We've been using Karl and Dos Amigos Pest for years. Karl truly values service, he's friendly, personable, and takes great pride in his business and taking care of his customers. We have a monthly service and he's on the spot every month, every time. He's also very competitively priced and his products truly work to fend off those pesty Arizona scorpions! I highly recommend giving Karl and Dos Amigos a chance to earn your business. He won't disappoint.
