Having a rat show up in your house is an unnerving and upsetting experience. After some investigation, including on Yelp, we chose CritterTech and we are SO GLAD we did. They are an amazing company in every way. They are totally professional; their knowledge of rats and rat behavior is impressive; they are punctual at every turn, and perhaps most important, they are thorough and thoroughly dedicated to ridding the house of the infestation. When one sees what they do, how they go about doing it, and the extensiveness of their efforts and concern, it is surprising how reasonable their fees are. The whole undertaking (of getting rid of the rat, sealing the house, and determining points of egress and ingress) cost far less than what we had imagined. We thoroughly recommend them.
