How To Choose a Pest Control Company

Choosing the best pest control expert for you is important. Important factors can include a company's qualifications, its treatment methods, experience and reviews, and of course the cost of services.

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 those that supervise them must be certified at the state level. The EPA sets minimum standards of competency, but all Maryland pesticide applicators should be licensed through the proper state regulatory agencies.

  • Is the company a member of any professional organizations?

    A pest control company can receive optional certifications from trade organizations like QualityPro in order to support its methods and standards. One particular certification is the GreenPro Service Certification, which is awarded to any company that can demonstrate that its methods are more environmentally friendly. These companies also need to maintain certain employee training standards.

    Pest control companies can also hold membership in various professional organizations. Becoming a member of an organization such as the National Pest Management Association (NPMA) or a state-level organization gives companies access to education and resources, as well as a network of professionals with whom to compare best practices. Joining organizations like these is not mandatory, but it can help indicate that a company follows industry best practices.

Professional Experience and Specialties

Looking at a pest control company's website can tell you how long it has been in business and what kind of pests it specializes in exterminating. Online reviews can also give you some insight into a company's experience dealing with a certain type of pest. If you're unable to find this information online, you can try contacting the company directly.

  • Reviews and Recommendations

    You can look up a company's rating and reviews 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 Maryland licensing board.

  • Cost of Services and Guarantees

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

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

Safety and Treatment Methods

When 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

    All pesticides that will be used (except those that are determined to be of minimal risk) must be registered with the EPA. Your pest control provider should be able to provide information on all the pesticides that they are using. They should inform you whether the pesticides are low toxicity or non-toxic, and if not, what safety precautions they plan to take.

  • Treatment Methods

    Many companies will begin with more eco-friendly treatment options before using harsh pesticides, following a framework called Integrated Pest Management (IPM). When using IPM, the following steps are taken:

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

Common Household Pests in Frederick

Certain pests are more prevalent in Frederick, and these are the ones you should keep watch for. Some of these include the following:

  • Flies: You might find flies around sinks or in places where you keep food. Flies might get into your house in Frederick throughout the year, but they're particularly common in warmer weather.
  • Termites: Termites often come into your home from nearby piles of firewood, mulch, or rotting wood. If left untreated, they can do a significant amount of damage and cost you hundreds or thousands of dollars in repairs.
  • Ants: Whether smaller soil ants or larger carpenter ants, these pests are found in most parts of Maryland. Carpenter ants can cause more problems than their smaller counterparts by causing damage to your house.
  • Mice: If you have mice, you might notice droppings around your house, or things like chewed wires. You can often find mice in places where food is stored or in attics.
  • Bed bugs: Bed bugs may be found throughout Maryland and can cause big problems if left untreated. Because infestations of bed bugs are often difficult to get rid of, we recommend hiring a professional exterminator as soon as you discover the problem. These pests can infest wallpaper, bedsheets, furniture, and more.

Frequently Asked Questions About Pest Control in Frederick

What are some causes of pest infestations?

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

What are some steps I can take to prevent pest infestations?

There are several 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, avoid having standing water in or around your house. Fix leaks inside and eliminate standing water sites outdoors. Finally, seal off potential pest entrances into your house, including siding or foundation cracks.

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

Generally it's recommended that you hire a pest control technician about once annually. If your home has an active infestation, you will need pest control to come out more frequently. Ultimately, your pest professional will be the person best-equipped to recommend a treatment schedule for you.

Will pests come out after spraying for them?

You could feel like you're seeing a greater number of pests around your house in the days after pest control treatment. This is because living pests are being flushed from their hiding places deep in your home, or you may be seeing more dead pests. If pest activity hasn't started to go down in a week or two following treatment, reach out to your Frederick pest control professional to see if more treatment is required.
