How To Choose a Pest Control Company

There are several things that you can weigh when selecting the best pest control professionalfor you. You may consider a company's qualifications and methods of treatment in addition to its years of experience and customer reviews. And of course, there's the cost of services to consider.

Below, we dive into detail on each of these factors.

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

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

  • Is the company a member of any professional organizations?

    Pest control companies can obtain optional certifications from QualityPro or similar trade organizations. While not required, they can help you assess the quality of a company's products. For example, the GreenPro Service Certification indicates comprehensive and effective pest control methods that are safer for people and the environment.

    Pest control companies can also be members of certain professional organizations. Holding membership in organizations such as the National Pest Management Association (NPMA) or state-level organizations is not mandatory, but helps confirm that a company follows industry best practices. When a pest control company joins the NPMA, it gains access to education, resources, and a network of pest professionals with whom to discuss practices and methods.

Professional Experience and Specialties

You can get some insight into a company's experience level by looking at how long it has been in business. The company's website and local reviews can also tell you whether a company has the experience needed to deal with the specific species of pests invading your home. You can reach out to a representative directly to learn this information if it is not available online.

  • Reviews and Recommendations

    You can verify a company's legitimacy using the Better Business Bureau (BBB) and social media or local review sites. You can also check with Oregon's licensing board to see the status of a company's license.

  • Cost of Services and Guarantees

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

    You can take into consideration whether a company offers free on-site estimates (to determine if it fits 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

Keeping yourself, your family and your pets safe is an important concern when choosing a pest control provider. You may also prefer a provider that uses eco-friendly pest management treatment methods.

  • Safety

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

  • Treatment Methods

    Many companies are now exploring more environmentally friendly pest control solutions that can be used before (or in place of) chemical pesticides. Many follow 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. Manage the pest problem using a combination of biological, cultural, physical, and mechanical controls.
    4. Employ chemical controls only when required, and always in combination with other controls for effective long-term pest management.
    5. Assess the outcome and provide additional pest control as needed.

Common Household Pests in Gresham

In Gresham, there are some pests that are more common than others. This list of pests includes the following:

  • Ants: Whether larger carpenter ants or smaller soils ants, these pests can be found in most of Oregon. Carpenter ants can pose a bigger problem than their smaller counterparts because they can do damage to your house.
  • Bed bugs: Infestations of bed bugs can be very difficult to eliminate, so we strongly recommend calling a local exterminator as soon as possible. Bed bugs are found throughout Oregon, and can infest not only your bedsheets, but also other furniture and even your wallpaper.
  • Spiders: Spiders usually prefer moist, dark places and are often found in basements or attics.

Frequently Asked Questions About Pest Control in Gresham

What are some causes of pest infestations?

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

What are some things I can do to prevent pest infestations?

There are certain steps you can take to help prevent pest infestations. First, don't leave food out. Make sure food is stored in sealed containers, and don't leave trash sitting around.

Next, try not to have standing water in or around your house. Repair leaks inside and eliminate standing water sites outside. Finally, seal off any possible pest entrances into your home, including foundation and siding cracks.

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

You should consider hiring a pest control professional any time you identify signs of pests in your Gresham home. You might see droppings, nests, pest damage, or even the pests themselves. If you've had seasonal or recurrent pest infestations, we recommend annual preventive pest management.

What is the importance of preventive pest control?

If you get pests in your home, you might end up spending a large amount of time and money ridding your house of them, and potentially recovering from illness or damages they cause. Preventive pest control can help stop things like this from happening in the first place.
