Question to all the hl pesties out there. I have a bumble bee nest in my loft space, its not somewhere i can access to deal with. I have seen them going in under the soffits to access the nest / hive whatever its called. they are bumble bees with a tiny white patch on the arse, never seen them before..... i can hear them in the loft space, almost sound like a nest of youn birds till you hit the ceiling then they are most certainly bees !!. do i need to get rid of them???, are they gonna cause any problems.what the f**k is the white arse patch variety ????................. or is it ok to leave
