Household pests are more than just an annoyance—they can damage property, spread harmful bacteria, and disrupt the comfort of your home. From tiny ants marching across the kitchen counter to cockroaches hiding in the dark corners, these uninvited guests often find ways to thrive where food, warmth, and shelter are available. For Scarborough homeowners, changing seasons make pest problems even more common, with insects and rodents seeking refuge indoors.
Most Common Household Pests
Ants
Ants are one of the most common household pests, often invading kitchens and pantries for food. In Scarborough, homeowners frequently encounter pavement and carpenter ants, which can become a serious nuisance if left unchecked. Pavement ants usually appear around cracks in driveways or along baseboards, while carpenter ants can cause structural damage by tunnelling through wood.
Early signs of an infestation include visible ant trails, small soil or wood shavings piles, and foraging ants in kitchens or bathrooms. To prevent ants, it’s important to keep food sealed, wipe down counters, and eliminate moisture sources that attract them. For light infestations, gel baits and non-toxic ant traps can be effective, but if ants continue to return—especially carpenter ants—calling an ant pest control is the safest way to protect your home.
Cockroaches
Cockroaches are among the most troublesome pests for Scarborough homeowners because they multiply quickly, spread bacteria, and trigger allergies. The two most common species found indoors are the German cockroach and the Oriental cockroach, which thrive in warm, moist areas like kitchens, bathrooms, and basements.
Signs of an infestation include foul odours, smear marks, egg cases, and nighttime sightings of fast-moving roaches when the lights are turned on. To manage cockroaches, sanitation is critical—keep food sealed, clean grease from stoves, and empty trash regularly. Gel baits and insect growth regulators are far more effective for control than sprays, as they target the colony instead of killing visible roaches. Severe infestations often require professional cockroach control treatment to eliminate hidden nests and prevent re-infestation.
Mice & Rats
Rodents are a year-round problem in Scarborough, especially as temperatures drop and they seek shelter indoors. Mice and rats can squeeze through tiny gaps around doors, windows, and utility lines, making homes an easy target. Once inside, they contaminate food, chew on wires, and leave droppings that pose health risks. Common signs of an infestation include scratching noises at night, gnaw marks on furniture or food packaging, and nests from shredded paper or fabric.
To prevent rodents, seal all entry points with steel wool or caulking, store food in airtight containers, and close garbage bins tightly. Snap traps and bait stations can reduce small infestations, but large or recurring problems often need professional rat control to ensure complete removal and long-term protection.
Bed Bugs
Bed bugs are a growing concern for Scarborough homeowners. They often hitchhike into houses through luggage, used furniture, or clothing. These tiny, reddish-brown insects hide in mattress seams, bed frames, and baseboards, making them difficult to detect until the infestation spreads. Common signs include small red bite marks on the skin, dark spots of excrement on bedding, and the presence of shed skins.
Unlike other pests, bed bugs don’t transmit disease, but their bites can cause itching, allergic reactions, and sleepless nights. Washing bedding on high heat, using mattress encasements, and reducing clutter can help limit their spread. Still, complete elimination usually requires professional bed bug control using heat treatments or targeted chemical applications. Acting quickly is key—delays allow bed bugs to multiply and spread to new areas of the home.
Wasps & Hornets
Wasps and hornets are more than just outdoor nuisances—they can become a serious hazard when they build nests close to homes in Scarborough. These stinging insects often nest under eaves, inside wall voids, or in the ground, and their aggressive behaviour makes removal risky. Signs of a problem include frequent wasp activity near your home, visible nests, or buzzing sounds coming from walls or attics.
Wasps are particularly dangerous for people with allergies, as even a single sting can trigger severe reactions. To prevent infestations, seal cracks in exterior walls, cover vents with mesh, and keep food and garbage containers tightly sealed outdoors. DIY nest removal can be extremely dangerous, especially with large or hidden colonies—professional wasp pest control is the safest option to eliminate nests and prevent reinfestation.
Fleas
Fleas and ticks are common pests in Scarborough households, especially those with pets that spend time outdoors. Fleas are tiny, jumping insects that bite animals and humans, causing itching and skin irritation. Ticks attach to the skin and can transmit dangerous diseases like Lyme disease. Signs of fleas include pets scratching excessively, flea dirt (small black specks) in fur or bedding, and small bites around ankles.
Ticks are often spotted on pets after outdoor activities or crawling on floors and furniture. To prevent infestations, treat pets regularly with veterinarian-approved flea and tick products, wash pet bedding in hot water, and vacuum carpets and upholstery often. A combined approach is needed for heavy infestations—treating pets and the home environment and, in some cases, professional flea pest control to ensure complete eradication.
When to Call a Professional
