There are many signs of cockroaches when they are active in an area. Typically these signs can be seen in teh form of dirt like specs that will accumulate in corners where they are hiding or living. The dirt is usually a dark brown, almost black, and very small, like the size of a poppy seed or smaller. Usually there will be a lot of these signs around in the corners of the cabinet up high or behind the door in the hinges. Set out one of our Roach Traps as seen in our Cockroach Control Article and it will catch any that are active which will let you know for sure if you can't find enough signs to confirm you do indeed have a problem. I would say this would be best before you start treating without knowing just what is leaving this mess around.

We get this question quite a bit. Clearly the spray provides immediate results but unless you do a lot of preparation to make all areas accessible, spraying is not nearly as effective in the long run. As a professional, I'm confident I can use the Drione and Orthene WP and knock them out but as a do-it-yourselfer, the challenge is much greater and we've learned people get great results using the roach gel. Since it's so much easier, cleaner and foolproof, I say go with this for now.
