What homeowners in Brooklin, Port Whitby, Rolling Acres and downtown Whitby should watch for from spring through winter.
Quick Answer
Whitby’s mix of lakefront, creek corridors, conservation areas and newer subdivisions means pest problems change with the seasons. Ants and wasps peak in spring and summer, mice and rats move indoors in fall, and raccoons and squirrels look for attics and warm spaces from fall into spring. Bed bugs and cockroaches can show up any time of year. Catching the signs early makes treatment faster and cheaper.
Spring (March to May)
Ants
Carpenter ants become active as the ground warms, especially in homes near the lake and creeks where moisture is higher. Watch for large black ants indoors, winged ants near windows, or fine sawdust near wood trim.
Raccoons and squirrels raising young
Spring is when raccoons and squirrels have babies, often in attics, chimneys and under decks. Scratching or chirping in the attic or ceiling is a common sign. Removal has to account for young before any entry point is sealed.
Summer (June to August)
Wasps and hornets
Wasp nests grow quickly through summer and colonies get more defensive in July and August. Common spots in Whitby include soffits, sheds, decks, hedges and underground holes in lawns. Bald-faced hornets build large grey paper nests in trees and under eaves. Don’t spray or knock down a nest yourself — it can trigger mass stinging.
Skunks
Skunks dig under decks, porches and sheds in summer, and lawn digging is often the first sign. Sealing the openings after the skunk leaves keeps it from coming back.
Fall (September to November)
Mice
Fall is the busiest season for mice in Whitby. As temperatures drop, mice move in through small gaps around foundations, garage doors, utility lines and vents. Homes backing onto Lynde Shores, Heber Down and farmland near Brooklin often see more activity. Watch for droppings, scratching at night and chewed food packaging.
Rats
Rats also look for shelter in fall, often in garages, sheds and basements. Signs include larger droppings, gnaw marks and burrows near foundations or under decks.
Squirrels
Squirrels chew through soffits, roof vents and fascia to get into warm attics before winter. Chewed wiring in attics can be a fire risk, so don’t wait.
Winter (December to February)
Raccoons in attics
Raccoons look for warm denning spots in winter, especially in older homes with mature trees nearby. Heavy thumping at night, torn soffits or damaged roof vents are common signs. Humane one-way exclusion lets the animal leave but not return.
Mice that got in during fall
Mice that got in during fall keep breeding through winter. If you’re still hearing activity, it’s time for treatment plus sealing entry points.
All Year Round
Bed bugs
Bed bugs travel in luggage, used furniture and between units, so they can appear in any season. Look for small blood spots on sheets, shed skins along mattress seams, and itchy bites in a line.
Cockroaches
Cockroaches are most common in kitchens and bathrooms, and in multi-unit buildings and restaurants. Seeing them during the day or in more than one room usually means a larger problem.
Simple Prevention Tips for Whitby Homes
- Seal gaps around pipes, cables, vents and garage doors.
- Keep food and pet food in sealed containers.
- Keep firewood, compost and bins away from the house.
- Trim trees and shrubs back from the roofline and foundation.
- Fix leaks and moisture problems, which attract ants and other insects.
- Check the attic and soffits each fall for chew marks or damage.
When to Call a Professional
Call for help if you see signs in more than one area, if a nest is close to a doorway or high-traffic spot, if you hear animals in the attic or walls, or if a problem keeps coming back. Early treatment is usually faster and costs less.
