Safe, Effective Pest Control Tailored for Ontario Living
At Crest Pest Control, we specialize in providing pest control solutions tailored for Ontario residents—from homes near Ontario Mills and the bustling downtown area to those in the peaceful neighborhoods. Our mission is to deliver reliable, long-lasting protection that keeps your family safe while caring for the unique environment of our Inland Empire community.
Smarter Pest Solutions
We understand the unique pest challenges that come with living in Ontario. Every service begins with a thorough inspection to identify the source of your pest problems. From there, we create a customized plan that addresses your current issues and helps prevent future infestations.
Using Integrated Pest Management (IPM) strategies, we apply targeted, low-impact treatments that reduce chemical use while delivering effective results.
Ant Control in Ontario
Ants can quickly become a major nuisance, invading kitchens, pantries, and even walls. We identify the ant species causing the problem and locate their nests to treat at the source. Using proven, low-impact methods, we eliminate the colony and help seal entry points to keep ants from coming back.
Flea & Tick Control in Ontario
With many families and pets enjoying outdoor activities, fleas and ticks pose serious health risks. Our flea and tick control treatments focus on breaking their lifecycle by targeting adult pests and their eggs. We treat yards, shaded areas, and pet bedding zones to provide a safer environment for your family and furry friends.
Mosquito Control in Ontario
Mosquitoes don’t just cause itchy bites—they can also carry dangerous diseases. Ontario’s warm climate and green spaces offer perfect breeding grounds for these pests. We target standing water, dense vegetation, and other key habitats to drastically reduce mosquito populations, making your yard safer and more enjoyable.
Rodent Control in Ontario
Rodents like rats and mice aren’t just a nuisance—they can damage property and spread harmful germs. Whether you hear noises in your attic or notice droppings in the garage, we respond quickly with sealing techniques, traps, and ongoing monitoring to keep rodents out for good.

Frequently Asked Questions
How much does your service cost?
Our pricing depends on the size of your home, the pests we’re treating, and the frequency of service needed. In Ontario, we offer general pest control plans starting as low as $45 per month, and every service begins with a free inspection. We’ll provide a personalized, no-pressure quote so you know exactly what to expect—no surprises.
How often should I have my home treated for pests?
For homes in Ontario, we typically recommend bi-monthly service to provide consistent protection against local pests. However, properties with higher pest activity, coastal landscaping, or previous infestations may benefit from monthly treatments. We’ll assess your situation and tailor a treatment schedule that works for your lifestyle and keeps your home pest-free year-round.
Do you provide exclusion services for rodent control?
Yes—we offer light rodent exclusion services. That means we’ll identify key entry points and provide basic sealing where necessary, along with setting traps and applying proven rodent control methods. While we don’t offer full structural repairs, we’ll help minimize entry and give you clear guidance on preventing future activity.
Are your treatments safe for my family?
Absolutely. The products we use are EPA-approved and professionally applied, meaning they’re safe for children and pets when used as directed. We always take extra care during treatments and are happy to explain exactly what we’re using and why. Your safety and peace of mind are always our top priorities. We also have eco-friendly solutions available.
Do you offer a satisfaction guarantee?
Yes. We guarantee a 5-star service on your initial visit or your money back. For our maintenance plans, if pests return between scheduled visits, just give us a call—we’ll come back and re-treat at no additional cost. We’re not happy unless you’re pest-free and completely satisfied with our service.
Is there a contract I have to sign?
No long-term contracts required. We offer flexible service plans—including one-time, seasonal, and recurring treatments—so you can choose what works best for you. You’re never locked in, and you can pause or cancel your plan at any time.
