Why Every New Home Buyer Should Book a Pest Inspection
A home inspection is not a pest inspection. Here is what a general pest inspection covers, why it matters before closing, and when GTA buyers should book one.
By Deev Patel
Buying a home is one of the most exciting — and expensive — milestones in life. Whether it's your first house or your fifth, there's a lot to check off the list: financing, closing, renovations, inspections. One step that gets skipped more often than it should is a general pest control inspection before or shortly after you take possession.
Why a pest inspection matters before you buy
When you walk through a potential new home, you're looking at finishes, room sizes, and maybe renovation plans. What you can't see without a trained eye are the pests that may already be in the walls, attic, basement, or foundation. Termites, carpenter ants, rodents, cockroaches, and bed bugs can all be present in a house that shows well.
A standard home inspection is not a pest inspection. Home inspectors look at structure, roofing, electrical, and plumbing. They are not required to identify frass, harbourage, droppings, or the entry points that let wildlife into a roofline.
Protect the investment
A home is likely the biggest purchase you'll ever make. Carpenter ants excavate wood to nest rather than eating it, and Health Canada notes they are well known for damaging wooden structures. The damage accumulates quietly, often for years, before anything is visible from the living side of a wall.
Catch problems while they are still small
Early signs of infestation are easy to miss. A licensed technician knows what to look for — entry points, droppings, damage patterns, and moisture hotspots that attract wood-nesting insects. Catching an issue at that stage is usually faster and cheaper to resolve than treating an established colony. The Sterex pest library covers the signs for each pest we treat in the GTA.
Health considerations
Pests don't just cause damage. Health Canada's guidance on cockroaches notes that people with asthma may react to cockroach droppings and body parts, and that cockroaches can contaminate food and food preparation surfaces after travelling through garbage or sewers. Rodents contaminate food and surfaces in the same way. Starting in a home with no active activity removes that variable.
Reduce the chance of a new infestation
Even if a home is currently clear, a preventive exterior treatment and a check of entry points make it harder for pests to establish. Health Canada's position on cockroaches is a good general rule: cleaning and pesticides work together, and pesticides alone will not do it. Sealing gaps and fixing moisture matters as much as any product.
Leverage before closing
A professional pest inspection either gives you peace of mind or gives you something concrete to raise before closing. Finding an active carpenter ant colony during the conditional period is a very different conversation from finding it in year two.
What a general pest inspection includes
At Sterex Pest Control, our general pest inspection covers:
- Full exterior and interior inspection
- Identification of current and potential pest issues
- Recommendations for treatment and prevention
- An optional preventive treatment, applied according to the product label
Any product we apply is registered with Health Canada and carries a PCP number on the label. Re-entry and ventilation instructions come from that label, and the technician goes through them with you before leaving. You can read how Health Canada registers pest control products if you want the background.
When to book it
Whether you just closed or you're still in the offer stage, it's rarely too early. Sterex offers general pest control for new home buyers across the GTA, including Toronto, Brampton, and Mississauga. The Ontario pest control pricing guide sets out what a general treatment costs, residential pest control explains the ongoing options, and the prep checklists cover what to do before a visit.
