My Pest control specialist Randall is very knowledgeable, and makes sure to give complete coverage. I can proudly say that I have never had an ant problem ever since I re-started service with Signature. I left once, because another company said that they could do the same thing for a cheaper price and they wouldn't have to come every month. What a big mistake!! Had ants, & spiders within a month. Their customer service was bad. I had to pay extra to get out of the contract. I ran back to Signature ASAP. Haven't had a problem since. Lesson learned...
