They've been there for years.

Sometimes I spray the area with soapy kitchen spray, day after day for a week. They can't fly through that mist and I end up with a pile of bodies on the ground below. But still they come back.

Fly spray and mosquito spray have little effect.

They aren't getting inside the house and don't appear to be going inside in the air-con pipe - but can't be sure about that.

Last year I used silicon sealant to cover up their nest, but they just build another one.

They seem to have a "race memory" that this is their home and this is where they'll stay.

They haven't bitten or stung me, so maybe I should just let them build their nest there.

Here's another video, with a bit of illumination:

The look like bees more than they do bees. If they are bees get them removed or you will have more and a giant honeycomb in the structure of your house.

These look like the ones that regularly built a nest in the electrical conduit at my gate, near to my bins.

It was where the cables from the meter went towards the house.

I just filled the space up with silicone.

You've got yourself a swarm of bees. It looks like they have a hive in there.

They look like native bees which depending on species can be sting-less and non aggressive.

I have the same 2 years. I tried everything, you can not eliminate them. They make me of the damage in the wood.

Try using a bleach solution in a spray bottle.

These aren't bees, these are ตัวแตน ตัวต่อ . More like hornets, and can sting so be careful. There are a few species in Thailand.

I used an aerosol of expanding foam once. Really worked! but the resultant mess, from over zealous spraying took quite a bit to clear away- because the stuff kept expanding like boiling porridge...

Next time we had a nest, I used an aerosol of 3M photo-tack spray. Kept reapplying it a bit each time through the day.

The bees filled the cavity with carcasses, and was messier than the expanding foam to clean up.

But, they never came back

Sorry Kenny I beg to differ. I suspect these are A. andreniformis dwarf honey bees.

Bee--ware

Yep, dwarf honey bees. There are several sizes and very persistent they are too!!! I had a tiny joint in a plastic door architrave and a very small version had a hive inside the hollow plastic molding & I got concerned about being stung so I filled the tiny joint with contact adhesive, adding more every time it dried. They have gone now from there but in the shower room, more have decided that the floor there or even near there with bare feet, because they land outside first before popping in for a drink. At one stage last dry season I started to affect the ozone layer over Thailand with bug spray. I just noticed the other day they are back again. Damn! Flip flops in the courtyard again!!!

They look more like small bees. Take rid of them anyway

Very useful bee type: their wax (kee tang nee), a very sticky glue, is [was traditionally] used in joinery work here is the north as filling for gaps and sometimes, when dry, as moulding for lacquer work.

Save the bees'(wax)..

Good Luck..

Aloha

The structure last year was bigger before I removed it and covered the mess with silicone sealant!

Yes, I think I may have to do the same again. I'll wait until it's dark and they aren't too active when I do it.

My window frame is aluminium, and last year they started to build another "nest" in a different spot about 4 feet away. But that was low enough for me to easily spray with various stuff and they didn't come back there.

I have that in the bathroom for stopping mould, but I found that ants and other creepy-crawlies - such as earwigs - aren't affected by it. Soapy kitchen cleaner seems to kill ants instantly.

I may spray with bleach before I cover with silicone sealant again.

The trouble is, it only takes a few with a good memory to come back and start building again.

Yes, whatever I do I have to keep killing them off every day until there are none left who remember where the nest was.

I had a bees nest in a compost heap in England many years ago that I had removed and had the area re-laid with fresh turf. For weeks after bees would come and hover over the spot where the compost heap used to be looking for their nest. Quite sad, really.

We had these under our roof for years, no harm done, nobody stung. Quite miss them since we sealed their nesting place off, not because of the bees but because we needed to finish the roof.
