Maryland pesticide application records: what the rule requires (COMAR 15.05.01.12)

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 (Maryland Department of Agriculture).

What the record must include

Name of applicator
Date of application
Site treated and pest to be controlled
Description of the area or structure treated, with square, cubic or linear footage when the label specifies those measurements
Address of the treated property
Name of the owner or tenant
Common name and EPA registration number of each pesticide
Rate and concentration
Total amount of pesticide used
Type of equipment used
Time of day of application
Wind direction and estimated speed, except for baits in bait stations or applications in, or within 3 feet of, a structure

How long to keep it

2 years. Must be available to the department immediately on request.

What the customer gets

When the pesticide is applied, or when the customer signs the contract, give the customer written information: licensee name, Maryland pesticide business license number, licensee phone, Maryland Poison Center phone and the common name of the pesticide or active ingredient.
It must also include a copy of the product label, or of its precautionary statements section, or a precaution sheet approved in advance by the department.
If the customer asks, the licensee must give advance notice of an application.

Termites, fumigation and other cases

The pesticide-sensitive individuals list and the posting-sign rule apply to lawn/ornamental and mosquito categories, not to structural pest control.

How PestSheet covers it in Maryland

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

Target pest
Areas or sites treated
EPA registration number
Rate or dilution
Amount applied
Application method

For exterior applications, it also asks for:

Weather (wind, temperature)

Also:

Written information for the customer at application or contract (COMAR 15.05.01.16), with links to the EPA labels (Pro to share).
Reminds you to keep records at least 2 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 COMAR 15.05.01.12 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 Maryland's school IPM notification rules (COMAR 15.05.02).
