Masters Touch Pest Solutions was very responsive when I called about an ant problem I am having at our house. I decided to go with the yearly agreement since it was more practical. Two days after the bait was applied, I am still seeing ant activity but Masters Touch did explain that I will see that as the ants are carrying bait to their colonies. If I do not see an improvement in 2 weeks than they will come back out but they should be eradicated. I will know more about their service as they come out more next year but I have been happy with their customer service.
