I was about to decide that I had to forge a co-existence pact with the German Roaches (and other) that occupied my kitchen and master bath. Then I called Dennis at Alpha. It took only a day or so for the bait the put down to start to work. And from that point on, the bu population began to die off. Now--a couple of weeks later-- I'm not seeing any of the cruddy things. Dennis accomplished what another company didn't.
