    How To Choose a Pest Control Company

    When choosing a pest control company, there are a number of things that you can consider to be sure you choose the best one for you. The qualifications of and treatment methods used by a company are important to consider, as well as its years of experience and what other customers have said. Of course, you also want to consider cost.

    Below, we dive into detail on each of these factors.

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

      Per the United States Environmental Protection Agency (EPA), all pesticide applicators and their supervisors are required to be certified at the state level. The EPA does set minimum standards of competency, but all pesticide applicators in Colorado must be licensed through the proper state regulatory agencies.

    • Is the company a member of any professional organizations?

      A pest control company can obtain optional certifications from QualityPro or similar trade organizations in order to support its standards and methods. One particular certification is the GreenPro Service Certification, which is awarded when a company can demonstrate that its methods are more environmentally friendly. A company that receives this certification also needs to maintain certain employee training standards.

      A pest control company can also belong to professional organizations. Membership in an organization like the National Pest Management Association (NPMA) or a state-level organization gives companies access to education and resources, as well as a professional network to compare best practices with. Joining one of these organizations is not mandatory, but it can help indicate that a company follows industry best practices.

    Professional Experience and Specialties

    You can look at a company's years in business to help determine how much experience it has handling pests in your area. You can also explore its website or peruse customer reviews to determine whether it has adequate experience with the type of pests you are looking to get rid of. If you cannot find this information online, calling the company directly is a great way to learn more.

    • Reviews and Recommendations

      Resources that can help you verify a company's reputation include social media, local review sites, and the Better Business Bureau (BBB). You can also check the status of a company's license through the Colorado licensing board.

    • Cost of Services and Guarantees

      Cost is an important consideration when choosing 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.

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

    Safety and Treatment Methods

    When it comes to choosing a pest control provider, you want to choose one that will help keep you, your family, and your pets safe. You'll likely also prefer a provider that is environmentally-conscious.

    • Safety

      All pesticides (except those that are determined to be of minimal risk) are required to be registered with the EPA. Your pest control technician should provide you with information on each pesticide they will be using. They should be able to tell you whether the pesticides are low toxicity or non-toxic, and if not, what safety precautions they plan to take.

    • Treatment Methods

      Many companies are now exploring greener and cleaner pest solutions that can be used before (or in place of) chemical pesticides. Many are following the practice of Integrated Pest Management (IPM), which goes as follows:

      1. Figure out what pests are causing the problem and determine if immediate action is needed.
      2. Decide on the safest course of action.
      3. Use a combination of physical, biological, mechanical, and cultural controls to manage the pest problem.
      4. Employ chemical controls only when required, and always with other controls for effective long-term pest management.
      5. Evaluate outcomes and continue with additional pest control as needed.

    Common Household Pests in Thornton

    Certain pests are more common than others. In Thornton, common pests to be watchful for include the following:

    • Beetles: In Thornton and across the country, there are a diverse array of beetles that could create problems. While many beetles are harmless, others can do damage by eating carpeting, wood, and more.
    • Mice: Some common signs of mice include chewed wires and droppings around your house. Mice are commonly found in attics or in places where food is kept.
    • Bed bugs: Bed bugs may be found throughout Colorado and can lead to major problems if left untreated. Because infestations of bed bugs are tricky to get rid of, we recommend having professional extermination as soon as you discover the problem. Bed bugs can infest wallpaper, furniture, bedsheets, and more.
    • Spiders: These pests prefer moist, dark places and are often found in basements or attics.

    Frequently Asked Questions About Pest Control in Thornton

    What causes pest infestations?

    Pests come into your home looking for one of three things: food, water, or shelter. Some pests will opportunistically enter your home through a broken screen or foundation crack. Some are drawn by food, either actual food left out or trash sitting out in the open. Others look for water, whether it be standing water on your property or puddles inside from things like leaky pipes.

    How can I prevent pest infestations?

    One way to prevent pest infestations is seal off possible entrances into your home. These include things like cracks in your foundation or siding. Also try to avoid leaving out food for pests. This includes keeping food in sealed containers as well as not leaving trash out. Finally, eliminate standing water in and around your home. Work to reduce places where water collects outside, and repair leaks inside.

    How frequently should I hire a pest control professional?

    Typically, it's recommended that you have your house treated for pests approximately once a year, more often if you have an active infestation. Your pest control professional will ultimately be the best person to recommend a treatment schedule for you.

    Should I clean after pest control services?

    Whether you need to clean your home following pest control services will vary depending on what treatments are used. Be sure to ask your pest control technician before they leave. In many cases, you will be able to dust, vacuum, and wipe down certain surfaces, although you should be careful not to wipe away chemical barriers or touch any traps unless you have been explicitly told to do so. You might notice a lingering smell following the application of some pesticides.

    Following pest control, it is important to maintain a clean home to discourage pests from returning.
