We thought we were dealing with a single (large) mouse under the sink and maybe something between the basement and main floor, but when our live trap didn't work, I turned to Homestars. Everyone seemed to recommend Chris Wright from "A Animal removal" - we called him, but he doesn't deal with rodents & recommended Kevin Diamond at GTA Wildlife Removal. Kevin was fabulous - professional, efficient, even compassionate towards the rodents he exterminates. He took the time to answer all our questions on the phone, including how he'd assess & deal with the problem, and how the treatment works. He came over that same day, and quickly identified by looking at the droppings under our kitchen sink that we weren't dealing with one mouse, but several rats (!), who had eaten through the wood and were making their home in the space above the basement. He checked out all our bathrooms, cupboards, attic (even though he explained that mice, not rats, go to attics), furnace room and garage. He left pellets in all the places he knows rodents like even if there was no evidence that they'd been there, all the time making sure that there was no way that children or pets would be able to get their hands on them. He showed me where to check under the kitchen sink to see if the rats were gobbling up fast enough to warrant his return prior to his standard 10-day "check up" post-treatment. Fortunately, the noises stopped within a couple days, and the problem appears to be over. Not a fun thing to deal with, but Kevin couldn't have made it easier under the circumstances.
