Pesticide Sensitive Facts and Registry

Facts about the Pesticide Sensitive Registry and Mosquito and Other Public Health Pesticide Applications

Mosquito spraying is performed by city, county or other local authorities or by companies they hire under their local authority to protect the health of the people in the community.

If you don't want your property included in the spraying, you must contact those people and ask them to exclude your property from the program if they are able to do that.

Any notification provided to the public during a Public Health Pest Control operation (i.e.: mosquito treatment applications) by municipalities and/or commercial applicators, is done as a courtesy to those requesting, not because it is a state law requirement.

The registry maintained by the Colorado Department of Agriculture does not pertain to mosquito spraying, or any pesticide applications other than those made to control pests of lawns, trees & shrubs.

The pesticide sensitive registry is for people who have or can obtain documentation of sensitivity to pesticide products from a licensed Colorado physician.

To be placed on the registry a certificate must be signed, by a physician licensed to practice medicine in the state of Colorado, stating that you have a medical condition that makes you sensitive to pesticides.

The registry does not prevent application of pesticides but only requires that commercial applicators (like lawn care companies) notify people on the registry 24 hours before an application is made to abutting property (property that touches yours) so that you can leave for a period of time or make other preparations for the application.

The law that outlines the requirements of the Pesticide Sensitive Registry can be found under 35-10-112 of the Pesticide Applicators Act, which can be accessed through the Plant Industry Laws & Regulations page.

If you have questions regarding the date, time, or area of an upcoming public health pest control application (i.e.: mosquito control) you should contact your local health department.
