How To Choose a Pest Control Company

The most important step in the pest control process is hiring the right company for you. Along with a company's qualifications and pest extermination methods, you may also look into how long it has been in business and what the reviews look like. Finally, you'll likely want to consider the cost of services.

Below, we explore the details of each of these factors.

Does the company have a valid license and permits to perform pest control?

According to the United States Environmental Protection Agency (EPA), all pesticide applicators and their supervisors need to be licensed at the state level. The EPA sets minimum competency standards, and the Missouri regulatory agencies handle the issuing, maintaining, and revoking of licenses.

Is the company a member of any professional organizations?

Pest control companies can optionally obtain certifications from QualityPro or similar trade organizations. These certifications can help you assess the quality of a company's products. For example, the GreenPro Service Certification indicates comprehensive and effective pest control methods that are safer for people and the environment.

Pest control companies can also belong to certain professional organizations. Joining an organization such as the National Pest Management Association (NPMA) or a state-level organization grants a pest control company access to resources and education, as well as a professional network to compare best practices with. Belonging to organizations like these is not required, but it can help show that a company follows industry best practices.

Professional Experience and Specialties

In general, a company will list information like its years of experience and specialities on its website. Local reviews can also tell you whether a company has experience dealing with a particular pest in your area. If you can't get the information you need online, you can speak with a company representative directly to get the answers to your questions.

Reviews and Recommendations

You can verify a company's legitimacy using social media or local review sites as well as the Better Business Bureau (BBB). You can also check with Missouri's licensing board to verify the status of a company's license.

Cost of Services and Guarantees

Cost is important when picking a pest control company. Cost may be determined by the type of pest being treated, your location, the size of your house, and other factors.

Certain pest control companies offer a free on-site estimate to help you match services to your budget. You can also see if it offers a guarantee of satisfaction.

Safety and Treatment Methods

When it comes to picking a pest control provider, you want to choose a company that will help keep you, your family, and your pets safe. You'll likely also prefer an eco-friendly provider.

Safety

You want to ensure that you understand the precautions around pesticides being used in your home, for the sake of your family, your pets, and yourself. Your pest control provider should be able to supply information about all pesticides they plan to use, whether they are low toxicity or non-toxic, and (if not) what safety measures will be in place. All pesticides (except minimum-risk ones) should be registered with the EPA.

Treatment Methods

Many companies have started offering options for more eco-friendly methods of pest control before relying on harsh pesticides.

One popular way of making pest control safer and more eco-friendly is Integrated Pest Management (IPM). The steps of IPM are as follows:

  1. Identify problem pests and assess whether immediate action is required.
  2. Decide on the safest course of action.
  3. Use a combination of biological, cultural, mechanical, and physical controls to manage the pest problem.
  4. Employ chemical controls only when absolutely necessary, and always along with other techniques for effective long-term pest management.
  5. Evaluate outcomes and continue with additional pest control as needed.

Common Household Pests in St. Charles

Not all pests are equally common in St. Charles. Some species that you should be on the lookout for include the following:

  • Snakes: Snakes prefer dark, damp, and cool places like basements and often come into a home looking for food. Most species of snakes are harmless, but this is not a risk that you and your family want to take.
  • Moths: If you are noticing holes in your clothing or linens, you might have moths in your house. Moths prefer dark places like closets, and they're more common in warmer places.
  • Wasps: In many cases, wasps are difficult to get rid of, especially if you're trying to avoid being stung. They are commonly found in spots like garages, attics, sheds, and roof overhangs.
  • Mice: Some common signs of mice include chewed wires and droppings around your house. Mice are commonly found in attics or in areas where food is stored.
  • Spiders: These pests prefer dark and damp places and are commonly found in basements or attics.
