I loathe them, really do. To say I am plagued with them is an understatement. They do not fly out of the windows as suggested. Each year have them literally covering walls on the back of the house, my neighbour couldn't believe it.
They are eating our native ladybirds, invasive species from Asia and carry a fungal/STD virus. Smell totally vile when picked up and this is why the birds not keen on eating them. They don't bite in my experience as picked up of loads and loads of them.
In the curtains, crawling up the bathroom and bedroom walls, in the curtains and even finding in the bedding. Honestly it's like something out of a horror film and yet neighbours don't seem to be bothered with them. So why me? Not nice at all and I love wildlife and nature but hate this smelly horrid infestions. Had workman in recently and he said never seen anything like it. They come out when a warm spell. We have sealed up everywhere they could come in but somehow to my amazement they still get in. Will have to take a picture next time the wall is covered and you will all see what I mean, its freaky.
