The factory I work at would be a nightmare for you then, those bastards are EVERYWHERE. More often than not we get various species from all over the world that hide away in cardboard drums or wooden skids then mate/breed with the common roaches we have here. Its alot like the movie Arachnaphobia only with roaches.

Oh ya... Just avoid them most of the time.

They rarely annoy me.

Spiders here are small and harmless, so i quite like them for eating those annoying flies.
