We bought a home in Feb. 2013 that ended up having a severe mouse infestation (the previous homeowners hid it well, then left the country!). We called Pesticon based on Homestars reviews. The gentleman was there late on Sunday night to resolve the issue. He explained clearly what he was doing and provided us with many tips on how to manage the situation until it was resolved. He mentioned that the infestation was one of the worst he had seen but did not adjust the price he gave over the phone; he mentioned he used about four times the poison as he normally would. He promised that within 15 days, all mice would be dead. For the next few days I was disposing dead mice like crazy, and within about 10 days I think they were all dead. We have not seen a single mouse since, and it's now late October.
The service was perfect and I have since recommended them to friends for an ant problem and called them back to deal with a wasp's nest (I'll write a separate review for that call-out but it was 10/10). If I ever have any future pest issues, they will be getting my business. I highly recommend Pesticon!
