Truly Nolen Pest and Termite Control was founded in Florida in 1938. They have since developed a service area spanning 18 states, and they maintain franchises in 30 other countries.
With over 80 years of experience, they’re equipped to handle just about any pest problem you may have. They treat challenging insects like termites and bed bugs, as well as more straightforward bugs, including ants, bees, wasps, beetles, crickets, earwigs, fleas, mosquitoes, roaches, and spiders.
In addition to their extensive insect treatments, they also remove rodents, birds, and other wildlife. They have less common services as well, including home sealing to prevent re-infestation, lawn packages that can improve grass and soil quality, and insulation installation to help regulate interior temperatures and deter pests simultaneously.
Truly Nolen doesn’t provide single treatments for pests and instead relies on contracts for service. They have specific agreements for bed bugs, termites, and certain wildlife, given the nature of the pests. Some rodents and the majority of other insects are covered in their 4 Seasons Pest Control Plan.
The 4 Seasons approach requires an annual contract and includes four scheduled visits each year. The treatments are effective against most common bugs, so it’s a relatively comprehensive protection plan. Truly Nolen offers a satisfaction guarantee on their agreements, and they include unlimited callbacks for additional inspections or treatments for as long as you’re their customer.
While the 4 Seasons plan applies only to residential properties, Truly Nolen does offer a variety of services to commercial customers as well. They have plans designed for non-food and food-based establishments, each of which includes different pests treated monthly. For more specific pest management, they offer several dedicated treatments, such as commercial bee service, bird control, or rodent control.
Both their single and ongoing services are expensive when compared to larger national companies like Terminix. As such, you may end up paying more for pest management with Truly Nolen.
While they may be more expensive, their exterminators are well-trained and typically provide adequate service that will solve your pest problem. They’re professional and knowledgeable about the pests they handle, and the company as a whole invests a lot of time and money into teaching its employees the current best practices.
The efficacy of their work is reflected in their generally positive reviews, and most customers are pleased with the results of their treatment. Some have complained about a lack of responsiveness, but the opinion about the actual service is overwhelmingly positive.
They offer free estimates on their website for some customers in their service area, but you may need to contact the individual franchise depending on where you live and the pests you’re experiencing. For new customers, they regularly take $50 off of service agreements for general pest control and $100 off of their termite plans. They have a referral program that can earn you $25 when you refer their service to a friend or family member.
They use an integrated pest management plan that can be pet-safe, and they advertise that they use eco-friendly pesticides and rodenticides whenever possible.
Truly Nolen has a long-standing history of successful pest management, and they provide services for a wide range of insects and rodents. They’re typically more expensive than other national pest control companies, but they provide effective service and guarantee your satisfaction with their results. They offer eco-friendly and pet-friendly treatments, and they have comprehensive, annual agreements for residential and commercial customers.

FAQs for Pest Control in Ontario, CA

What are the most common pest problems in Ontario?

Termites are a serious threat to homes and businesses in the US. This wood-destroying pest causes billions of dollars worth of damage each year. Getting rid of them is usually a condition for selling a home.

Bed bugs are parasitic insects that need human or animal blood to live. They make their nests in the cracks and crevices of furniture and bedding. And they are hard to get rid of without the help of a professional exterminator.

Mosquitoes. There are more than 50 species of mosquitoes in California.  They can be found in the desert as well as wetland areas. And they breed quickly, so it’s best to eliminate stagnant water traps around a home or business.

Bees and other stinging pests are a nuisance mainly because of the public’s fear of them. However, they can be beneficial to the local ecosystem. That’s why it’s essential to seek advice from a professional before relocating them.

Spiders rarely bite people. But on occasion, it can happen. However, for the California tarantula, that’s not the case. Although it contains venom, human encounters don’t happen very often. 

What is the average cost of pest control in Ontario?

The average cost for a one-year pest control contract in Ontario is between $300 and $550. That comes out to about $40 to $70 per month.

The exact price depends on the type of pest and the level of infestation. For example, a bee removal job may cost $500 to $1,000. But a large termite infestation may be between $2,000 and $8,000.

Bed bugs are also a tricky pest to eradicate. Plan on prices ranging from $500 up to $1500 or more.

How to choose a pest exterminator in Ontario?

  2. Check online review sites to get a feel for how you may be treated as a customer.
  3. Ask about treatment methods used by the exterminator before agreeing to the service.
  4. Seek the advice of family and friends. Also, ask the neighbors who they use for their pest control provider.
