The simple sound of the word "cockroach" can make the skin of the strongest man crawl. Actually seeing one can send homeowners and apartment dwellers seeking refuge at the top of the highest piece of furniture or heading out for dinner to get away from the awful pests.

You may be able to stand one or two roaches around your garbage cans, for example, but not want to see a single one in your kitchen.
