Guys Just stumbled across a potential wasp hive going from the entrance shown in the picture. Seems like the overflow pipe hole, but I can't remember there been a pipe or not. Recently moved in so it's at the side of the house and never really go there. Should there be a overflow pipe? If there isn't, will it cause a problem? Also do I just cover the hole or get it seen to be pest control? I've got up in the loft and no visible signs of a hive so I'm guessing it will be in the cavity walls.
You can get a wasp killer spray - it fires a long jet of foam. If you are brave, you could try and squirt it in that hole - but be ready to run... Then block it with sealant or mortar. Your toilet will likely have a built-in overflow - it should appear as a trickle coming down the inside of the pan. If you have any concerns, lift the cistern lid and take a photo to post on here.
Have you seen the wasps, are you sure they are not masonry bees, easy to confuse the two. Overflow is built into the flush syphon. https://www.waspkilluk.co.uk/masonry-bees.html
One stings and flies away, and the other stings and - wait, I see a flaw in that test. Ok, ask your neighbour round and...
One is vague and fluttery and chust looks like wee barstewards, and the others are small and rounderer and cuter. Jesus - you don't know the difference? Look - just ask it how it voted - if it's 'Leave' it's a b******ing wasp.
A wasp's abdomen is black and yellow stripes and smooth whilst a bee has less well defined stripes, the abdomen is generally slightly furry and not so much black and yellow as off black and dark yellow. That is a very general distinction. The wasp's abdomen tends to be more pointy at the stingy end as well. If it's larger than normal with black and brown stripes that's probably a hornet.
Guys I zoomed into the pic, anyone tell me which bee this maybe? It's come inside the house now so if it continues will have to get pest control to remove them.
Bumble bee, quite similar to Bombus hypnorum, but there are many species of bumble bees, so could be wrong. But, if it is, your so lucky to have it. http://www.bwars.com/content/bombus-hypnorum-mapping-project
