Absconding Bees- Why Bees Leave The Hive

Bees Absconding from the Hive

When all of the bees in a hive leave, we call this activity absconding bees. This is a sobering thing to happen to any one who keeps bees and it represents a significant loss. Bees that leave their hive in this fashion represent somewhat of a mystery. We don’t always understand why bees abscond but there are some common factors to consider.

Picture this – the beekeeper goes out to inspect a new hive. It is opened with high expectations to find – nothing. You are more than likely a victim of absconding bees.

All the bees are gone or at least most of them! A very few young bees and some pollen may be present- but for the most part the only thing left is comb and maybe some stored food.

Where are the thousands of worker bees that were present a few days ago? You had a fairly active hive and now its empty.

This happens more often than you may think and the upsetting experience can cause new beekeepers to leave the hobby.

Honestly, finding any empty hive doesn’t make us old beekeepers very happy either! But, we realize it is only one part of the beekeeping experience and better days will come.

How is Absconding Different from Swarming Bees?

In both absconding and swarming, some bees leave the home hive. However, the difference is the amount of the population that is suddenly gone and the continuation of the colony.

Almost everyone has seen pictures of swarming honey bees. Swarms are the way in which a honey bee colony reproduces itself and creates a new colony.

A swarm in transition may hang in a large ball of bees from a tree. If you are a beekeeper, perhaps you have been involved in catching a bee swarm or two.

Swarming activity is very different from absconding. In swarming, all of the bees to do not leave the hive.

In a hive that throws a swarm, roughly half the bees will stay in the old hive to carry on life in the mother hive. The swarm journeys to a new home to begin a new colony.

Swarming bees are splitting the hive into 2 parts and mainly happens in Spring and early Summer.

Absconding bees are leaving the hive completely (as a whole colony) to live somewhere else. Absconding bees can leave the hive anytime that the bees are active, even in the fall.

Why do Bees Leave the Hive?

Despite interacting with honey bees for thousands of years, we still do not know everything about them. The reason for bees leaving the hive often remains a mystery.

But, experienced beekeepers can recognize common conditions associated with absconding bees. While we can not control our bees, we do not want to do anything that adds to the problem.

Possible Causes of Bees Leaving Their Colony

Lets review some possible reasons for a honey bee colony to leave and abandon their home. Of course, we will probably never know for certain in each case – but these situations often accompany absconding bees.

  1. frequent disturbance from predators at night
  2. over anxious beekeepers opening the hive too much or being rough
  3. aggressive ant species in the bee yard
  4. very high level of hive pests
  5. bees are uncomfortable with hive
  6. poor ventilation
  7. bad beehive location
  8. bee genetics

Predators Disturbing Hives at Night

The colony may be under attack from predators – especially at night. Skunks and opossums eat honey bees. Though opossums are not thought to be a major threat and they do eat ticks.

Skunks will scratch at the hive entrance during the night. When bees come out to investigate, the skunk eats them.

This problem can be lessened by choosing a proper hive stand to raise the hive off the ground. 

If large predators are a problem in your area, perhaps you should consider putting some type of fencing around the bee yard. An electric bear fence can deter other types of predators too.

Opening Hives too Often

While it is important to  inspect your new colonies as needed- do not go into the hive every other day.

If you do, you may find the hive empty on your next visit. And, once the colony is doing well, you can reduce the frequency of inspections.

Aggressive Ants in the Bee Yard

Ants are attracted to beehives and cause considerable aggravation for new beekeepers. A small infestation of ants will aggravate the beekeeper more than the bee colony.

However in some areas, aggressive “fire ants” and other species (Argentine Ants) can invade the hive. This causes enough of a disturbance to create absconding bees.

I try to eliminate fire ants with a granular ant killer and inventive beekeepers come up with other ways to control common ants in beehives.

A High Level of Hive Pests Can Result in Absconding

Some of the absconding bee hives will be small, weak and unhealthy. These colonies were already under stress. Queen problems contribute to weak hives.

Infestations of varroa mites, hive beetles and other pests may make the bees decide to search for a better location.

Do you have a large population of yellow jacket wasps attacking your weak hives?  You can make your own trap or buy one! 

Most of this conditions on their own are not necessarily a big problem. But, all this stress contributes to unhappy bees.

Bees Leave The Hive Because They are Uncomfortable

I encourage beekeepers to paint bee hives with a good latex paint. Complete painting several days or weeks before bees arrive. A strong paint or wood odor causes some colonies to seek shelter elsewhere.

Wood smells, paint smells and don’t forget glue – all of these can be irritating to our odor sensitive honey bees. Give those new hive components time to air out.

Poor Ventilation Causes Problems for Bees

Bees do not like hives that are damp with poor ventilation. Too much humidity increases the chance of chalkbrood and other related diseases.

Sometimes we beekeepers try to keep our bees “too warm”. Hives need good ventilation. Bees must control internal hive temperatures to protect growing brood.

Poor Hive Locations Can Cause Absconding

The importance of a good hive location can not be overstressed. An area that is near food and water sources and protected from high winds is the goal.

Foragers need to be able to come and go without being disturbed by people, traffic or other things that annoy bees. They need to feel secure in their home.

Do Bee Genetics Promote Absconding?

As with everything in beekeeping, sometimes we cannot stop absconding bees. Some races are genetically predisposed to move to another location.

African honey bees often abscond relocating to a resource rich area. Most of the honey bees in the US have a degree of Africanized genetics. 

As a beekeeper, practice good management and be at peace with the fact that you have done all you can.

How to Keep Bees From Absconding

Whether you are a new beekeeper or one with years of experience, no one enjoys loosing a colony of bees. 

Here are a few tips that can guide you to lessen the chances of this happening in your bee yard.

  • choose a good hive location
  • elevate hives off the ground on a stand
  • place hives in sunny locations with good air flow
  • if predatory wasps attack your hives – place traps nearby
  • keep your colonies strong – good queen bee
  • control pests – mites
  • if lack of forage – feed your bees

Prevent New Hives from Absconding

It is most distressing when a new beekeeper loses bee colonies to absconding. To bring home a new package of bees and find them gone a couple of days later is very upsetting. 

When I purchase a new package of bees (yes I prefer packages over nucs), I take a frame with a little brood from a mature colony and give it to the new hive.

I believe this brood helps anchor the new colony to the hive. I have never had a new package colony abscond, so maybe it works.

I am not a fan of using queen excluders and other items to obstruct the hive entrance.  Drone bees cannot enter or leave the hive and young queens may slip through anyway.

Educate Yourself about Bee Behavior

While we will never know everything about honey bees and why they do what they do. Learning everything you can does help understand more of their behavior.

And if you invest the time to study bee nature, it will be helpful in diagnosing some hive issues.

Honey Bee Biology & Beekeeping is one of the best books in my beekeeping library. A good choice for a first or second year beekeeper who wants to learn more.

Final Thoughts on Absconding Bees

Honey bees are wild creatures that are beyond our absolute control.  If your bees leave the hive you provided for them, rest assured that they had a reason – even when we are left to wonder why?

Practice good beekeeping skills and understand that sometimes we have to let the bees be.

  1. Excellent explanation. Here in the Midlands we experienced a spike in abscondings last year around November – cause unknown. Thanks again Charlotte.

  2. Yes, I have heard about that strange behavior. I know we want to do this with everything but I still want to blame that end of summer thing on mites.

    Hi there I have a question for BeeKerper Charlotte.
    Where could I find a Bee School Association near Seneca SC. I would like to go to school for certification before I get my bees. Thank you.

  4. Oconee County has a Beekeepers Association. I suggest you contact the Clemson Extension Office in Oconee. They should be able to help.

  5. HI Charlotte,

    I am a new beekeeper. I started with 2 packs and am down to one hive. My question is, where can I buy another pack of bees for spring 2018. I have Carns, and really enjoy working with them.

  6. Hi Samantha, Sorry to hear that you have lost a hive. I hope you will be able to overwinter your remaining hive. I would watch the bees for sale ads that will come out in November/December. It depends somewhat on where you live. You can always order a nice carni queen later in the Spring and re-queen. Good luck to you.

    I so appreciate all of your publications to help us better understand what is happening with our bees and their colonies health and well-being. I have learned a lot from you and you publish in very down to earth language that anyone can read and follow. I could spend all day everyday just learning about our little buzzing friends and often find myself lead from one article to another to the point I’ve missed most of the day. Not a problem though because I am retired now and can take my time learning whenever and were ever I choose. Thanks a lot for all the help.

  12. Great information! I didn’t know there was a difference in absconding and swarming!!! Thanks Charlotte!!
