Ok, after much googling, I think I have varied carpet beetles in my flat. I have become a woman possessed, pulling out furniture, hoovering, dettoling etc...... I've also contacted my managing agents about getting rid of a pigeon nest that is in the gutter above my bay window.
My problem is, I can't find a source of infestation, which is the first thing all the websites tell you to do. They are only in my living room and keep appearing on the wall near the window and on the windowsill. My living room has bare floorboards, which aren't sealed, and there is loft insulation (synthetic fibres) underneath - could they be breeding in that? If so, I'm fecked! Im hoping the bird's nest is the cuprit because my flat is full of nooks and crannies which are going to be difficult to completely clean. I haven't found any larvae, only adult bugs.
Any tips would be appreciated!
