    How To Choose a Pest Control Company

    There are a number of things you can consider when selecting the right pest control company for you. The qualifications of and treatment methods used by a company are important to consider, as are its years of experience and reputation in customer reviews. Of course, you also want to consider cost.

    Below, we discuss each of these factors in more detail.

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

      All pesticide applicators, as well as those that supervise them, need to be licensed via the appropriate California regulatory agencies. The United States Environmental Protection Agency (EPA) sets minimum standards of competency, while providing, maintaining, and revoking licensing is handled at the state level.

    • Is the company a member of any professional organizations?

      One optional certification that may be worth looking for is the GreenPro Service Certification. To get this certification, a pest control company must both demonstrate that its practices are more environmentally friendly and uphold certain technician training standards. Companies can earn other certifications from trade organizations like QualityPro to further back up their work.

      There are several professional organizations that a pest control company can be a member of. A pest control company can join state-level organizations as well as national organizations such as the National Pest Management Association (NPMA). While not mandatory, membership in these organizations helps prove a company's reputability and gives it access to resources, education, and a network of other professionals with whom to compare best practices.

    Professional Experience and Specialties

    Looking at how long a company has been in business can help determine how much experience it has dealing with pests in your area. You can also browse its website or read customer reviews to determine whether it has adequate experience with the species of pests you are dealing with. If you cannot find this information online, speaking with a company representative is a good way to learn more.

    • Reviews and Recommendations

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

    • Cost of Services and Guarantees

      Cost is often a deciding factor when choosing a pest control company. Cost may be determined by the type of pest being treated, the size of your house, your location, and other factors.

      Certain pest control companies offer a free on-site estimate to help you match services to your budget. You can also check to see if it offers a guarantee of satisfaction.

    Safety and Treatment Methods

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

    • Safety

      It's important to understand the precautions around pesticides used around your house, for the sake of your family, your pets, and yourself. Your pest control technician should be able to supply information about any pesticides they will be using, whether they are low toxicity or non-toxic, and (if not) what safety measures they have in place. All pesticides (except minimum-risk ones) must be registered with the EPA.

    • Treatment Methods

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

      Many companies now use Integrated Pest Management (IPM) to eliminate pests while reducing personal and environmental risks. 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. Manage the pest problem using a combination of biological, cultural, mechanical, and physical controls.
      4. Use chemical controls only if needed, and always with other solutions for effective long-term pest management.
      5. Evaluate outcomes and implement additional pest control as needed.

    Common Household Pests in Monrovia

    Some specific pests are seen more commonly in Monrovia, and these are the ones you should keep watch for. Some of these include the following:

    • Ants: Whether they are larger carpenter ants or smaller soils ants, these pests can be found in most areas of California. Carpenter ants can cause more problems than their smaller counterparts because they can do damage to your home.
    • Flies: You might see flies around sinks or in areas where you keep food. Flies might get into your house in Monrovia throughout the year, but they're even more common during warmer months.
    • Cockroaches: Cockroaches can be found in many parts of California, though they prefer wetter areas. Cockroaches enter your home through small cracks, and sometimes spread diseases like salmonella.
    • Mice: Telltale signs of mouse activity include chewed wires and droppings around your home. Mice tend to frequent attics or areas where food is kept.
    • Bed bugs: Bed bugs may be found throughout California, and they can cause major problems if left untreated. Because infestations of bed bugs are difficult to get rid of, we recommend hiring a professional exterminator as soon as you discover the problem. These pests can infest bedsheets, wallpaper, furniture, and more.
    • Spiders: Spiders usually prefer dark and moist places and are often found in attics.

    Frequently Asked Questions About Pest Control in Monrovia

    What causes pest infestations?

    Pest infestations happen when pests enter your house looking for something, typically food, water, or shelter. Pests may seek out and eat food or trash that is sitting out. Some might also be drawn by standing water collecting outside (from rain collecting in a particular spot) or inside (from leaky pipes). They might also enter your house simply looking for shelter. They can get in through weak spots like 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 house. These include things like cracks in your foundation or siding. Second, 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. Try to reduce places where water can collect outside, and repair leaks inside.

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

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

    What should I 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 noticed pests. Some pest technicians may prefer to see your house as-is.

    If you are asked to clean, make sure all trash and paper goods are out of the affected areas (as pests may hide in these items), and that you store food securely so that it does not become contaminated with pesticides. It's also a good idea to remove plants from the area. Additionally, block off areas to be treated to keep children and pets out until it is safe. If the problem requires a more intensive type of pest control like fumigation, be sure to follow your pest professional's instructions closely.

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

    We recommend asking your pest control technician this question while they are at your house, as the answer can vary depending on the treatments used. After pesticides are applied, you might notice a lingering smell that will dissipate over time.

    Generally, dusting, vacuuming, and wiping down certain surfaces will be appropriate after pest control. However, make sure that you don't wipe away chemical barriers, and avoid touching any traps unless explicitly told to do so. After pest control, continue keeping your home clean. Don't let trash pile up, take care of spills and leaks promptly, and so on. This helps keep pests from coming back.
