Those few ants on the windowsill are scouts for a much larger group. Our treatment reaches the nest behind the wall or under the slab where they actually live.
Ant control servicesOntario homes can be hit by drywood termites. By the time the damage shows, the colony has usually been working for months, so prompt professional treatment is essential.
Termite control servicesOne mouse becomes a dozen in weeks, gnawing wires and contaminating food long before you spot the first one. Ontario Pest Control provides complete rodent control with exclusion and treats the root cause.
Rodent control servicesItchy bites and tiny blood spots on your sheets are early signs of bed bugs. Don't try store-bought sprays. Our heat treatment eliminates them at every life stage.

Pest control in Ontario isn't a side market for us, it's all we do here. Ontario Pest Control has built its reputation one Ontario home at a time, learning which pests show up where and when, so the treatment you get is tuned to this area rather than copied from a national playbook.
Anyone can spray a baseboard. Lasting results come from understanding the property and the pest together, and that's where our years working in Ontario pay off, fewer callbacks, faster resolutions, and protection that actually holds.
One call connects you with a Ontario technician who can size up the problem and book your free inspection.
From the first call to ongoing protection, our method is built to solve the problem completely the first time.
Call (909) 273-6048 and we'll schedule a free inspection, often the same day. We'll ask a few quick questions and book a time that works for you.
We don't guess. The inspection covers the whole home, identifies the pest and its source, and turns into a straightforward treatment plan with the cost spelled out up front.
Using family- and pet-safe products, we treat the infestation directly and address the conditions that attracted pests in the first place.
We check that the treatment held, then offer recurring plans that stay ahead of pests all year by addressing the source instead of the surface.
Free inspections · Same-day service available
There's no mystery to how we handle an urgent infestation. Here's the step-by-step of what Ontario Pest Control does after a Ontario homeowner calls for same-day help.
You call (909) 273-6048. A real person picks up, assesses your situation, and sets up same-day or next-day service for your Ontario home.
Often within hours, our fully equipped technician is on-site with all the products required to inspect and begin treatment in your Ontario home or business.
The technician confirms exactly what's infesting the home and where it's coming from, then treats it on the spot, hitting the active pests and sealing or addressing the spots that let them in.
We don't disappear once the visit is done. We follow up to confirm the pests are gone and, for problems that tend to return, set you up on a recurring plan with monitoring between visits so the issue stays solved.
"We had ants pouring into the kitchen every single morning and nothing from the store worked. Ontario Pest Control tracked down the trails, treated the nest at the source, and they were gone within days. Months later and we still have not seen a single ant come back."
"Spiders had taken over our garage and porch. The tech treated every corner and explained how to keep them out. Friendly, efficient, and very knowledgeable. Highly recommend these folks."
"Bed bugs were a nightmare and we were embarrassed to even call. The team was reassuring and discreet. Their heat treatment knocked them out in one visit and the follow-up confirmed we were clear. Cannot recommend them enough."
Choosing a pest control company is a big decision. Here's what sets Ontario Pest Control apart from other Ontario pest control companies.
The difference shows up in the results. Our technicians have logged real years in the field, so they read the situation correctly the first time and apply the right treatment instead of working through trial and error on your home.
