I have had bees going through a smaal hole between two tiles just below the rook ( 2 story house). I am sure they are bumble bees. I am reluctant to do anything as they at the moment are not a problem. But as they are probably going into the loft and I may need to go in there if I need to get something or maintenance to the ball valve etc (maybe an emengency), I do not want to have a problem with the bees.
How long will the bees remain there.
If I block the hole from the outside (the hole is about 1 cm in dia.) how long will it be before any activity in the loft is stopped (the bees are all expired)
If I go in the loft with a light will the bees fly around annoyed as I had when we had a wasp nest 10 years ago.
I used to put Vapona in the loft every year till it stopped being on sale. Is there anything I can repel them in future, I have read reports of using math balls but they are frowned on these days.
I am quite happy to leave alone but dont want a problem when I go in the loft
Thanks for any replies
