Mosquito said:What exactly are you spraying them with?
What I use have given me something like these stats over the last year or so:
Code:Critter Kills Observed time til death Ants Thousands 0-5sec Roaches >100 1-5min Dogs* 4 2-10min Spiders 0 Still living after 3 days of grace, shoe-time!
And yes, I have sprayed quite a number of spiders. Given them an unhealthy dose, in fact. Just doesn't seem to do anything but piss them off (they get absolutely hyper for a while, then they just keep going on with their business as if nobody just emptied a large spray-can of industrial strength poison in their eyes.

*Well, not really, but I think it would work, should they keep trying to give me a heart attack. Self defence, I tell ya!
The one I've got at the moment is called 'the ant and crawling insect gun' manufactured by a company called 'Scotts'. It doesn't kill spiders immediately but I work on the assumption that they crawl off somewhere to die (I have seen ones that were dead a day later after getting a dose). Its not intended to kill immediately - it leaves a film of poison on the sprayed surface that the spiders etc... do not want to touch and its pretty effective at that. Sprayed in the usual spider haunts (corners of rooms, holes in bricks etc... it will keep them spider free for a good while.
