Help w/ pest control- esp cockroaches that come up through drains?

Answered
I use Home Defense for pest control, but I have actually seen roaches coming out of the bathroom sink drain. I try to keep the drains closed but the bathtub drain doesn't stay closed completely. I have rubber grip circles over the shower drains and have used straight bleach down the drains periodically.
