So far the treatment is working very well. It has been several weeks and I have only seen 1 or 2 cockroaches every few days (as opposed to a dozen per day). I've noticed that they are no longer gathering in their regular places where they usually hang out either. It has only bee about 3 or 4 weeks since the first treatment so I am confident that as time goes on I will stop seeing them all together.

The guys who came to do the treatments were both very professional and knowledgeable. I felt completely comfortable with them being in my home exterminating the cockroaches.
