Pesticide Applicator Licence Check: what it covers

Quick answer

In Colorado, the Department of Agriculture licenses anyone who applies pesticides for pay as a Commercial Pesticide Applicator, and each commercial business needs a Qualified Supervisor. A caller in Boulder should ask for the business and applicator details at booking and check them with the Department before work starts.

The licence is the simplest check a caller can make, and it is the one most often skipped. A pest control technician who applies a product for pay in Colorado must hold a licence from the Colorado Department of Agriculture. A caller who asks for the details at the start of the job, and checks them later if they want to, has a clear answer to the question of who is doing the work.

This page explains what to ask for and where to check it. It does not print any licence number, because the technicians’ details are given on request by phone, for their privacy. It also does not describe the exam or the training in detail, because the sourced material for this site does not do so, and the Department is the place to confirm those.

Our process

How our pesticide applicator licence check visit works

  1. Ask at booking

    When you book, ask for the business name and the name of the applicator who will do the work. Ask for the licence details to be given on request by phone, and write down the name and the date.

  2. Check at the door

    The technician should be able to show the applicator licence and the business licence. If the work is supervised, ask for the supervisor’s name and check that it matches the business.

  3. Check with the Department

    The Colorado Department of Agriculture licenses commercial pesticide applicators and businesses. The Department can confirm whether a licence is current, and that is the check to use.

  4. Ask for the label

    Ask to see the label of any product that will be applied. The label gives the product’s use, its safety rules and its re-entry time, and it is the document the applicator follows.

  5. Keep the record

    Keep the booking note, the invoice, the report and any licence detail given. If something goes wrong, the record shows what was agreed and who did the work.

What does a Colorado pest control licence cover?

A Colorado Commercial Pesticide Applicator licence covers an individual who applies pesticides for pay, and a business that does so must have a Qualified Supervisor and follow the Department’s rules. The licence is the document to ask for, and the Department is the place to check it.

The Department of Agriculture licenses anyone who applies pesticides for pay, which covers most pest control technicians. The licence sets out what the holder may apply, and the holder is expected to follow the label and the Department’s rules. A caller does not need to know the details of the rules to ask whether the technician holds the licence.

The business is licensed separately, and it must have a Qualified Supervisor. The supervisor is the person responsible for the business’s pesticide work under the rules. The caller can ask for that person’s name, and the business should be able to give it.

What should I ask for on the phone?

Ask for the business name, the applicator’s name and licence details, the supervisor’s name, and the product that will be used. Those five answers tell you who is doing the work and what is going into the building.

The licence details are given on request by phone. This site does not print them, and it does not hold them, because the technicians’ privacy is protected. The call should end with a clear answer, and if a number is not given, the caller can ask for it again in writing before work starts.

The product name and the label are part of the same conversation. A business that is confident in its work will name the product and show the label. A caller who receives a vague answer should ask again before any application.

How do I verify a number with the state?

Use the Colorado Department of Agriculture to confirm that a licence is current. The Department licenses both the individual applicator and the business, so both numbers can be checked.

A check takes a few minutes with the number in hand. The caller confirms the licence is current, that the holder’s name matches the technician, and that the business is licensed. If any of those does not match, the caller should not let the work start until it is explained.

This site states only that the Department of Agriculture is the licensing body. It does not describe the Department’s online tools or its forms, because none of those were checked for this site. The Department’s own pages are the source for the current process.

What if the technician cannot show a licence?

Do not let the work start. Ask for the licence details again, check them with the Department, and if they cannot be confirmed, end the booking and keep a note of the conversation.

A technician who is working lawfully should be able to show the licence without delay. A missing licence is a reason to stop, and the caller is entitled to ask why. A note of the date, the name and what was said is useful if the matter is raised with the Department later.

The caller should not be pressured to proceed. A legitimate business will accept a pause to check the details, and a delay of a day or two is a small cost for a clear answer about who is applying a product in the home.

What if the business is new?

A new business still needs its own licence and its own Qualified Supervisor. A caller can ask when the business started and check the licence records with the Colorado Department of Agriculture, whatever its age.

A business that has just started can still be fully licensed. The age of the business does not decide whether it is allowed to apply products, and the licence does. The caller should check the same details, and should not treat a new business as either safer or less safe on that basis alone.

A business with a licence number that does not appear in the state records should not be used. A business that cannot explain the gap should be checked with the Department directly.

FAQ

Pesticide Applicator Licence Check FAQs

Is a licence really needed for every pest job?

In Colorado, anyone who applies pesticides for pay must hold a licence from the Department of Agriculture. Ask the business to confirm its licence and the applicator’s before work begins.

Why are the licence numbers not printed on this site?

To protect the technicians’ privacy. The details are given on request by phone, and the Department is the place to check any number a caller receives.

What if the number I am given does not check out?

Do not let the work start. Ask the business to explain, and contact the Department of Agriculture with the number and the details you have.

Does a licence guarantee the work?

No. A licence shows who is authorised to apply a product, and it does not guarantee a result or a particular quality of work. The work itself is between the homeowner and the company that performs it.

Do I need to keep the licence details after the visit?

Yes. Keep the details with the booking note and the report, so that the record shows who did the work and under what licence.
