Beekeeping chores for summer, autumn, winter, and spring
Starting your second season
Regardless of their precise location, honey bees are impacted by the general change of seasons. The seasonal calendar of events in Maine obviously looks different than one in Southern California. But different climates mean different schedules and activities for the hive and beekeeper. Knowing what major activities are taking place within the hive and what’s expected of you during these seasons is useful. For a good beekeeper, anticipation is the key to success.
This chapter contains a suggested schedule of seasonal activities for the beekeeper. However, you must note that geography, weather, climate, neighborhood, and even the type of bees influence the timing of these activities. The book is written from the viewpoint of a beekeeper experiencing a distinct change in seasons and climate (spring, summer, autumn, winter).
I also suggest some important tasks for the beekeeper and provide a rough estimate of the amount of time you’ll need to spend with your bees during each season. These time estimates are based on maintaining one to three hives.
Nectar flow usually reaches its peak during summer. That’s also when the population of the colony usually reaches its peak. When that’s the case, your colonies are quite self-sufficient, boiling with worker bees tirelessly collecting pollen, gathering nectar to convert into honey, and building beeswax comb to store both. Note, however, that the queen’s rate of egg laying drops during the late summer. And on hot and humid nights, you may see a huge curtain of bees hanging on the exterior of the hive. Don’t worry; they’re not running away. They’re simply cooling off on the front porch. It’s called bearding (see Figure 9-1).

Late in summer the colony’s growth begins to diminish. Drones still are around, but outside activity begins slowing down when the nectar flow slows. Bees seem to be restless and become protective of their honey.
Here are some activities you can expect to schedule between trips to the beach and hot-dog picnics:
You don’t do all that much until the end of the summer (the honey harvest) because your bees are doing almost all of the work! Figure on spending about eight to ten hours with your bees during the summer months. Most of this time involves harvesting and bottling honey (see Chapters 16 and 17 for more information on honey harvesting).
Most nectar and pollen sources become scarce as days become shorter and weather cools in autumn. All in all, as the season slows down, so do the activities within your hive: The queen’s egg-laying is dramatically reduced, drones begin to disappear from the hive, and hive populations drop significantly.
Your bees begin bringing in propolis, using it to chink up cracks in the hive that may leak the winter’s cold wind. The colony is hunkering down for the winter, so you must help your bees get ready.
When helping your bees prepare for the upcoming hardships of winter months, you must
Inspect your bees (look inside the hive) and make certain that the queen is there. As mentioned in Chapter 8, the easiest way to know you have a queen is when you find eggs. One egg per cell means the queen is present.
Be sure to look for eggs, not larvae. Finding eggs means that the queen was present within the last three days. Larvae, on the other hand, can be three to eight days old. Thus, merely finding larvae is no guarantee that you still have a queen.
When you wait too late during autumn, you discover that eggs and larvae are few and far between. In that case, actually finding the queen is the surest way to check. Be patient and look carefully.
Don’t underestimate the importance of ensuring the best possible nutrition for your bees. A strong, healthy hive is the bees’ best natural defense against pathogens and parasites. See Chapter 12 for more.
In cooler, northern climates in the USA, hives need about 60 pounds or more of honey as they head into winter. You’ll need less honey reserves (30 to 40 pounds) if your winters are short (or nonexistent).
Feed your colony. They’ll accept a 2-to-1 sugar-syrup feeding (see the “Autumn syrup recipe” sidebar) until colder weather contracts them into a tight cluster. At that point, temperatures are too cold for them to leave the cluster (see the “Clustering in a Winter Wonderland” section later in this chapter), so they are likely to ignore your offering.
The amount of honey needed for a Top Bar colony to survive winter depends on the climate where the colony is kept. In northern climates, a Top Bar colony can require about ten solid combs of honey, which is equivalent to about 60 pounds, depending on the width and depth of your particular hive. Another consideration is the depth of the honey band on each bar (see Figure 9-2). The honey band forms above the brood similar to what you find on a typical brood frame in a Langstroth box. Thin bands of honey on the brood comb can be a problem for the winter cluster since the winter cluster always starts on those bars. If a situation develops where the cluster is unable to break up and move to solid honey, the colony can starve with thin bands. If your honey bands are less than 2 inches wide on the brood bars, feeding your colony to increase the band’s width is important.
If you are using a Langstroth hive, place the inner cover on the top deep body, flat side down. The oval hole (if there is a hole) should be left open, and the ventilation notch cut into the ledge of the inner cover (if there is one) should be left open, too.
When you put the outer cover on a Langstroth hive, make sure you push it forward so the notch in the ledge of the inner cover remains open. Make sure the outer cover is put on the hive equidistant from side to side. The result is a gentle flow of air that carries off moisture from the underside of the inner cover and thus keeps the colony dry.
Top Bar hives generally do not need added ventilation but will benefit from added insulation. How much insulation you need is a matter of discovery based on the physical location of your apiary and your regional climate. One indication that insulation is required is excessive moisture on the hive sides and top and the face of the combs. During your inspections at the end of the season, be observant and note how moisture is building up.
Wrap the hive in a layer or two of black tar paper (the kind used by roofers; see Figure 9-2) if you’re in a climate where the winter gets below freezing for more than several weeks. Make sure you don’t cover the entrance or any upper ventilation holes. The black tar paper absorbs heat from the winter sun and helps the colony better regulate temperatures during cold spells. That reduces stress on the bees. The wrap also acts as a windbreak.
Place a rock on top of the outer cover to ensure that cold winds don’t lift the tar paper off (and the outer cover). I also cut a hole in the wrapping to accommodate the ventilation hole I drilled in the upper deep-hive body (see Figure 9-3).
Provide a windbreak if your winter weather is really harsh. Hopefully, you originally were able to locate your hives with a natural windbreak of shrubbery (see Chapter 3). But if not, you can erect a temporary windbreak of fence posts and burlap. Position it to block prevailing winter winds.
If you want a little extra protection for your Top Bar hive, a foam covering is an alternative to tar paper (see Figure 9-4). Foam provides your Top Bar hive with excellent insulation in addition to a windbreak. You can easily fabricate the panels from material purchased at a home center. The most important surface to insulate is the top of the bars because most heat is lost from the top. You can simply cut a thin, flat piece that fits inside your outer cover, and you’re done.

Alternatively, thick insulated wraps are available from bee vendors to better protect the colony from the cold. Sort of an insulated quilt for the girls.

Figure on spending three to five hours total to get your bees fed and bedded down for the winter months ahead.
A lot goes on inside the hive during the winter. The queen is surrounded by thousands of her workers — kept warm in the midst of the winter cluster. The winter cluster starts in the brood chamber when ambient temperatures reach 54 to 57 degrees (12 to 14 degrees Celsius). When cold weather comes, the cluster forms in the center of the two hive bodies. It covers the top bars of the frames in the lower chamber and extends over and beyond the bottom bars of the frames in the food chamber (see Figure 9-5).
Although the temperature outside may be freezing, the center of the winter cluster remains between 90 and 93 degrees (32 and 34 degrees Celsius). The bees generate heat by “shivering” their wing muscles.
No drones are in the hive during winter, but some worker brood begin appearing late in the winter. Meanwhile, the bees consume about 50 to 60 pounds of honey in the hive during winter months. They eat while they are in the cluster, moving around as a group whenever the temperature gets above 40 to 45 degrees (4 to 7 degrees Celsius). They can move to a new area of honey only when the weather is warm enough for them to break cluster.

FIGURE 9-5: Although the outside temperature may be freezing, the center of the winter cluster remains toasty warm. This cutaway illustration shows the winter cluster’s position.
Bees won’t defecate in the hive. Instead, they hold off until they can leave the hive on a nice, mild day when the temperature reaches 45 to 50 degrees (7 to 10 degrees Celsius) to take cleansing flights.
Winter is the slowest season of your beekeeping cycle. You’ve already prepared your colony for the kinds of weather that your part of the world typically experiences. So now is the time to do the following:
Make sure the bees have enough food! The late winter and early spring are especially hazardous because during this time colonies can die of starvation. Hopefully in the autumn you provided emergency food stores in the form of a pollen patty and sugar fondant.
Late in the winter, on a nice, mild day when there is no wind and bees are flying, take a quick peek inside your hive. It’s best not to remove any frames. Just have a look-see under the cover. Do you see bees? They still should be in a cluster in the upper deep. Are they okay?
If you don’t notice any sealed honey in the top frames, you may need to begin some emergency syrup feeding. But remember that once you start feeding, you cannot stop until the bees are bringing in their own pollen and nectar.
During this time, the bees are in their winter cluster, warm inside the hive. Figure on spending two to three hours repairing stored equipment, plus whatever time you may spend on bee-related hobbies — making candles, mead, cosmetics, and so on — or attending bee-club meetings. You might even decorate your hive for the holidays.
Spring is one of the busiest times of the year for bees (and beekeepers). It’s the season when new colonies are started and established colonies come back to life.
Days are getting longer and milder, and the established hive comes alive, exploding in population. The queen steadily lays more and more eggs, ultimately reaching her greatest rate of egg-laying. The drones begin reappearing, and hive activity starts hopping. The nectar and pollen begin coming into the hive thick and fast. The hive boils with activity.
Most of the information that follows applies to both Langstroth hives and Top Bar hives. I’ve included a separate section entitled “Managing Top Bar Hives in the Spring” at the end of this chapter that highlights a few differences.
Beekeepers face many chores in the springtime, evaluating the status of their colonies and helping their bees get into shape for summer months. Some of those chores include the following:
Conduct an early-bird inspection. Colonies should be given a quick inspection as early in the spring as possible. The exact timing depends on your location (earlier in warmer zones, later in colder zones).
You don’t need to wait until bees are flying freely every day nor until the signs of spring are visible (the appearance of buds and flowers). Do your first spring inspection on a sunny, mild day with no wind and a temperature close to 50 degrees (10 degrees Celsius).
A rule of thumb: If the weather is cold enough that you need a heavy overcoat, it’s too cold to inspect the bees.
Determine that your bees made it through the winter. Do you see the cluster? The clustered bees should be fairly high in the upper deep-hive body. If you don’t see them, can you hear the cluster? Tap the side of the hive, put your ear against it, and listen for a hum or buzzing.
If it appears that you’ve lost your bees, take the hive apart and clean out any dead bees. Reassemble it and order a package of bees as soon as possible. Don’t give up. We all lose our bees at one time or another.
Check to make sure you have a queen. If your hive has a live colony, look down between some of the frames. Do you see any brood? That’s a good sign that the queen is present. To get a better look, you may need to carefully remove a frame from the center of the top deep. Can you see any brood? Do you spot any eggs?
This inspection must be done quickly because you don’t want to leave the frame open to chilly air. If you don’t see any brood or eggs, your hive may be without a queen, and you should order a new queen as soon as possible, assuming, that is, the hive population is sufficient to incubate brood once the new queen arrives. What’s sufficient? The cluster of bees needs to be at least the size of a large grapefruit (hopefully larger). If you have fewer bees than that, you should plan to order a new package of bees (with queen).
Feed the colony. A few weeks before the first blossoms appear, you need to begin feeding your bees (regardless of whether they still have honey).
Feed the colony sugar syrup (see recipe in Chapter 6). This feeding stimulates the queen and encourages her to start laying eggs at a brisk rate. It also stimulates the worker bees’ wax glands. Continue feeding until you notice that the bees are bringing in their own food. You’ll know when you see nuggets of pollen on their legs.
Consider fortifying the syrup by adding one of the many natural food supplements that have come onto the market in recent years. Most contain essential oils. Some also contain vitamins, minerals, and amino acids to promote overall hive health, intestinal integrity, vitality and to stimulate brood production. For more on keeping your bees healthy, see Chapter 12.
Feed the colony pollen substitute, which helps strengthen your hive and stimulates egg-laying in the queen. Pollen substitute is available in a powdered mix or already formed into a ready-to-feed patty from your bee supplier. This feeding can cease when flight conditions improve and you see bees bringing in their own pollen.
Spring is just about the busiest time for the beekeeper. You can anticipate spending 8 to 12 hours tending to your bees.
You probably don’t need to medicate your bees during their first season (reputable bee suppliers should provide you with strong and healthy bees). Remember to play it safe and stop all medication treatments a couple of weeks before adding honey supers to the colony to prevent contamination of the honey that you want to harvest.
The list that follows contains a springtime medication regime that helps treat suspected diseases and control mites (see Chapters 11, 12, and 13 for more information):
Control varroa mites: There are a number of choices for treatment now in the market (see Chapter 13 for more information on varroa mite control). When using any of these products, it’s critically important that you follow package directions precisely.
Never, ever leave medicated mite control products in the hive longer than the directions state. Doing so exposes the mites to the active chemical ingredient, which becomes weaker and weaker over time. These sublethal doses increase the chance for mites to build up a resistance to these products. This tolerance is then passed on to future generations of mites, and subsequent treatments become less and less useful.
Control tracheal mites: When the weather starts getting warmer, you can place a prepared bag containing 1.8 ounces of menthol crystals on the top bars toward the rear of the hive (see Chapter 13 for more information). Set them on a small piece of aluminum foil to prevent the bees from chewing holes in the bag and carrying it away. Leave the bag in the hive for 14 consecutive days when the outdoor temperature ranges between 60 and 80 degrees (16 and 27 degrees Celsius).
Note that many consider the use of menthol a natural approach to dealing with tracheal mites. Menthol is an organic compound made synthetically or obtained from cornmint, peppermint, or other mint oils.
Adding a grease patty to the bottom board is another natural treatment for tracheal mites, although it is less popular now that it was a few years ago. Making grease patties is easy; see Chapter 13 for my favorite recipe. Use one patty per hive, replacing them as the bees consume them. Remove these patties when honey supers are on the hive. Unused patties can be stored in the freezer until you’re ready to use them.
Bees normally move upward in the Langstroth hive during the winter. In early spring, the upper deep is full of bees, new brood, and food. But the lower deep-hive body is mostly empty. You can help colony expansion by reversing the top and bottom deep-hive bodies (see Figure 9-6). Doing so also gives you an opportunity to clean the bottom board. Follow these steps:
Now you can see down into the lower deep that still rests on the bottom board.
It probably is empty, but even if some inhabitants are found, lift the lower deep off the bottom board and place it crossways on the inner cover that is covering the deep you previously removed.
This reversing procedure enables the bees to better distribute brood, honey, pollen, fresh nectar, and water. Reversing gives them more room to move upward, which is the direction they always want to move.
Repeat this reversal in about three to four weeks, restoring the hive to its original configuration. At that time you can add one or more honey supers above the two brood boxes — assuming the bees are now bringing in their own food and you have ceased feeding.

FIGURE 9-6: Reversing hive bodies in the spring helps to better distribute brood and food and speeds up the growth of your colony’s population.
After successfully wintering your Top Bar hive, the colony comes into early spring with vigor. The queen has been laying in small patches since early January, and the colony is prepared to build a large foraging population that will be ready when the main nectar flow starts. Make certain that the colony is “queen right” and the drive to reproduce (and later swarm) is monitored and managed.
One issue you will need to determine is the location of the cluster and its relative size. A Top Bar hive affords a quick and easy way to determine both without the need to open the colony and can be done quickly at any time of year. You simply remove the cover and slide your bare hand across the top bars, searching for a temperature change. As discussed earlier, the winter cluster, or for that matter any cluster, will be in the 90-degree (30-degree Celsius) range when actively rearing brood, and the bars directly over the cluster will be noticeably warmer.
Sensing the top-bar temperatures will enable you to outline the size and location of the cluster. Knowing where the cluster is will direct your inspections to that specific location and allow you to determine how to enter the colony without much disturbance of the bees. In a northern climate, an adequate spring cluster is five or six bars.
Your second-year colony will most likely initiate a reproductive swarm (Chapter 10 explains swarming). In a Top Bar hive, the swarm cells are likely to be located on the comb’s edge (see Figure 9-7).

FIGURE 9-7: When this newly forming swarm cell is capped, the colony will likely swarm. Notice the care the nurse bees are giving to the young larva.
So what to do about a Top Bar hive colony building swarm cells? One option is to have extra equipment on hand so you can split the colony in half by moving some frames of open brood to other equipment. The new colony will then raise a new queen. This should end the urge to swarm. Another option is to allow the colony to swarm with the intention to capture it yourself. But with this option you might miss capturing the swarm and lose your beautiful queen and, chances are, the colony will not make much honey that season. It’s your choice when it comes to swarm management. I suggest you experiment with both options and use this experience to learn more about the reproductive biology of bees.
Springtime is all about colony expansion. Your Top Bar hive will begin to build brood to meet the main nectar flow. With incoming nectar and pollen, your job will be to ensure that the brood nest has plenty of room to expand by supplying new bars as needed so you always have two to three empty top bars waiting for bee expansion. Observe what your colony is doing and insert either blank bars or more drawn comb from the previous season. If the colony feels it has run out of room to raise brood, it may decide to initiate a swarm.
This is not the bee-all and end-all of a to-do list! It’s simply a guideline to help you determine the kind of chores you should consider as the season progresses. The activities apply to both Langstroth and Top Bar hives. Note that a beekeeper’s calendar of activities will be different in Maine than in Southern California (see Figure 9-8). And the corresponding dates and activities can vary depending upon actual weather conditions, elevation, and so on. Consider this tool a “sanity check” as you and your bees progress through the seasons.
