We moved outside of Toronto into a house surrounded by many trees. In the first spring we started having appearances of large ants in the kitchen which is when I discovered what carpenter ants are and the danger they present.
I found Orkin in HomeStars and decided to give them a chance. I signed up for the yearly service as we were also having a fair number of spiders throughout the house. They were very cooperative and flexible in the scheduling as I needed to coordinate a trip to the groomers for the cats so they'd be out of the house. It was a few back and forth phone calls and not once did I sense any frustration.
The technician educated me on carpenter ants and their sources. He pointed out which trees I needed to have pruned away from the house and we discussed the aged wooden deck in the back. After the spraying I took steps to have the trees pruned and we built a new composite deck - there hasn't been a carpenter ant since!
I'm very happy with the service of Orkin and would recommend them.
