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 San Marcos, CA

What are the most common pest problems in San Marcos?

Termites. The drywood termite lives above ground and doesn’t need constant contact with the soil like other termites. For that reason, they can be hard to identify and treat.

Fumigation methods are sometimes the only solution to these wood-destroying pests.

Bed bugs are tiny, lintel-colored insects that rely on human and animal blood for survival. They hide in mattress seams and other concealed locations. The best way to eliminate bed bugs is by using several methods at the same time. 

Mosquitoes breed rapidly when standing water sources are available in abundance. That’s why it’s vital to remove debris that can catch rainwater. Exterminators have many tools at their disposal to get rid of this biting menace.

Bees are beneficial for the environment since they provide food for birds and animals. But they become pests when they make large hives or swarm around trees in residential areas. The best way to remove them is by enlisting the help of a professional beekeeper.

Spiders. The California tarantula is the scariest-looking spider in the area. But you have to be more careful of the black widow. It contains a potent venom that can send most people to the emergency room.

What is the average cost of pest control in San Marcos?

The median price for pest control in San Marcos is $179, with an average range between $113 and $268. However, the exact cost depends on these factors:

  • Pest type
  • Infestation level
  • Methods used by the exterminator
  • Square footage

For example, a one-year agreement will typically run between $40 and $70 per month. And the pests included are:

  • Roaches
  • Spiders
  • Ants
  • Mice

However, bee removal is normally extra and is usually priced from $100 to $1,000. Bed bugs are typically $500 to $1500, while termite treatments can run between $2,000 and $8,000 or more.

How to choose a pest exterminator in San Marcos?

  1. Start with review sites to get an idea of what’s available in San Marcos.
  2. Check with the Better Business Bureau to determine which pest control companies are the most reputable.
  3. Ask about the service methods used, including the types of pesticides and their overall safety.
  4. Be sure only to consider those exterminators that are licensed, bonded, and insured in California.
  5. Ask about the company’s service warranty or guarantee.

Which companies in San Marcos have eco-friendly solutions?

Terminix cuts down on the use of pesticides by utilizing long-term insect growth regulation technology.

Carmel Valley Pest Control preserves the local environment by sourcing only the best, EPA-approved, organic sprays for its perimeter barriers.

Orkin technicians employ bait gels and granules instead of relying on harmful chemicals for treating ants and roaches. 

Green Flash Pest Control is a locally owned and operated business that protects children and pets by utilizing targeted methods such as crack and crevice applications.
