I highly recommend Issaquah Pest Control. Our house backs to a greenbelt so we have lots of critters to deal with. Once we had an ant infestation in the house they came out and resolved it for us right away, and also dealt with our pesky moles. Since then they service our house quarterly and we've never had any issues. If we have any additional concerns they're always happy to take a look and address it right away, usually at no extra cost.
I like that they give a slight discount if you pay ahead for the year, and guarantee their work between service dates, so if something ever comes up in between visits they come out and address it. Scheduling is a breeze and they are highly responsive any time I have contacted them over email.
