How To Choose a Pest Control Company

The most important step is hiring the right pest control company for the job. Some things you might consider include licensing and qualifications, treatment methods, years of experience, customer reviews, and cost.

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 certified at the state level. The EPA does set minimum standards of competency, but all pesticide applicators in California should be licensed through the proper state regulatory agencies.

  • Is the company a member of any professional organizations?

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

    Pest control companies can also become members of various professional organizations. Becoming a member of an organization like the National Pest Management Association (NPMA) or a state-level organization gives companies access to resources and education, and a professional network to compare best practices with. Membership in one of these organizations is not required, but it can help indicate 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 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 handle your specific pest problem. If you cannot find the answers to your questions online, calling a representative is a great way to learn about the company's areas of expertise.

  • Reviews and Recommendations

    You can look at a company's rating and reviews on the Better Business Bureau (BBB), explore local review sites and social media to see what others in your area have to say, 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 services. Cost can be affected by factors like your location, the size of your house, and the type of pest being treated.

    You can think about whether a certain company offers free on-site estimates (to determine if it fits your budget), and what kind of guarantees it provides. Often, a company will guarantee that if your pest problem isn't fixed by its treatment, it will continue to treat until it is.

Safety and Treatment Methods

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

  • Safety

    Ask your pest control technician if they are going to use low toxicity or non-toxic pesticides, and if not, ask what precautionary measures they plan to use. Any pesticide that poses greater than minimum risk must be registered with the EPA. Your pest technician should be able to supply information about all of the pesticides that will be used in your home, and how safe they are around people and pets.

  • Treatment Methods

    You can ask if your technician will start with more natural and lower-toxicity options before using harsher chemicals.

    Many companies are using Integrated Pest Management (IPM) to reduce personal or environmental risk when treating pest infestations. The steps of IPM are as follows:

    1. Figure out what pests are causing the problem and assess whether 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 along with other methods for effective long-term pest management.
    5. Assess the outcome and implement additional pest control as needed.

Common Household Pests in Westminster

Not all pests are equally common in Westminster. Some species that you should be wary of are these:

  • Snakes: Snakes often enter houses looking for food, and once inside they tend to prefer cool, dark, and damp spots. While the majority of snakes are harmless, most people don't want their family, their pets, or themselves to take that risk.
  • Spiders: Spiders usually prefer moist, dark places and are often found in attics.
  • Bed bugs: Bed bugs are found throughout California and can lead to major problems if left untreated. Because infestations of bed bugs can be hard to get rid of, we recommend hiring a professional exterminator as soon as you discover the problem. Bed bugs can infest furniture, bedsheets, wallpaper, and more.

Westminster Pest Control FAQ

What causes pest infestations?

Pest infestations happen when pests enter your home looking for something, generally food, water, or shelter. Pests might seek out and eat food or trash left sitting out. Some may also be drawn by standing water collecting outside (from rain collecting in one spot) or inside (from leaky pipes). Pests might also come into your house looking for shelter. They can get in through places such as foundation cracks or broken screens.

How can I prevent pest infestations?

One method for preventing pest infestations is to seal off potential 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 and not leaving trash out. Finally, reduce standing water in and around your house. Find ways to reduce places where water collects outside, and repair leaks inside.

How do I know when to hire a pest control professional?

Any time you notice signs of pests in your Westminster home--things like droppings, nests, signs of damage, or the pests themselves--you should contact your local pest professional. If you've had seasonal or recurrent infestations, we suggest reaching out to a local pest control company to request annual pest management services.

Why is preventive pest control important?

If you get pests in your home, you might find yourself spending a good deal of time and money ridding yourself of them, and potentially recovering from illness or damages they have caused. Preventive pest control can stop things like this from happening in the first place.

Is pest control safe around my pets?

Your pest control professional will let you know how far your pets should be kept away from treated areas, and for how long after treatment. Some pesticides are non-toxic or have low toxicity, but in the vast majority of cases you'll be asked to keep pets out of the area during and for some time after treatment.
