ANTS
Ants are a common household pest in Ontario, often seen trailing in search of food or nesting indoors. While most are nuisance pests, some species can damage property or contaminate surfaces. Professional treatment helps eliminate colonies and prevent repeat infestations.
COCKROACHES
Cockroaches are resilient pests commonly found in kitchens, bathrooms, and other moist areas. They can spread bacteria, trigger allergies, and multiply quickly if not treated promptly. Professional extermination is often necessary to ensure full elimination and prevention.
BED BUGS
Bed bugs are small, blood-feeding pests that hide in beds, furniture, and cracks in walls. They bite at night and can cause itching, allergic reactions, and stress. Infestations can spread quickly and require professional heat or chemical treatments to fully eliminate.
SPIDERS
Spiders are common in Ontario homes, especially in basements, garages, and corners. While most are harmless and help control other pests, some species can become a nuisance. Regular cleaning and sealing entry points can reduce indoor spider activity.
WASPS & HORNETS
Wasps and hornets are aggressive stinging insects that often build nests around homes, roofs, and trees. Their presence can be dangerous, especially for people with allergies. Safe, professional nest removal is the best way to prevent stings and reinfestation.
FLIES
Flies are fast-breeding pests commonly found around food, garbage, and drains. They can spread bacteria and disease, especially in kitchens and commercial settings. Identifying the source and maintaining sanitation is key to effective fly control.
OCCASIONAL INVADERS
These pests—like silverfish, earwigs, centipedes, and stink bugs—enter homes seasonally or after weather changes. Though not always harmful, they can become unsettling and multiply quickly if left unchecked. Exclusion and moisture control are key to prevention.
RODENTS
Mice and rats are serious indoor pests that can chew through wires, contaminate food, and spread disease. They often enter homes through small gaps and can reproduce quickly. Effective rodent control combines exclusion, trapping, and sanitation.
STORED PRODUCT PESTS
These pests infest dry food products like grains, flour, cereals, and pet food. Common species include moths, weevils, and beetles. Infestations often begin unnoticed and can spread quickly. Discarding contaminated items and professional treatment are key to control.
MOSQUITOES
Mosquitoes are blood-feeding pests that breed in standing water and thrive during warmer months. Their bites can cause itching, allergic reactions, and transmit diseases. Regular yard treatment and water source reduction help keep mosquito populations under control.
BIRD / PIGEON CONTROL
Pigeons and other nuisance birds can cause property damage, slip hazards, and health risks from droppings. Effective control includes netting, spikes, and cleanup solutions to prevent nesting and keep your property clean and safe.
BUGS & OTHER INSECTS
This group includes beetles, stink bugs, ladybugs, and other occasional home invaders. These pests often gather near lights, windows, or warm areas and may appear in large numbers. Sealing cracks and regular inspections help reduce infestations.
