Questions to Ask Before Hiring a Pest Control Service in Denver

Poor pest treatment, contamination of the environment, exposure to toxic chemicals, and the extra cost of a new treatment are the risks you run whenever you attempt a DIY pest control solution. It is wise to hire a pest control specialist in Denver who is conversant with contemporary pest application methods and established standards to arrest a pest infestation in your home or office. However, bear in mind that some individuals posing as pest control specialists in the city lack the requisite skill and experience to do the work.

As a result, homeowners should always ask the professional they intend to hire the following questions to determine if they are competent and experienced enough to do the work:

Are You Licensed to Practice as an Exterminator in Denver?

Denver exterminators are not required to obtain a locally issued occupational license to provide their services to members of the public. However, any exterminator that intends to use or supervise the use of pesticides in eliminating pests from a customer's home or property must obtain the appropriate license and certification for such work from the Colorado Department of Agriculture. Applying pesticides without holding the appropriate license or certification may attract civil penalties for offenders. The maximum penalty shall not exceed $1,000 per violation, except where the penalty is doubled by a court after determining that the offender has committed the same crime a second time. To avoid civil penalties, exterminators in the city are encouraged to contact the Colorado Department of Agriculture's Pesticide Applicator Coordinator at (303) 869-9063 to find out about the licensing and certification process.

The Colorado Department of Agriculture issues several types of pesticide applicator licenses to interested persons. These license types include:

  • Qualified supervisor license: For anyone who wishes to evaluate pest problems, recommends pest controls using pesticides or devices, mixes, loads, or applies any pesticide, sells any application services, and operates devices without any type of supervision
  • Certified operator license: For anyone who intends to be using restricted-use pesticides without the on-site supervision of a qualified supervisor
  • Private applicator license: For individuals who use or supervise the use of a restricted-use pesticide to produce an agricultural commodity on property owned or leased by the applicator or the applicator's employer
  • Commercial applicator license: for individuals, other than a private applicator, who engages in the business of applying pesticides for hire

To obtain any of the aforementioned pesticide applicator licenses, interested persons must first pass one or more licensing examinations administered by the Department. Note that the examination type is typically determined by the category of license the individual intends to obtain. For more information on exam types, registration, and schedule call (303) 869-9063.

After successfully completing the appropriate exam, applicants can now proceed to applying for the pest applicator license they want. Applicants who wish to apply for either a qualified supervisor or certified operator license can do so on the same online portal, while those interested in obtaining a private applicator license can do so on a different online portal. Although the Department has stopped paper applications, applicants who may not be able to use the online portal can still request paper applications. Applicants who have questions concerning the licensing portals or paper application can contact the Program Coordinator at (303) 869-9063. Regardless of the application process that is utilized, applicants must provide accurate information and pay the appropriate licensing fees for their application to be considered.

In addition to obtaining an appropriate pesticide applicator license and certification, exterminators who apply or supervise the use of restricted-use pesticides must also be certified as private or commercial applicators by the Environmental Protection Agency (EPA). This is typically performed based on Federal Certification Standards and applicants can obtain a private applicator certification after demonstrating a practical understanding of agricultural pest problems and treatment strategies, as well as correct pesticide storage, use, handling, and disposal. Similarly, applicants can obtain a commercial applicator certificate after showing that they understand basic pesticide use and safety, as well as at least one specialty application area. Applicants can contact the EPA through email or fill out this online form for more information on Federal Certification Standards.

Are You Registered with the Colorado State Pest Control Association?

A poor pest control service exposes you to a variety of liabilities including health problems, property damage, and potential court cases. As a result, it is not only important that you hire an experienced and competent professional, but also an individual that is a member of a state-recognized pest control association. Professionals who are members of a pest control association often comply with the industry standards, state pesticide regulations, and the EPA guidelines, consequently reducing the possibility of mistakes during the job.

Most pest control professionals in Denver are members of the Colorado Pest Control Association, a state-wide organization providing education, training, communication and cooperation; to enhance the positive industry image through community relations and to monitor and participate in legislative and regulatory advocacy. For more information on the benefits of hiring a member of the Colorado Pest Control Association call (800)678-6722. Interested persons can find pest control professionals who are members of the Colorado Pest Control Association by visiting the association's website or on a third-party website maintained by the National Pest Management Association (NPMA).

How Much Do You Charge for Pest Control Services and Why?

The cost of a pest control service in Denver is influenced by a variety of factors. These include the size of the affected area, the type of pest control method to be used, and how frequent the pest treatment will be administered. While these factors typically influence the cost of a pest control service in the city, homeowners should be wary of professionals that charge ridiculous prices by claiming that the pest infestation is too much or that they are going to use a different pest control method for the job.

To avoid falling for these tricks, homeowners should always speak to at least three different exterminators whenever they are in need of a pest control service. It is good to invite each professional to the affected area as this will enable them to assess the severity of the pest problem. Homeowners should also ensure that each exterminator submit a written estimate for the job after inspecting the area. By getting and comparing these estimates, homeowners will be able to determine the actual cost of the pest control service they need.

Do You Comply with Denver Regulations for Pesticide Application?

Although there are no specific pesticide regulations in Denver, professionals who intend to use or supervise the use of pesticides in the city may be required to comply with the state's guidelines. The Colorado Department of Agriculture is responsible for carrying out the administration and enforcement of the state's Pesticide Act. Some requirements of the Colorado Pesticide Act include the mandatory registration of every pesticide product to be used across the state, application for a state permit to use certain pesticide products, prohibition of the use of a pesticide product on which a written cease and desist order was issued, and compulsory notification of customers of the potential side effects of a pesticide product before use. Note that using a pesticide product in a manner that is not in accordance with the state's Pesticide Act may lead to the suspension of the professional. For more information concerning the state's Pesticide Act, contact the Colorado Department of Agriculture at (303) 869-9063

What Type of Pest Control Method Are You Using?

Pest control methods refer to any treatment or elimination solution used to rid your home or property of pests. While you can initiate a simple pest control method in your home, it is always in your best interest to hire a professional to accurately identify the pest problem and select the best pest control method to use. Depending on the pest problem in your home, exterminators can choose any of the following pest control method listed below:

  • Organic Pest Control: In dealing with pest infestations, this control method focuses on the use of natural compounds such as spinosad, pyrethrin, neem oil, diatomaceous earth, bacillus thuringiensis, or sulfur rather than man-made chemicals such as pesticides. Among the organic pest management options are:
    • Wondercide All-Purpose Organic Home & Garden Insect Control
    • EcoRaider Ant & Crawling Insect Killer
    • EcoSmart Ant & Roach Killer
    • Verdana Cold-Pressed Organic Neem Oil
    • Essentria IC3

In addition, organic pest control strategies also involve the use of trap crops, pheromone traps, and the release of beneficial insects.

Biological Pest Control: This involves the use of biological control agents such as parasites, pathogens, and predators because of their ability to effectively kill and keep pests at bay. Biological pest control method is a proactive strategy in which action is taken prior to pest presence or at the first sign of their presence. For example, the introduction of Lacewings (Chrysopa spp.), a predatory insect that feeds on or lays eggs in, the insects you want to get rid of, can help reduce the numbers of pests exponentially after their first outbreak. Note that this control method can be counterproductive if it is not handled by a specialist.

Physical and Mechanical Pest Control: This strategy involves the use of devices and physical barriers to both eliminate and reduce the spread of pests. Common means to control pests include tillage, flaming, flooding, soil solarization, and row covers, while devices such as screens, fences, barriers, traps, and mulches are used as mechanical solutions to pest problems.

Chemical Pest Control: This control method involves the application of pesticides as pest treatment. Although this method works faster, it is considered a more dangerous way to eliminate pests. This method can result in severe health problems if the pesticide is not used properly. As a result, pesticide applications should be left to licensed professionals alone. A qualified pest control professional understands not only when to administer pesticides, but also the type of pesticide required for a specific pest infestation. Common chemical pesticides used by exterminators include:

    • CimeXa Insecticide Dust
    • Suspend SC Concentrate
    • Termidor SC Concentrate
    • BioAdvanced 3-in-1 Insect Disease & Mite Control

Having seen that it is safer to hire a competent hand for pest control services, interested persons should not hesitate to get recommendations from trusted families, neighbors, and associates. Interested persons can also visit third-party websites such as Better Business Bureau for qualified pest control workers. Here, you can even check for reviews and testimonies on the professional you intend to hire.

While most pest control firms in Denver provide all three types of pest control services, it is in your best interest to choose a professional who specializes in the type of pest services you need.

According to the US Bureau of Labor Statistics, four fatal and 2,820 nonfatal on-the-job injuries among pest control workers were registered in 2020 alone.
