The flying ants have not returned
I used Positive Pest Management around 2 years ago for an infestation of flying ants in and around my basement and basement windows. They came promptly and on time and were very professional. Regarding prices, it's hard to say since they were the only company I called, but they seemed to be quite reasonable and certainly well within the range of what I expected to pay. Best of all, the flying ants have not returned.
