The ladybirds I mean. I can't believe how many have colonised in my old wooden sash window-frames. They're not the cute little bugs that I remember from days of yore either, but aggressive little buggers who crawl over you when you're sleeping and nip you. So I've taken a can of Raid fly-killer to them. Are they like grey squirrels (another American import) in that they don't have any natural predators? I can't help thinking that if their numbers keep increasing at the rate of the last couple of years, then world domination is only a wing-beat away.
