Re: @ Captain DaFt
Being American, I did a double take when I read that, as I read "mozzies" and thought for a moment you meant felines. That would be one hell of a nasty spider to take down a cat!
I'm not afraid of spiders per se, and quite like tarantulas, but I'd have to draw the line at seeing a furry 3" blur zipping across the room out of the corner of my eye, regardless of its ability to kill flies and mosquitoes. If insects that much of a problem, I'll be sure to keep my window screens in good repair rather than sharing my house with prowling spiders!
Come to think of it, can moggies share a house with huntsman spiders? It's bad enough when the cat tries to bring in a half eaten something it caught outside, but if it's catching them inside it'd probably bring a half eaten spider into my bed first thing in the morning. No thanks!
