Extermitech came out to our home and sprayed our yard for Mosquito's. I have not seen one Mosquito since. They also sprayed Inside and Outside our home for Spiders. I haven't seen any of those either. I'm so glad that I could find someone to help us with the problems we were having. I have to say that they are Trustworthy, Affordable and Effective. I'm so glad we decided to go with Extermitech.
