Now let’s discuss these major factors in detail.

 

 

Increase In Population Effect

Bee Overpopulation

Each bee colony has the maximum number of members in the fall. This makes the beehive too crowded to live peacefully. A large population needs a large space to live.

So, sometimes a portion of the colony members tend to depart from their old colony and try to build a new colony. This makes them defensive and aggressive.

 

 

Weather Effect

Most of the days in the fall, the weather is comparatively cold, below the suitable temperature for bees. This makes it difficult for the bees to maintain humidity inside the hive.

In order to maintain proper moisture inside the hive they need to waste more energy.

In simple words, fall is not the bee’s season, which drives them more anger.

 

 

Shortage Of Food

Due to the cold atmosphere in the Fall, a lot of flower plants are dying. Because of this reason, the number of food sources decreased. On the other hand, the number of pollinators in a colony increased.

Which creates a shortage of food supply for the members of the colony.

However, bees don’t solely depend on flowers. They try to collect food from different sources when there are no flowers.

That’s why you might sometimes see bees buzzing and swinging around any source of sugar like juice, sugar syrup, treacle, etc.

Change In Diet In the Fall

The pollinators prepare their queen and themselves for the winter. They usually eat only protein in the summer due to plenty of flowers available.

But in the autumn they changed their diet and started taking carbohydrates besides protein. A change in diet could change their instinct temporarily.

So, this could be a reason behind their aggressiveness.

 

 

Excessive Defensiveness Of Bees In Fall

Bees become more defensive to protect their food from being stolen by other bees from their neighbor’s colony.

As there is a food shortage in every colony. Bees try hard to collect food and meet the basic food needs of the colony. When they are unable to find flowers to collect nectar, some of the bees try to steal nectar from the nearest bee colony.

That’s why the worker bees are becoming more alert to protect their honey from stealing.

If they find any bees from other colonies, trying to steal honey from their colony, they will instantly sting and kill that bee. This is why you may see more dead bees on the ground during fall. 

As a result, all worker bees become alert during the season. So worker bees are busier than in other seasons. As a result, bees become more aggressive during the fall.

 

 

Human Behaviour

Human behavior in the fall also plays a vital role in why bees get very angry in this season. Here is which of your behaviors may drive bees crazy.

  • If you try to collect honey in the fall, it will even make it worse for them to survive.
  • If you inspect the hive very often it will make trouble for them to maintain moisture inside the hive.
  • Also, if you use pesticides inside and around the hive it will be more harmful to them.

 

As a result, they will be angrier, and the stinging instinct of bees will be much more in the fall.

 

 

 

Tips For Beekeepers To Deal With The Aggressive Bees In The Fall

As a beekeeper, you must try to calm your bees for a better and healthy bee colony. Here are several tips on how I handle my colony during fall when bees are very aggressive.

  1. Wear Protective Gear: Always wear a bee suit and cover your entire body each time you inspect the hive. Because in the fall season as they become aggressive they are more likely to sting you.
  2. Add Extra Feeder: This is the most important thing every beekeeper must do in the fall. That is to provide sufficient food for them. Place extra feeders inside the hive and add sugar syrup on a regular basis on those feeders.
  3. Inspect Less: Don’t open the beehive entrance very often. Try to inspect your beehive in the early noon of a sunny day. Select the right time for hive inspections.
  4. Don’t Extract Honey In The Fall: Never ever try to collect honey in the fall. Otherwise, your colony may be vanished due to a shortage of sucrose and protein.
  5. Split Crowded Hive: To deal with an overpopulated colony you can move a portion of the colony to a new hive. That is you can split an overpopulated beehive into 2 separate hives. 
  6. Don’t Use Too Much Smoke: During hive inspection, make sure to use the bee smoker properly. Don’t use smoke too much. Because too much smoke will make them very mad.
  7. Avoid Pesticides: Stop Using Bleach or any pesticide in any season around your hive.
