What Affects the Cost?
Pest Type
Bed bugs and cockroaches require specialized treatments and multiple visits, costing 2–3x more than general pest control.
Infestation Severity
A minor ant problem is a quick fix. A severe rodent infestation requiring full exclusion and cleanup can run well past $1,000.
Property Size
Larger homes require more product and labour. Costs scale roughly with square footage for most treatments.
Treatment Method
Chemical sprays are cheapest. Heat treatment for bed bugs is more effective but costs $1,500–$4,000 for a full home.
Licensing in Ontario
Ontario pest control operators must be licensed by the Ministry of the Environment, Conservation and Parks (MECP). Technicians must hold valid pest control licences for the categories of pests they treat. Always verify licensing before hiring.
