Top Pest Control Brands in Ontario

When ranking these pest control providers, we considered several factors such as coverage, industry experience, types of pest control treatments offered, customer service, and more.

Here’s how Ontario’s top companies ranked:

Terminix

Terminix has several hundred branches in over 22 countries and has been in the pest control industry for almost 100 years. With this experience, you can see why Terminix is one of the top companies in the country.

Terminix provides both one-off extermination services and routine pest control. Additionally, every contract comes with a 30-day guarantee. Their service also comes with follow-up visits and annual inspections to help keep your home pest-free.

Orkin

If you need immediate pest control service in Ontario, Orkin could be the company for you. Since 1901, Orkin has become one of the largest pest control companies in the country. Because of its large network, Orkin can offer same-day or next-day service.

Orkin’s most common pest control plan is its annual pest control contract. After the first visit, your pest control specialist will follow up regularly to make sure that the pests have stayed away for good. If they have, your local technicians can help

Rentokil

Rentokil has been helping homeowners and business owners rid themselves of common pests for over 90 years. In North America, Rentokil is the parent company of quite a few local pest control companies like J.C. Ehrlich, Western Exterminator, and Presto-X.

Rentokil deals with the common pests in Ontario, including ants, moths, wasps, flies, bees, cockroaches, bed bugs, spiders, mosquitoes, and crickets. After the initial inspection and treatment of your property, a technician will treat your property as often as your contract states.

How To Choose a Pest Control Company

Not all pest control providers are the same in credibility, qualifications, and proficiency. Evaluating services helps you identify the right choice for your pest problem. Focus on these key factors when choosing a pest control provider:

Services Offered

It's recommended to look for a pest control company that primarily handles the pest you have, like termites, bed bugs, roaches, or rodents. The company should describe how they go about treating your type of pest.

Expertise

When selecting a pest control provider, look for technicians that have the proper state licensing and are certified in pest control methods by industry associations such as the National Pest Management Association (NPMA). Possessing these credentials shows that a technician has adequate training. Question the company about the training hours required for its technicians as well as its policies for continuing education.

Experience and Reputation

We highly recommend checking out customer reviews prior to scheduling a pest control appointment. Google, Yelp, and other review sites can tell you whether a company consistently provides quality service and has happy customers. Also check for any Better Business Bureau complaints that have been filed. Ask about the kind of continuing education technicians receive to stay current on best pest control practices. When you select a company from our list of Ontario's best pest control, you can feel confident knowing that you're hiring an expert that meets our quality and review standards.

Green Pest Control

If you prefer more natural, eco-friendly pest control solutions, look for providers that have "green" accreditations. If you’re dealing with larger pests, such as mice or raccoons nesting in trees, you can also ask about humane catch and release. Bear in mind that natural pest control options may be less effective; consider the traditional route if dealing with a serious infestation. Regardless of what methods you choose, any pesticides that are classified as greater than minimal risk must be registered with the EPA.

Reservice Guarantee

Reliable pest control providers typically offer service guarantees for recurring plans. These guarantees mean the provider will make another visit and re-treat your home for free if there are still pests after the first treatment. One-time services may not include reservice guarantees.

Questions To Ask Pest Control Companies

Once you have found your top pest control providers, contact each one with these questions:

  • What results should I realistically anticipate after the initial and follow-up visits? The company should establish clear expectations about pest eradication timelines and benchmarks.
  • Can you provide your full price breakdown and service plan in writing upfront? This allows you to get an idea of pest control costs and avoid companies with vague conditions or surprise fees.
  • When can you start treating my home? It's important to start promptly before the problem spreads.
  • What pest control procedures and approaches do you use? Ensure that the methods match your preferences for more standard treatment plans versus eco-friendly options. Ask the company for details about what pesticides or chemicals it plans to apply.
  • How many times throughout the year will you need to treat my property once the initial visit is complete? Most companies offer regular, semi-regular, or annual service plans to check for reinfestations.

Take the time to thoroughly review pest control providers using these questions. This will help you choose the best provider to safely and successfully get rid of your pest problem at a fair price.

Frequently Asked Questions About Pest Control in Ontario, CA

Our top picks for pest control companies are Orkin and Terminix. They're well-respected in the industry and cover all common pests.

Hiring a pest control company and getting a professional to spray your property regularly is the best way to prevent future pest infestations. This deters insects and other wildlife from coming inside your home.

There are some pests you can get rid of yourself. For example, if you see some ants or a rogue wasp, chances are you can take care of it on your own. But some cases warrant bringing in the professionals. If you have a big infestation, you aren’t sure what the pest is, or would like preventative pest control, you should hire a pest control company.

A pest control company exterminates unwanted insects or animals that have infested your property. Pest control also includes preventative measures taken to stop those pests from coming back, which can happen at any point in a warm place like Ontario.

In a city like Ontario, where the cost of living is noticeably high compared to other cities, the cost of pest control is most likely a concern. The cost of pest control varies based on several factors, such as what kind of pests you have an issue with and how bad the infestation is. A single visit can cost between $300 and $500, but a quarterly treatment plan is usually cheaper — around $100 to $300 a visit.

Spring is the best time for proactive pest control. The reason is nests and colony numbers will get much higher when it's hotter, so spraying in the spring can help prevent you from getting too many pests later.
