We had problems with ants and we started using Pratt Pest Management back in September. They've done wonderful as far as trying to figure out what the problem is and seeing what more they can do. Pratt Pest Management has very good customer service and is very knowledgeable. Their office staff is wonderful. Rocky, who always comes to our house, has been great! We are very happy with Pratt Pest Management. They have really stayed on top of it. We had silverfish as well but they have completely gone away!
