the old trick eh?
I do this all the time. Most recently to dispatch a large amount of wasps which had congregated in my kitchen one morning after the light had been left on all night. There were nine of the little bastards. Nine!
Anyway, I burst in there with a can of my girlfriend's hair spray, a yellow Clipper and a pair of sunglasses and sent all those stripey fuckers to hell.
Worked a treat.
