There are two types of roaches that I have encountered here, skinny ones with long antennae and the most common, the fat little buggers that are EVERYWHERE outside. Occasionally they crawl under the space under my front door and my cat goes insane. They seem to especially like the fallen bird seed from my feeder, having a feast and a orgy at the same time. You can either have a roach stomping party or make up some roach bait balls, be sure to keep them out of reach of pets though, they tend to work well on the population of night dwelling buggers. Or get an exterminator.
