Gta Toronto Pest Control

I have a fairly large house and the carpenter ants seem to come out from everywhere. a couple of years ago i hired a company and when i called back i was told that they are only responsible for 1 area. Last year i had Pestokill in and they took care of the entire house, they even came back when i called them about seeing ants at the far end of my lawn. I will surely call them back this year once the weather gets warmer because i don't want to take a chance with those ants or another company.
