I was so impressed with this company. The technician was so knowledgeable about this trade. He came in and without me saying anything knew exactly what type of problems I was having. He walked around and it hardly looked like he was doing anything, but my problem stopped before it had the chance to start. They recommend you stay out of the treated area for an hour. They have a 90 day warranty on the service, during which time you can call and have them come out to respray if you are still seeing pests. They call you after that and offer you a contract for them to come out periodically at a better rate. No pressure, just the offer. A great deal for a great service.
