    How To Choose a Pest Control Company

    The most important step is choosing the best pest control company for the job. A company's qualifications and treatment methods are important to consider, as are its years of experience and reputation in customer reviews. Of course, you will also want to consider cost.

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

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

      The United States Environmental Protection Agency (EPA) has established minimum competency standards for pesticide applicators, but licensure is taken care of at the state level. All pesticide applicators and their supervisors in California must be licensed through the proper state regulatory agencies.

    • Is the company a member of any professional organizations?

      A pest control company can optionally apply for additional certifications from QualityPro or similar trade organizations to back up its standards and methods. One particular certification is the GreenPro Service Certification, which is granted when a company can demonstrate that its methods are more environmentally friendly. These companies also need to maintain certain training standards for employees.

      Pest control companies can also become members of professional organizations. While not mandatory, membership in organizations such as the National Pest Management Association (NPMA) or state-level organizations help show a company's reputability. After joining an organization like the NPMA, a company receives access to resources, education, and a network of other professionals with whom to compare best practices.

    Professional Experience and Specialties

    A company's years in business can indicate how much experience it has dealing with pests in your area. You can also look at its website or read customer reviews to decide whether it has the right kind of experience handling the species of pests you are dealing with. If this information can't be found online, getting in touch with a company representative is a great way to learn more.

    • Reviews and Recommendations

      You can look at a company's rating and reviews on the Better Business Bureau (BBB), check out local review sites and social media to hear what other people are saying, or verify its license standing via the California licensing board.

    • Cost of Services and Guarantees

      Pest control costs can vary based on things like the type of pest being treated, the size of your house, your location, and other factors.

      When considering the cost of services, you should first look into whether a company provides free on-site estimates as part of its process. This can help determine whether the company fits into your budget. Also take into account a company's guarantees: If the problem is not resolved, or if it returns, does the company provide additional treatment until the issue is resolved satisfactorily?

    Safety and Treatment Methods

    Your choice of pest control company might be influenced by how environmentally friendly a company's practices are, in addition to how safe its methods are around your family and pets.

    • Safety

      Your pest technician should use low toxicity or non-toxic pesticides whenever possible. If they plan to use pesticides that don't fall into one of these categories, your technician should explain what safety precautions they will put in place to protect your family, your pets, and you. All pesticides that pose more than a minimum risk are required to be registered with the EPA.

    • Treatment Methods

      Many companies have begun using more natural treatment methods before, or in place of, harsh chemical pesticides. Some use a program called Integrated Pest Management (IPM). The steps of IPM are as follows:

      1. Figure out what pests are causing the problem and determine if immediate action is required.
      2. Determine the best and safest course of action.
      3. Use a combination of biological, cultural, physical, and mechanical controls to manage the pest problem.
      4. Use chemical controls only when absolutely necessary, and always with other techniques for effective long-term pest management.
      5. Assess the outcome and implement additional pest control as needed.

    Common Household Pests in Fairfield

    In Fairfield, some species of pests are more common than others. This list includes the following:

    • Beetles: Across the U.S. and in Fairfield, there are a variety of beetle species that could cause problems. Many beetles are harmless, but others can do damage by eating wood, carpeting, and more.
    • Termites: If termites get out of hand, the result could be hundreds or thousands of dollars in damage. Termites often get inside via nearby piles of rotting wood, firewood, or mulch.
    • Ticks: If you live near forests or areas with dense vegetation, or near a body of water, you may be at greater risk of a tick infestation. Ticks can spread diseases like Lyme to you and your pets.
    • Spiders: These pests prefer dark and damp places and are commonly found in attics.
    • Bed bugs: Bed bugs can be found throughout California, and they can lead to serious problems if left untreated. Because bed bug infestations are tricky to get rid of, we recommend getting professional extermination as soon as you discover the problem. These pests can infest furniture, wallpaper, bedsheets, and more.
    • Mice: Some common signs of mouse activity include chewed wires and droppings around your house. Mice are commonly found in attics or in places where food is kept.

    Frequently Asked Questions About Pest Control in Fairfield

    What causes pest infestations?

    Pest infestations happen when pests enter your home looking for something, generally food, water, or shelter. Pests might be looking to eat food or trash that is sitting out. Some might also be drawn to standing water outside (from rain collecting in a particular area) or inside (from leaky pipes). They might also enter your house simply looking for shelter. They can get in through weak spots such as foundation cracks or broken screens.

    How can I prevent pest infestations?

    One method for preventing pest infestations is to seal off possible entrances into your home. This includes 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. Lastly, reduce standing water in and around your home. Work to reduce places where water collects outside, and fix leaks inside.

    How frequently do I need to hire a pest control professional?

    It is generally recommended that you hire a pest control technician about once a year. If your home has an active infestation, you will need to hire a pest control professional more often. Ultimately, your pest professional is the person best-equipped to recommend a treatment schedule for you.

    What do I need to do before pest control services?

    Before a pest professional comes to your home, check and see if they want you to clean around your home, including in areas where you've seen pests. Some pest professionals may prefer to see your house as-is.

    If you are asked to clean, focus on making sure all paper goods and trash are out of the affected areas (as pests may hide in these items), and that food is stored away so that it does not become contaminated with pesticides. You might also want to remove plants from the affected areas. Also make sure to block off areas to be treated so that children and pets stay out until it is safe. If the problem needs more intensive pest control, such as fumigation, make sure you follow your pest professional's instructions closely.
