When we purchased our home in Nov 07, it was a new construction that had been sitting vacant for a few months. Needless to say there were a few "unwanted crawling critters" in it. I contacted NW Pest and they sent out Ken and another guy to treat our home. The crickets and slugs were out of control but after 1 treatment they became practically non-existant. This spring when they came out to treat again the beetles that were getting in were still coming in after the 1st treatment. I called NW Pest up and they immediately sent someone out to respray,no questions asked. Haven't seen a bug since. Highly recommended!
