    How To Choose a Pest Control Company

    The first step is selecting the right pest control company for the job. 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 dive into detail on each of these factors.

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

      While the United States Environmental Protection Agency (EPA) has established minimum standards of competency for pesticide applicators, licensing is taken care of at the state level. All pesticide applicators (and those who supervise them) in California should be licensed by all the necessary state regulatory agencies.

    • Is the company a member of any professional organizations?

      One certification that pest control companies can earn is the GreenPro Service Certification, which requires a company to show that its practices are more environmentally friendly and that its employee training is up to date. QualityPro and similar trade organizations also offer other certifications. While not required, these can help show that a company is reputable.

      A pest control company can also hold membership in professional organizations. When a company joins an organization like the National Pest Management Association(NPMA) (or a state-level organization), it receives access to resources, education, and a network of other pest experts with whom to compare treatment methods. This can give you extra peace of mind that a company follows industry best practices.

    Professional Experience and Specialties

    The amount of time that a company has been in business can give you some insight into its experience dealing with the pests that live in Napa. Customer reviews or the company's own website can also inform you whether it has the experience needed to handle your specific pest problem. 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

      You can view a company's reviews and rating on the Better Business Bureau (BBB), explore local review sites and social media to learn what homeowners near you think, or verify its license standing through the California licensing board.

    • Cost of Services and Guarantees

      For many people, cost is one of the main deciding factors when hiring for pest control. Cost can be influenced by factors like your location, the size of your house, and the type of pest being treated.

      You can think about whether a particular company offers 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 its treatment doesn't resolve your pest problem, it will continue to come back until it does.

    Safety and Treatment Methods

    Your choice of pest control company might be affected by how environmentally friendly a provider's practices are, as well as how safe its methods are around your family and pets.

    • Safety

      Make sure to ask your pest control technician if they plan to use low toxicity or non-toxic pesticides, and if not, what kind of precautionary measures they plan to take. All pesticides that are not considered minimum-risk chemicals need to be registered with the EPA. Your pest control provider will be able to supply information about all of the pesticides that they are going to use.

    • Treatment Methods

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

      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, physical, biological, and cultural controls to manage the pest problem.
      4. Use chemical controls only when absolutely necessary, and always in combination with other solutions for effective long-term pest management.
      5. Evaluate outcomes and implement additional pest control as needed.

    Common Household Pests in Napa

    Not all pests are equally common in Napa. Some species that you should be on the lookout for are these:

    • Flies: You may find flies around sinks or in places where you keep food. Flies can get into your house in Napa throughout the year, but they're particularly common in warmer weather.
    • Bed bugs: Bed bugs are found throughout California, and they can lead to major problems if left untreated. Because infestations of bed bugs are often tricky to get rid of, we recommend getting professional extermination as soon as you discover the problem. These pests can infest wallpaper, bedsheets, furniture, and more.
    • Mice: Some telltale signs of mouse activity include chewed wires and droppings around your house. Mice tend to frequent attics or areas where you keep food.
    • Spiders: You may encounter spiders in your attic or other moist, dark places. Even though most species of spider are harmless to humans, you don't want a spider infestation in your house.

    Frequently Asked Questions About Pest Control in Napa

    What causes pest infestations?

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

    How can I prevent pest infestations?

    One method for preventing pest infestations is to seal off potential entrances into your house. This includes things like cracks in your foundation or siding. Next, try to avoid leaving food out for pests. This includes keeping food in sealed containers and not leaving trash out. Third, reduce standing water in and around your house. Work to reduce places where water can collect outside, and fix leaks inside.

    When should I hire a pest control professional?

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

    Do I need to clean my house after pest control services?

    We recommend checking in with your pest control technician while they are at your house, as the answer can vary depending on what treatments are done. After application of pesticides, you might notice a lingering smell that should dissipate over time.

    In many cases, dusting, vacuuming, and wiping down certain surfaces will be appropriate after pest control. However, make sure to not wipe away chemical barriers, and avoid touching any traps unless you are explicitly told to do so. After the pest control process, continue to keep your home clean. Avoid letting trash pile up, take care of spills and leaks promptly, and so on. This will help keep pests from coming back.
