Colorado pesticide application records: what the rule requires (8 CCR 1203-2, Part 6.03)

Not legal advice. This summarizes our research of the official rule, checked October 2, 2026. Rules change and may require more than what is listed here: confirm with the official text or with the agency (Colorado Department of Agriculture (CDA)).

What the record must include

Name and address of the customer, and location of application if different
Specific target pest
Site or structure treated
EPA registration number of the product
Dilution rate (or "no dilution", "aerosol" or "RTU")
Application rate per area or volume (or "crack and crevice")
Carrier, if other than water
Date and time the application started or stopped, accurate to within half an hour ("A.M."/"P.M." is not enough)
Name and license number of the person who made or supervised the application

Also for restricted use pesticides (RUP)

If an applicator technician applies it, the names of both the technician and the on-site qualified supervisor

How long to keep it

3 years. Counted from the date of application; kept at the address on the business license.

What the customer gets

At the time of application, leave each customer a printed or legibly handwritten notice with the name of each pesticide, the date applied and the label precautions needed to protect people, animals and property.
If the customer is not the occupant, the occupant gets the same notice.
Electronic notices are allowed only with the customer's or occupant's written request kept on file.
In multi-unit buildings with no owner or agent on site, post a written notice at the main entrance to treated interior common areas (not electronic).

Termites, fumigation and other cases

Pesticide-sensitive registry: in multi-unit dwellings, registered residents must be told the date and approximate time of treatment, with attempts at least 24 hours before.
Termite records add more items (preconstruction square footage and times; post-construction diagram, contract and supervisor signature).
Bed bug reports to the landlord within 24 hours of inspection; kept 3 years.

Recent changes

The current rules (8 CCR 1203-2) took effect on September 17, 2025.

How PestSheet covers it in Colorado

Before you complete a visit for a client in Colorado, PestSheet checks that these fields are filled in:

Applicator license or certification number
Target pest
Areas or sites treated
EPA registration number
Rate or dilution

Also:

Written information for the customer at the time of application (8 CCR 1203-2 Part 10.04) (Pro to share).
Reminds you to keep records at least 3 years.
Export the records of any period as PDF or CSV for an inspection (Pro).

The client's name and address, the service date and start time, and the applicator's name are always recorded. The app uses the 8 CCR 1203-2 Part 6.03 template. It doesn't check items the app doesn't record (for example active ingredients or equipment); those remain your responsibility.

What we could not confirm

We could not confirm on the Secretary of State's official site that no later version of 8 CCR 1203-2 exists.
