Tree Bumble Bee Explosion

Published 28.May.2014, 10:49pm

Bombus Hypnorum

The Bumble bees you have in your eaves are probably Bombus hypnorum (tree bumble bee) as their population seem to have exploded this year.

Removing them is not an option as it would involve costly scaffolding + a builder to make good tiles etc.. any way bees have an excellent homing instinct and would keep returning to the same place The ones you can see flying in circles outside the entrance are drones waiting for the queen to emerge for them to mate with and they do not have a sting. They only have a very small nest size similar to the size of a birds nest and they will not do any damage to your roof space. They will occupy your roof for the next couple of months while they have their brood.

Bumble bees cannot be poisoned and in fact there is a substantial fine if they are poisoned. This is in place because the poison will get in their honey and will inevitably be robbed out by our honey bees and will then end up in the human food chain.

Live with them for the next couple of months and just be aware of their flight path, which will be mostly into other people’s gardens and do not bang doors nearby as they may be agitated by the vibration. You can leave windows open at night as they do not fly at night - if you want to leave window open during the day put net curtains or a screen if you want to avoid the odd stray entering by mistake.

Once they have gone it would be prudent to fill up their entry point to prevent another colony taking up residence either later this year or next.

Final thoughts

The bees are not going to harm you or your child, they have no reason to!

They do not damage the structure of your property. The only common factor is they occupy a small part of your house in which they are raising their young as well as pollinating plants which provide you with sustenance.

Killing them is not an option since the only pesticide licensed for killing bees is only available to professional operators and is restricted to Apis mellifera, used against any of the non stinging solitary bees 200 + types or 26 sorts of bumble bees would be contrary to the Control of Pesticides Act 1986. The Countryside & Wildlife Act.

Do remember when you instruct work to be done in Law you become the "Employer" which carries certain duties of care.

Hi, I have a small colony of bees in my loft space. They are not worrying me and I don't mind them being there (I shared my garage with a colony last year). Last night though I came home to find my kitchen and bathroom with lots of bluebottles! I have searched for anything "dead" which may have caused this, I have two cats. The flies seems to coming from the same area as the bees, is there a connection? The bees are directly above my bathroom.

Hi We have just noticed a few tree bees crawling behind the wood on our extension by our back door. Mainly they are small and then every now and again a very big one goes in. I am assuming this is the queen, they are the drones and she comes out to mate. This is really worrying for us as they are at head height right outside our back door into the garden. I am assuming the numbers are going to dramatically increase when the new bees hatch. Is there anything we can do now to prevent this as it will mean will will not be able to access our garden for a few months?
