The OP probably has a rodent problem as well, roaches eat mouse poo so get rid of the mice and the roaches will be easier to eradicate.
Years ago, one of my office-mates at my company brought in a new computer he had just bought the previous week, to show off to all us nerdy types on our lunch hour. Apparently he had left it on during the weekend in his kitchen at home, because while he was proudly demonstrating some game on it, a roach crawled out and scurried across his desk. We all burst out laughing and making jokes about 'buggy' hardware. Next morning when I came in, he had spread 3 full cans of "Roach-Pruf" all around his desk, my desk, the carpeting, furniture, etc. Then that afternoon while I was making phone calls he let off an aerosol bug bomb in the middle of the room, necessitating immediate evacuation. Pretty hard to explain to the client why I had to hang up and run in the middle of our conversation...
All our boss did was wag his finger (fore, not middle) at my officemate and tell him not to do it again.. Sheesh..
