We've narrowed down the best pest control experts so you can find the best provider for you. We analyzed state availability, customer reviews, pest control treatments offered, costs, contracts, and more.

Here’s how we ranked them:

Terminix’s headquarters are in Memphis, Tennessee, but it has branches in 45 states and several countries globally. It has also been in the industry for almost 100 years. With the amount of experience the company has, it’s easy to see why Terminix is one of the top companies in the country.

Terminix treats all kinds of pests in Ontario, and it guarantees that your pest problems will be solved. Terminix’s general pest regimen consists of a home inspection and preliminary treatment, with three seasonal treatments during the year.

Orkin

Founded in 1901 by a rat poison salesman named Otto, the Orkin brand has grown to be one of the most trustworthy in the pest control industry. Due to its vast network, Orkin can offer same-day or next-day service.

Pests Orkin helps with are cockroaches, crickets, bees, moths, scorpions, flies, fleas, carpenter ants, ticks, termites, and more. Each contract with Orkin comes with a 30-day satisfaction guarantee. If your pest problem isn't handled, your technician will return for another visit.

How To Choose a Pest Control Company

Pest control providers vary in reputation, understanding, and capability. It's important to research companies to find the right fit for your pest problem. Here are the key factors to consider when choosing a pest control company:

Services Offered

Look for a pest control company that has extensive experience treating the type of pest you're dealing with, whether it's termites, bed bugs, roaches, rodents, or something else. The company should provide detailed explanations of its area of expertise.

Expertise

Look for pest control companies that employ technicians with certifications in pest control methods from qualified industry groups, such as the National Pest Management Association (NPMA), in addition to state licensing. Possessing the proper credentials indicates that the technicians have received adequate training. Also ask about ongoing educational requirements.

Experience and Reputation

Read through reviews on Google, Yelp, and similar sites before booking a pest control appointment. Confirm through customer feedback that the company reliably provides effective service and receives positive customer feedback. Also check for any Better Business Bureau complaints that have been filed. Ask whether technicians receive ongoing education on the most cutting-edge pest control treatments. When you choose a professional from our list of the top pest control in Ontario, you can rest easy knowing you're hiring an expert that meets our quality and review standards.

Green Pest Control

Search for providers that have “green” certifications if you want more natural, eco-friendly pest control. You can also ask about gentle catch and release methods for larger animals like mice or snakes. Keep in mind that stronger solutions might be a better option for major infestations. No matter your approach to pest control, all pesticides (besides those classified as minimal risk) are required to be registered with the EPA.

Reservice Guarantee

Leading pest control companies typically offer service guarantees for ongoing plans. This means that if pests remain after the initial treatment, the company will make another visit and re-treat your home at no cost until the infestation is handled. One-time treatments may not come with reservice guarantees.

Questions To Ask Pest Control Companies

After picking your top exterminators, reach out to each one with questions such as these:

  • What results can I typically expect after the initial and follow-up treatments? The company should provide a clear timeline for when pests will be eradicated.
  • Can you give me detailed pricing information and service plan details in writing? This lets you get an idea of the price of pest control and avoid companies with vague conditions or hidden fees.
  • When can you start inspecting or servicing my home? It's important to begin treatment ASAP before the infestation worsens.
  • What pest control plans and procedures does your company use? Make sure the techniques align with your goals for traditional options versus natural options. Get details about the active ingredients and compounds that the company will use.
  • How often will you provide ongoing care after the first treatment? Most companies offer regular, semi-regular, or annual service plans to look for signs of reinfestations.

Carefully review potential pest control companies using these questions. This will help you choose the right provider to safely and effectively get rid of your pest problem at a reasonable price.

Frequently Asked Questions About Pest Control in Ontario, CA

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

Hiring a pest control company and getting a professional to spray your property routinely is the best way to prevent future pest infestations. This deters insects and animals from coming inside your house.

Pest control involves exterminating unwanted bugs like termites, rodents, and other unwanted bugs or wildlife from your home. When you hire a pest control company, a professional exterminator will come and inspect your property. Then they will use various methods to remove the pests and prevent them from coming back, such as chemical or natural sprays, bait, and traps.

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

If you already have a serious infestation, you should seek pest control as soon as possible. However, if you’d just like preventative pest control, the best time of year to have a professional come spray your home is in the spring before nest and colony numbers get too high in the hotter part of the year. But it’s never too late for pest control. You can still spray in the summer or any other season and see effective results.
