honey in the deep-hive body for the bees. Supers are identical in design to the deep-hive bodies — and assemble in a similar manner — but the depth of the supers is shallower.
They come in two popular sizes: shallow and medium. The shallow supers are 5 by 5 inches deep, and the medium supers are 6
inches deep.
Honey supers are put on the hive about eight weeks after you first install your bees. For the second-year beekeeper, honey supers are placed on the hive when several different spring flowers start to bloom.
The reduced depth of the supers makes them easy to handle during the honey harvest. A shallow super with ten frames full of honey will weigh a hefty (but manageable) 35 to 40 pounds. A medium super with ten frames full of honey weighs about 50 to 55 pounds; however, a deep-hive body full of honey weighs a backbreaking 80 pounds or more. That’s more weight than you’d want to deal with!
Frames are “action-central” in the beehive. Bees build their beeswax comb within frames. Frames are made of wood or plastic, with wooden frames being the most widely available variety, so here I will focus on the wooden type. A wooden- frame holds a single sheet of beeswax foundation (described in the next section). The frame is kind of like a picture frame. It firmly holds the wax comb that the bees build from the foundation template and enables you to remove these panels of honeycomb for inspection or honey extraction. Beeswax comb is too delicate to handle, but you can manage the frame holding the comb rather easily. Ten deep frames are used in each deep-hive body (unless you have decided on using an eight-frame version of the Langstroth hive). Frames are the trickiest pieces of equipment you’ll have to assemble. Beekeeping suppliers usually sell frames in packages of ten, with hardware included. All-in-one plastic molded frames with foundation require no assembly.
Although plastic frames and foundation are available from some beekeeping suppliers, I don’t like the plastic foundation. I much prefer the all-natural wax foundation, and I feel the bees share my preference. There is no doubt that plastic foundation is far more durable than delicate wax foundation, but a sometimes serious downside with plastic foundation is that the bees are very slow to work plastic foundation into honeycomb. You need a strong nectar flow to entice them. Not so with beeswax foundation. Want to be convinced? Use plastic foundation in one hive and pure beeswax foundation in a second hive. See for yourself which one is the winner.
Wooden frames come in three basic sizes: deep, shallow, and medium — corresponding to deep-hive bodies and shallow or medium honey supers. The method for assembling deep, shallow, or medium frames is identical regardless of its size. Each frame has four basic components: one top bar with a wedge (the wedge holds the foundation in place), one bottom bar assembly (consisting of either two rails or a single bar with a slot running its length), and two sidebars (see Figure 5-4). Frames typically are supplied with the necessary and correct size nails.
Courtesy of Howland Blackiston
FIGURE 5-4: The parts of a standard frame design.
Assuming you are using the traditional design that is so readily available, assemble your frames by following these directions:
Take the top bar and snap out the wedge strip.
You can use your hive tool to pry the wedge strip from its place. Clean up any filigree (rough edges) by scraping the wood with your hive tool. Save the wedge for use when you’re installing the wax foundation (see the “Foundation” section next).
Now snap your bottom bar assembly into the slots at the narrow end of the side pieces.
Depending on the manufacturer, this assembly will either consist of two rails or a single bar with a slot running its length.
Now nail all four pieces together.
Use a total of six nails per frame (two for each end of the top bar and one at each end of the bottom bar). In addition to nailing, I suggest you also glue the parts together using an all-weather wood glue. Doing so adds strength.
Repeat these steps until all your frames are assembled.
Time for a break while the glue dries.
Foundation consists of thin, rectangular sheets that are used to urge your bees to draw even and uniform honeycombs. It comes in two forms: plastic and beeswax. Using plastic foundation has some advantages because it’s stronger than wax and resists wax moth infestations. But the bees are slow to accept plastic, and I don’t recommend it for the new beekeeper. Instead, purchase foundation made from pure beeswax. The bees will accept it much more quickly than plastic, and you will have a much more productive and enjoyable first season with your bees. In subsequent seasons you can experiment with plastic — but I’ll bet you come back to the wax!
Beeswax foundation is imprinted with a hexagonal cell pattern on the wax that guides the bees as they draw out uniform, even combs. Some foundation comes with wire embedded into the foundation (my preference). Some you must wire manually after installing the foundation in the frames. That’s a lot of extra work and takes a bit of skill. I suggest using the prewired foundation.
Your bees find the sweet smell of beeswax foundation irresistible and quickly draw out each sheet into thousands of beautiful, uniform cells on each side where they can store their food, raise brood, and collect honey for you! Once they have finished this task, the comb is now referred to as drawn comb.
Like frames, foundation comes in deep, shallow, and medium sizes — deep for the deep-hive bodies, shallow for the shallow supers, and medium for the medium supers. You insert the foundation into the frames the same way for all of them.
Here’s how to insert foundation into your frames:

FIGURE 5-7: With the frame still upside down, use a brad driver to nail the wedge strip back in place.

FIGURE 5-8: Insert support pins in predrilled holes of the side bars to hold the wax foundation in place.
Finally, turn the frame as it will hang vertically in the hive box and shake it. If the foundation stays in place, you’ve got it right! You’ve completed building one frame. Now repeat — you have a bunch more to go!
The inner cover provides the correct “bee space” at the top of the hive while providing helpful ventilation. Wooden inner covers of good quality are made entirely of cypress or cedar wood. Budget models made from pressboard or Masonite also are available, but they don’t seem to last as long. Alternatively, there are durable plastic ones available that will never rot. See Figure 5-9. The basic design consists of a framed flat plank with a precut hole in the center of the plank. The inner cover resembles a shallow tray (with a hole in the center). In some models, a notch is cut out of one of the lengths of frame. This is a ventilation notch. I prefer this design for the extra ventilation it provides. The inner cover is placed on the hive with the “tray” side facing up. See Figure 5-10. If your model has a half-moon ventilation notch (as seen in the figure) place the notch toward the front of the hive.

FIGURE 5-9: A wooden and a plastic inner cover.
Look for cypress or cedar wood when buying an outer cover. These woods resist rot and last the longest. Outer covers assemble in a manner similar to the inner cover: a frame containing flat planks of wood. But the outer cover typically has a galvanized steel tray that fits on the top, protecting it from the elements. Alternatively, there are some plastic models on the market that will never rot. Not quite as pretty as wood, but perhaps more practical.

A Top Bar hive is basically a long box with sides that slope at approximately a 30-degree angle. Viewed from the end, the box appears as a trapezoid, wide at the top and narrow on the bottom (see Figure 5-11). This is where a Top Bar hive departs from the dimensional standards of a Langstroth box.
Courtesy of William Hesbach
FIGURE 5-11: The basic Top Bar hive box. Note the end is trapezoidal.
Top Bar hives are not standard and different manufacturers make different sizes. The lengths of Top Bar hives vary but are generally between 36 and 48 inches long. The depth of the box can also vary, but most Top Bar hives measure about 10 inches in depth. The Top Bar hive lends itself to home construction and with that comes your personal choice of size. See my book Building Beehives For Dummies (Wiley) for plans so that you can build your own.
As name implies, the key component of a top bar hive is the top bar. The top bar is a simple piece of 3/4-inch wood that spans the width of the hive, resting on the hive sides and is roughly 1⅜ inches wide. The lower surface of the top bar is used by the bees to attach their comb. The top bar is usually equipped with a center guide down the length of the bar that helps keep the comb straight as the bees build it. The center guides come in different designs based on the manufacturer, or you can choose your own style if you build your own top bars. The guides can be as simple as a piece of protruding wood (using popsicle sticks work well), or the bar may have a groove that runs the length of the bar. A strip of foundation can be securely waxed into the groove. See Figure 5-12.

FIGURE 5-12: The different types of center guides that help the bees get started building comb on the top bars.
Top Bar hives also use outer covers, entrance reducers, and hive stands, all designed for this type of hive; their functions are similar to the same items for a Langstroth hive. Find out more about these components in the earlier “Knowing the Basic Woodenware Parts of the Langstroth Hive” section.
Hive manufacturers traditionally make their woodenware out of pine, cypress, or cedar. Hardwoods are fine, but too expensive (and too heavy) for most hobbyists. Many suppliers offer various grades of components from a commercial budget-grade to a select best quality-grade. Go for the highest quality that your budget allows. Although the bees don’t care, some woodenware may be a little more expensive up front, but the higher quality parts assemble with greater ease and are more likely to outlast the budget versions.
Any of this stuff is available from beekeeping supply stores. Most of these vendors are now on the web. For a listing of some of my favorites, see Appendix A. And be sure to take advantage of the special discount coupons that are included at the end of this book.
Many suppliers offer a basic startup kit that takes the guesswork out of what you need to get. These kits often are priced to save a few bucks. Make certain your kit contains these basic items, discussed in this section:
Before your bees arrive, you need to order and assemble the components that will become their new home. You don’t need much space for putting the equipment together. A corner of the garage, basement, or even the kitchen will do just fine. A worktable is mighty handy, unless you like crawling around on the floor.
Get all your hive parts (woodenware) together and the instruction sheets that come with them. The only tool you must have is a hammer. But having the following also is mighty useful:
Feeders are used to supply sugar syrup to your bees when the nectar flow is minimal or nonexistent. They also provide a convenient way to administer nutritional food supplements for your bees. See Chapter 12 for more information on keeping your bees healthy.
New colonies need to be fed after installation. For established colonies, it’s good management practice to feed your bees in the early spring and once again in autumn (see Chapter 9). Each of the many different kinds of feeders has its pluses and minuses. I’ve included a brief description of the more popular varieties.
The hive-top feeder (sometimes called a Miller feeder after its inventor, C. C. Miller) is the model I urge you to use for your Langstroth hive (see Figure 5-13). There are various models and variations on the original design, but the principle is similar from one to the next. As a new beekeeper, you will love how easy and safe it is to use. The hive-top feeder sits directly on top of the upper deep brood box and under the outer cover (no inner cover is used when a hive-top feeder is in place). It has a reservoir that can hold one to three gallons of syrup. Bees enter the feeder from below by means of a screened access.

FIGURE 5-13: A hive-top feeder.
The hive-top feeder has several distinct advantages over other types of feeders:
But with all of these good features, there are some negatives:
The entrance feeder (sometimes called a Boardman feeder) is a popular device suggested in many traditional beekeeping books for Langstroth hives. It consists of a small inverted jar of syrup that sits in a contraption at the entrance to the hive (see Figure 5-14). Entrance feeders are inexpensive and simple to use, and they come with many hive kits for that reason. But I don’t recommend that you use an entrance feeder.
Courtesy of Howland Blackiston
FIGURE 5-14: An entrance feeder.
They have few advantages (other than being cheap) and have many worrisome disadvantages:
The pail feeder consists of a one-gallon plastic pail with a friction top closure. Several tiny holes are drilled in its top. The pail is filled with syrup, and the friction top is snapped into place. The pail then is inverted and placed over the center hole in the inner cover of a Langstroth hive (Figure 5-15). These work on the same principle as a water cooler where the liquid is held in by a vacuum. The syrup remains in the pail yet is available to the bees that feed by sticking their tongue through the small holes.
Courtesy of Howland Blackiston
FIGURE 5-15: Here’s a pail feeder placed over the oval hole of the inner cover. By covering the feeder with an empty deep-hive body and the hive cover/roof, you can keep raccoons out of the feeder.
Although inexpensive and relatively easy to use, it also has a few disadvantages:
Here’s yet another cost-effective solution (see Figure 5-16). Pour 3 quarts of prepared syrup into a one-gallon-size sealable plastic baggie. Zip it up. Lay the baggie of syrup flat and directly on the top bars. Note the air bubble that forms along the top of the bag. Use a razor blade to make a couple of 2-inch slits into the air bubble. Squeeze the bag slightly to allow some of the syrup to come through the slits (this helps the bees “discover” the syrup). Now you need to place an empty super and outer cover on the hive (to cover the feeder). This type of feeder works best on a Langstroth hive.

FIGURE 5-16: A baggie feeder is a cost-effective feeding option.
The advantages of using a baggie feeder are as follows:
There are some disadvantages:
This plastic feeder (often called a Boardman feeder) is a narrow vessel resembling a standard frame that is placed within the upper Langstroth hive body, replacing one of the frames next to the outside wall (see Figure 5-17). Filled with a pint or two of syrup, bees have direct access to it. But it isn’t very practical for the following reasons:
Courtesy of Howland Blackiston
FIGURE 5-17: Frame feeders are placed within the hive, replacing a frame of comb.
If you decide on a Top Bar hive, it will most likely come with plans to make a feeder or come with one you can just fill and use. Otherwise, Top Bar hive feeders fall into the category of in-hive feeders such as the baggie feeder, which is placed on the bottom of the box, not on the top bars as in the Langstroth hive, or the frame feeder mentioned previously. Other options include jars that fit inside trapezoidal-shaped containers, or simple plastic containers placed inside the hive and filled with syrup. See Figure 5-18.

FIGURE 5-18: Feeders for Top Bar hives come in different shapes and sizes.
Because there isn’t a booming commercial market for Top Bar hives, most Top Bar feeders wind up being homemade. You can find simple instructions on the Internet.
Two tools — the smoker and the hive tool — are musts for the beekeeper. They’re used every time you visit any kind of hive and are indispensable.
The smoker will become your best friend. Smoke changes the bees’ behavior and enables you to safely inspect your hive. Quite simply, the smoker is a fire chamber with bellows designed to produce lots of cool smoke. Figure out how to light it so it stays lit, and never overdo the smoking process. A little smoke goes a long way. (See Chapter 7 for more about how to use your smoker.)
Smokers come in all shapes, sizes, and price ranges, as shown in Figure 5-19. The style that you choose doesn’t really matter. The key to a good smoker is the quality of the bellows. Consider one fabricated from stainless steel to avoid rusting.

FIGURE 5-19: Various smokers.
The versatility of the simple hive tool is impressive. Don’t visit your hives without one! Use it to scrape wax and propolis off woodenware. Use it to loosen hive parts, open the hive, and manipulate frames. In addition, a frame lifter is used by many beekeepers to firmly grip a frame and remove the frame from the hive. Bee suppliers offer a wide range of styles and designs of hive tools to choose from. The ones pictured in Figure 5-20 are among the most commonly used.
Courtesy of Howland Blackiston
FIGURE 5-20: A frame lifter (top) and a hive tool (bottom).
At minimum, new beekeepers should wear a long-sleeved shirt when visiting the hive. Light colors are best — bees don’t like dark colors (black, navy, and so on). Wear long pants and slip-on boots. Tuck your pant legs into the boots. Alternatively, use Velcro or elastic strips (even rubber bands) to secure your pant legs closed. You don’t want a curious bee exploring up your leg! Better yet, order a bee suit (coveralls) or a bee jacket from your beekeeping supplier.
You should also invest in veils and gloves, which are discussed in this section.
Don’t ever visit your hive without wearing a veil. Although your new colony of bees is likely to be super gentle (especially during the first few weeks of the season), it defies common sense to put yourself at risk. As the colony grows and matures, you will be working with and among upwards of 60,000 bees.
Veils come in many different models (see Figure 5-21) and price ranges. Some are simple veils that slip over your head; others are integral to a pullover jacket or even a full coverall. Pick the style that appeals most to you. If your colony tends to be more aggressive, more protection is advised. But remember, the more that you wear, the hotter you’ll be during summer inspections.
Courtesy of Howland Blackiston
FIGURE 5-21: Protective clothing comes in various styles, from minimal to full coverage. This beekeeper uses a veil-and-jacket combination, leather gloves, and high boots to keep them bee-tight.
New beekeepers understandably like the idea of using gloves (see Figure 5-22), but I urge you not to use them for installing your bees or for routine inspections. You don’t really need them at those times, especially with a new colony or early in the season. Gloves only make you clumsier, especially for persons unaccustomed to using them. Importantly for bee care, gloves inhibit your sense of touch, which can result in your inadvertently injuring bees. Stings tell a story. Masking them is counterproductive and only makes bees more defensive when they see you coming.
Courtesy of Howland Blackiston
FIGURE 5-22: Although not needed for routine inspections, it’s a good idea to have a pair of protective gloves — and maybe even an extra pair for visitors.
The only times that you really need to use gloves are
Other times leave the gloves at home. If you must, you can use heavy gardening gloves, or special beekeeping gloves with long sleeves (available from beekeeping supply vendors).
All kinds of gadgets, gizmos, and doodads are available to the beekeeper. Some are more useful than others. I describe a few of my favorites in this section.
I have all my hives on elevated stands. Elevated hive stands are something you’re more likely to build than purchase. I’ve included detailed plans for making an elevated hive stand in Chapter 18. Alternatively, you can fashion an elevated stand from a few cinderblocks (see Figure 5-23). You can also use posts of various sorts (see Figure 5-24), or purchase a commercial-grade stand that’s waterproof and comes with a built-in frame rest (see Figure 5-25). In any case, having the hive off the ground means less bending over during inspections and makes the hive far easier to work with.

In the case of Top Bar hives, an elevated stand can be attached directly to the body to position your hive at a comfortable working height (see Figure 5-26) or fabricated to cradle the body of the hive and be more portable. Any stand that elevates the Top Bar hive to about 36 inches (typical countertop height) will work just fine.

FIGURE 5-26: This hive stand made from cinder blocks elevates a Top Bar hive to a comfortable working height and make inspections and harvesting less physically stressful for you.
For users of a Langstroth hive, a frame rest is a super-helpful device that I love. This gadget hangs on the side of the hive, providing a convenient and secure place to rest frames during routine inspections (see Figure 5-27). It holds up to three frames, giving you plenty of room in the hive to manipulate other frames without crushing bees.
The long, super-soft and washable bristles of a bee brush enable you to remove bees from frames and clothing without hurting them (see Figure 5-28). Some beekeepers use a goose feather for this purpose. Keep that in mind in the event you have an extra goose around the house.

FIGURE 5-28: Use a soft and washable bee brush to gently remove bees from frames and clothing.
You may want to sandwich a slatted rack between the Langstroth hive’s bottom board and lower deep-hive body (see Figure 5-29). It does an excellent job of helping air circulation throughout the hive. Also, no cold drafts reach the front of the hive, which in turn encourages the queen to lay eggs right to the front of the combs. More eggs mean more bees, stronger hives, and more honey for you! I use a slatted rack on all my hives.
The screened bottom board replaces the standard bottom board. Its bottom is completely open, with #8 hardware cloth screening replacing the wooden floor. Some commercial units include slots that hold a removable “sticky board” below the screen that you can use to monitor the colony’s varroa mite population. These products have become a standard part of integrated pest management (IPM) and are also available for Top Bar hives (see Figure 5-30).

FIGURE 5-29: Slatted racks help improve ventilation and can improve brood pattern.

FIGURE 5-30: Screen bottom boards are available for Top Bar hives.
There is another great advantage of using a screened bottom board — improved ventilation during the warmer months. Poor ventilation is one of the leading causes of stress on the colony. Using a screened bottom board (sans sticky board) provides the ultimate in ventilation.
I am often asked if you use a slatted rack with a screened bottom board. The answer is no. Use one or the other. Either one will improve ventilation, but only the screened bottom board will help you monitor the mite population.
It seems that whenever I get out in the yard and start an inspection, there’s something I need that I don’t have with me. I’ve pretty much solved that annoying situation by bringing along a toolbox with everything I might possibly need during an inspection. Here’s a list of some of the goodies in my beekeeping toolbox (see Figure 5-31):
