    How To Choose a Pest Control Company

    Choosing the best pest control company for you is key. The qualifications of and treatment methods used by a company are important to consider, as are its years of experience and customer reviews. Of course, you will also want to think about cost.

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

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

      All pesticide applicators (and those that supervise them) are required to be certified at the state level. The United States Environmental Protection Agency (EPA) has established minimum standards of competency, but all pesticide applicators working in Colorado must be licensed via the necessary state regulatory agencies.

    • Is the company a member of any professional organizations?

      Obtaining additional optional certifications can help show that a pest control company is reputable. One of these is the GreenPro Service Certification. For this certification, a company must prove that its methods are more environmentally friendly and that its employees receive up-to-date training. Other various certifications can be earned through QualityPro and similar trade organizations.

      Pest control companies can also obtain membership in professional organizations. While not mandatory, membership in organizations such as the National Pest Management Association (NPMA) or state-level organizations help verify a company's reputability. In the NPMA and other organizations, pest control companies have access to education, resources, and a network of other professionals with whom to share best practices.

    Professional Experience and Specialties

    How long a company has been in business can shed some light on its experience dealing with pests in your area. Customer reviews or the company's website itself can also help you figure out whether it has the skills and experience needed to eliminate the particular pests that are plaguing you. If you can't find the information you need online, contacting the company directly is an excellent way to learn about its areas of expertise.

    • Reviews and Recommendations

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

    • Cost of Services and Guarantees

      Things like the type of pest being treated, the size of your house, your location, and other factors can all affect the price of pest control.

      You can look into whether a company provides free on-site estimates (to determine if it fits in your budget) and what sort of guarantees it provides. Often, a company will guarantee that if it does not solve your pest problem, it will keep coming back until it does.

    Safety and Treatment Methods

    Your preferences regarding safety for yourself, any children or pets, and the environment might influence which provider and treatment methods you choose.

    • Safety

      Your pest control provider should use low toxicity or non-toxic pesticides whenever possible. If they plan to use pesticides that don't fit into one of these categories, your technician should explain what safety precautions will be used to protect you, your family, and your pets. Any pesticides that pose more than a minimum risk must be registered with the EPA.

    • Treatment Methods

      Many companies will start with more environmentally friendly options before employing pesticides, using a framework called Integrated Pest Management (IPM). When using IPM, the following steps are taken:

      1. Identify the source of the pest problem and determine whether immediate action is needed.
      2. Decide on the safest course of action.
      3. Use a combination of mechanical, cultural, biological, and physical controls to manage the pest problem.
      4. Use chemical controls only when required, and always along with other solutions for effective long-term pest management.
      5. Observe the results and provide additional pest control as needed.

    Common Household Pests in Windsor

    You might encounter some pests more frequently in Windsor. Some to keep an eye out for include these:

    • Snakes: Snakes often enter houses in search of food, and once inside they tend to prefer dark, damp, and cool places like basements. While the majority of snakes are harmless, most people don't want their family, their pets, or themselves to take that risk.
    • Moths: If you've been finding holes in your clothing or linens, there's a chance that you have moths in your home. Moths like dark places like closets, and they're more common in warmer places.
    • Ants: Ants can be found in just about every part of Colorado. Large carpenter ants can be an even bigger problem than regular soil ants, because they can cause structural damage to your home.
    • Bed bugs: Infestations of bed bugs can be very difficult to get rid of, so we recommend calling a professional as soon as possible. Bed bugs are found throughout Colorado, and can infest not only your bedsheets, but also other furniture and even wallpaper.
    • Mice: If you have a mouse infestation, you may notice droppings or things like chewed wires. If your home has mice, they may be found in places where food is kept or in attics.

    Frequently Asked Questions About Pest Control in Windsor

    What are some causes of 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 foundation crack or broken screen. Some are drawn by food, either actual food sitting out or trash left out in the open. Others are searching for water, either standing water on your property or puddles inside from leaky pipes.

    What are some steps I can take to prevent pest infestations?

    One thing you can do to prevent pest infestations is seal off possible entrances into your house. These include things like cracks in your siding or foundation. Second, avoid leaving food out for pests. This includes keeping food in sealed containers as well as not leaving trash out. Third, reduce standing water in and around your house. Try to reduce places where water can collect outside, and repair leaks inside.

    When should I hire an exterminator?

    Any time you see signs of pests in your Windsor home—such as nests, droppings, signs of damage, or the pests themselves—you should call an exterminator. If your home has had recurrent or seasonal pest infestations, we suggest reaching out to a local pest control company to set up annual pest management services.

    Do I need to worry about my pets during or after pest control?

    Your pest control professional will let you know how far your pets need to be kept away from treated areas, and for how long. Some pesticides are non-toxic or have low toxicity, but as a general rule you'll be asked to keep pets out of the area during and for some time after application.
