We had brown ants invasion that we could no longer handle, so I called Pest Pro, the guy who answered the call scheduled an inspection and the technician came the next day in the morning. He was very helpful and very professional. The ants were gone right after he left the house and I didn't even have issues with whatever chemical he used. It's almost 1 week now and I haven't seen any ants in our house. Thanks to Pest Pro.
