We get calls this time of year for American and Oriental cockroaches (aka Water Bugs) on the exterior or occasionally invading the interior. The things to know about these roaches is they are not a structure infester. People get them confused with the famous German cockroach that gets into the kitchens and likes to say hello to you when you turn on the lights at night.
The American and Oriental roach like the outdoors and really have no reason to be inside – they just end up there from time to time. The best way to avoid an overpopulation of these guys is to have your home treated earlier in the season. Generally, when you start to notice them, the population is already well established in your yard outside.
Remember, an ounce of prevention is worth a pound of cure.
