Great link thanks Beachdog, the prices are fantastic in comparison to what I would pay here, half as much more over here or more! Only problem is I'm in Scotland, and the links to the stores I've seen on this site so far don't ship out as far as here.
The flea powder is really my only option right now to get the buggers out of the carpet. I have a pet hoover, and I'm very particular about my hoovering, so he won't be breathing anything in. I'll be getting him out of the way too while everything is done. I also never use fragranced carpet powders. The way I see it is, yes I'm as paranoid as that, but there's just as much risk in my eyes from using a smoke bomb, and definitely from continued usage of a very powerful poison in pill form. Hence I asked for natural alternatives.
