Small Hive Beetle Horror

Small Hive Beetle (SHB) Control

So what do we do on the day we find small hive beetle scuttling about amongst our bees?

It seems that, with the exception of Portugal, whenever it has reached a new country it has managed to get itself well established before anybody notices it and once it is established there is no shifting it. Then we are looking at putting more pesticide strips into our hives and also ploughing up the surrounding soil and drenching it with chemicals which are currently illegal in Europe…

Surely the proactive thing is to ban all imports of bees before we get it because you know we can manage without Small Hive Beetle!

So get to know where your bees have come from.


Small hive beetles are easy to spot – apparently – running across the top bars of frames or scuttling across the floor so keep your eyes peeled. They will seek small spaces inaccessible to the bees so if you take a piece of corrugated plastic of cardboard and peel off one side then stick this – open face downwards – on the floorboard, you can make a simple beetle-harbour where beetles may seek refuge and be even more easily spotted.

As for the maggot – they can be mistaken for the larvae of greater wax moth but whereas wax moth larvae have 4 pairs of feeble little legs, the small hive beetle larvae have 3 pairs of more business-like legs and their bodies are equipped with several sets of spines. Also SHB larvae spin no webbing.

Infested honey has a wormy look to it and may be oozing slime.

If you find small hive beetle, or think you have found small hive beetle – contact Ministry of Agriculture immediately.


Some chemicals are available but are highly toxic and not very effective. On top of that they are almost certainly illegal here.

There are strips rather like the strips we know and love for Varroa. Coumaphos is effective against the beetles and strips can be placed inside the hive but of course your honey will almost certainly be compromised and the beetles will eventually become immune. The strips have to be cut in half and placed into a beetle harbour made of corrugated cardboard as mentioned above

Also, the beetles complete their life cycle in the soil so that needs to be turned over up to 6 foot from the hives and drenched with yet more chemicals. Permethrin is used in America but it is also extremely toxic to bees so cannot be sprayed on – instead it has to be watered in using a watering can or similar.

If you don’t want to use chemicals – you can try your hand at trapping.


In America various beetle traps are available – they mostly seem to consist of a reservoir of oil inside some sort of bee proof container with entrances for the beetles. Beetles will enter to seek refuge from the bees then fall into the oil and drown. Traps seem to catch a number of beetles but they will not eradicate the problem – they just help to keep the numbers down and may prevent a severe infestation.

Prevention is better than cure and good beekeeping practices are recommended.

Another wise method of prevention would be to ban the importation of bees – because that is how it will get here. Click here for more on that.

Good Beekeeping Practices
  • As with Varroa – keep colonies strong and also keep the levels of mites low to alleviate stress on the bees;
  • Weak colonies are vulnerable to attack so also keep a close eye on nucs and splits;
  • Don’t leave scrapings of wax and comb unprocessed – render as quickly as possible;
  • Don’t go flicking lumps of comb into the bushes either – it may attract SHB;
  • Keep hives in good clean condition – beetles can hide in cracks and crevices and may even be able to complete the life cycle in the garbage of a really filthy hive floor;
  • Keep a close guard on your honey house or wherever it is you do your extraction – stacks of supers are very attractive to beetles and they may lay eggs into them. Before or after extraction. If it’s before – there goes your honey harvest – it’ll be full of maggots and beetle slime;
  • Look for bees with hygienic traits and breed from these.

Above all – NEVER – import bees!
