What we see in Bolton
Bolton sits in the Humber River valley beside open farmland, so carpenter ants and fall mice are the most common calls.
Activity rises as temperatures drop in fall and mice look for warm basements and garages. Nearby construction can also push rodents into finished homes.
German cockroaches spread between units through shared walls and plumbing, so apartments and townhouse rows often need neighbouring units treated too.
They travel in luggage, used furniture and shared laundry rooms. Common in rentals, basement units and multi-unit buildings.
Pavement ants march in each spring. Carpenter ants nest in damp or damaged wood around decks, windows and rooflines.
Wasp nests grow fastest in late summer under eaves and in sheds. Mosquitoes breed in standing water in yards, planters and eavestroughs.
