What to do with a Dead Beehive

Everyone dreams of having healthy productive bees that produce tons of honey year after year. Alas, that is not always reality. In spite of your beekeeping skills, you will have some hives to perish. When a honey bee colony dies it is often called a “deadout”. Once it has happened, -now what- what do you do with a dead beehive?

Beehive Deadouts Happen

Finding a dead hive in your bee yard is never a good thing. It is especially disappointing for the new beekeeper who may have recently installed a new package of bees in the hive.

It is frustrating to lose a colony that never made it through the first season.

Unfortunately, it is common to lose hives occasionally in any apiary. Dead hives represent a loss of time and money.

Often our first response (or at least second – if you are a crier – like me) is – to question why this happened. We yearn for an explanation.

Could this have been prevented? Is it my fault the bees died? We do not always find all of the answers we are seeking but it is good to attempt a diagnosis.

Why Beekeepers Fail to Detect Dead Beehives Right Away

  • beekeepers fail to do hive inspections
  • colony failure takes place during Winter
  • activity noticed at hive entrance is robbers not residents

How does a beekeeper know that they have a dead beehive? This seems like a very simple question but the answer is more involved that you may think.

Good hive management requires routine hive inspections. You will be less likely to be surprised by the death of a colony if you perform periodic inspections during the warm season.

Another time of year when a failed colony may surprise you is during Winter. We don’t open hives very much during Winter or cold the temperatures of late Fall and very Early Spring.

If you are concerned about colony death during cold temps, this method may help reassure you. Place your ear against the back of the hive and give a firm tap on the hive wall – you should hear a brief buzz.

When beekeepers rely solely on bee activity at the front of the hive to gauge hive health, they may be very wrong. You may be seeing robber bees that are cleaning out the dead hive – rather than foraging members of the hive.

Taking the time to quietly walk by the hives can tell the beekeeper a lot about colony conditions. But to really know – yes you have to look inside.

When was the last time you inspected the hive that is dead? What were hive conditions? Check your beekeeping journal or notebook if needed.

Inspecting the Dead Beehive– Hive Autopsy

A dead out hive is one of the saddest things in beekeeping. It’s a feeling of disappointment, sadness and even a little guilt.

Don’t dwell on the negative aspects of losing a hive for too long. It is a part of beekeeping and often not something you could have prevented.

Take advantage of the opportunity to do a bit of diagnosis. If you see any obvious problems, perhaps you can use that information to save another hive in the future.

Sometimes, you will find dead bees inside the hive. Other-times, the box will be completely empty.

This does not necessarily mean that the bees have left or absconded. In the warm season, yellow jackets and other wasps will clean the dead bees out of a hive.

Where is the Cluster of Dead Bees?

It is common to find a cluster of dead bees that are head-first in the comb. Take note of where this cluster is located? If the colony has not been robbed out of food, do you see honey stored near the cluster?

A very small cluster of bees may die from being unable to generate enough heat for survival-even with honey close by.

A large cluster of bees may also die if honey is not within reach. The bees may not be able to leave the cluster to reach their honey stores due to extreme cold temperatures. Other times, they refuse to leave small patches of brood and everyone in the hive dies.

Inspect the Bottom Board

What do you see on the bottom board of the hive? Any signs of mice or mouse droppings? A colony will often abscond when mice move into their home.

Look closely through any dead bees at the bottom of the hive. Do you see dead varroa mites or deformed bees with bad wings? If so, your mite control program may have not be successful.

A strong colony with a massive mite infestation can appear healthy to outward appearances – until it suddenly crashes from a mite bomb.

Also, among the dead bees you may find Small Hive Beetles or their larvae. If beetles destroyed your hive, the combs will be full of beetle larva and slime. Beetles usually cause colony collapse during warm weather – later Summer into Fall.

Wax Moths Do Not Cause Dead Hives

Wax Moth larvae may be in the dead bees and hive debris. But please remember that Wax Moths are natures cleanup crew. In warm months, moths will move in – but they were not the cause of colony failure.

I often hear beekeepers say that wax moths killed their bees. No, they really did not. Wax moths fly into weak or dead beehives and lay eggs on the comb. Normal colonies evict the eggs or larva.

Weak colonies or dead hives with no protectors become a breeding ground for moths. The moth larva tunnel through the comb and leave behind webbing and feces (called frass).

The wax moths did not cause your dead bees. But why was the hive weak or empty to begin with?

Any Signs of Disease?

Most colonies do not die as a result of disease but it sure can happen. Often we don’t know why the colony failed – unless you send in samples for diagnosis.

The most serious disease to be concerned about is American Foul Brood. If you notice any dead brood in the hive that has symptoms related to AFB, ask for help from your stat extension service. This brood disease is deadly, uncurbable and spreads easily to other hives.

Equipment from diseased colonies should not be reused for new colonies and in most cases is destroyed.

How to Clean Out a Dead Beehive

The amount of work required by the beekeeper to clean a dead colony depends on the damage inside the hive. And, the possible cause of death. Any hive suspected of AFB should be destroyed.

However, when a dead hive (not believed to be diseased) is found quickly most of the honeycomb may still be in good shape. This is wonderful news and a chance to recoup some resources.

Storing Good Drawn Comb for Future Use

Remove any frames of comb that contain a lot of wax moth damage, etc. Tear out old dark comb (so black you cant see through) and replace by installing new wax foundation.

If you use plastic foundation, scrape off the destroyed comb, webbing and frass so the bees can start anew. There is no need to replace good wooden frames.

Bees invest a lot of energy into building comb. Good drawn comb is a rich resource for the colony.

Sheets of beeswax comb are vulnerable to attack by wax moths during the warm months if not protected. Freeze the frames for several days (to kill any pest eggs) and then store your boxes of drawn comb in either an airy shed or moth tight location.

Can You Harvest Honey from a Dead Hive?

In most cases, you can harvest honey from a dead hive. As long as the honey seems clean and fresh (not fermented), and you have not treated for mites (or other hive pests) with any chemical treatment that might be absorbed in the wax and honey.

Many beekeepers chose to “freeze frames of honey” and save the whole frames in the freezer . These can then be fed to a new colony of bees later on and serve as a big boost.

It is a good practice to keep a couple of frames of honey and pollen in the freezer if you have room. They will come in very handy later on-for you or the bees.

How to Clean the Bee Boxes of a Dead Beehive

After removing and storing valuable resources and removing all the webbing and trash in the hive, you are left with the wooden box.

Some beekeepers believe it is a good practice to wash the box in a light bleach solution. I’m not sure it helps but it shouldn’t hurt.

If the dead beehive has become a “hot mess” before you discovered it, you might see wax moth cocoons in the wooden ware. You can simply scrape them off and scorch the inside of the hive box with a torch if you wish.

Are Dead Hives Preventable?

Yes, sometimes deadouts are preventable if you find problems in the early stages. Routine hive inspections keep the beekeeper informed about the condition of the bees.

  • inspect hives regularly
  • check your queen status
  • monitor pest levels
  • feed when needed and check food stores routinely

Final Thoughts on What to Do With a Dead Beehive

It is important to understand that beekeeping involves colonies failing. And that is true today more than ever. Move quickly to protect any comb and other resources you may have inside the hive. The best thing to do with dead beehives is to try to analyze a possible cause and then save every resource possible for new bees..
