How do I get rid of unwanted pesticides?

The Colorado Department of Agriculture provides a Google Map to help you locate a site for the disposal of pesticides. The map contains contact information for each county. When contacting a county be sure to check residency requirements, as well as what types of pesticides are accepted. A link to CDA's Google Map can be found here.

Within Colorado, the easiest way to get rid of unwanted pesticides is the Colorado ChemSweep Pesticide Disposal Program. Pesticide disposal is an important part of your responsibilities as a pesticide user.

Why Should I Participate?

Unused, unwanted, or banned pesticides are dangerous to keep on your premises. It is smart to participate in a pesticide pick-up program that will lower your liability and the danger these pesticides present to the environment.


  • Using ChemSweep is significantly more economical than disposing of hazardous waste yourself.
  • ChemSweep handles all regulatory agencies and has all the relevant permits.
  • Pick-up minimizes your liability for any environmental or human contamination.
  • Pick ups are usually made twice per year, in March and October, and you can register continuously.

Who Can Participate?

Any agribusiness, including farmers, ranchers, private individuals, commercial applicators, golf courses, greenhouses or nurseries who apply or store pesticides in Colorado.

What Kinds of Pesticides Will ChemSweep Pick Up?

Any unwanted, unusable, or banned materials that are classified as a pesticide. Examples of waste pesticides that have been collected include: DDT, chlordane, carbaryl, alachlor, lead arsenate, lindane, dinoseb, calcium cyanide, chloropicrin, 2,4-D, etc. Containers with unknown contents may require obtaining a sample for analysis.

How Much Does it Cost?

ChemSweep charges $3 per pound and has a minimum charge of $200. Materials are weighed on certified digital scales. You are charged based on the weight of the waste before it is packaged for transport.

How Can I Get Started?

  1. Use the ChemSweep Brochure to find out more about the program, or distribute it to others who need help with pesticide disposal.
  2. Use the ChemSweep Registration Form to request a pick up.

Container services network For Pesticde Container Disposal

Container Services Network (CSN) works with the Ag Container Recycling Council to dispose of pesticide containers properly and safely. In the event that a State or Agriculture business does not have a means of recycling, CSN works with them to recycle their crop protections containers. CSN provides bags for the collection of containers under 5 gallons, or they will pick up all containers (55 gallons or smaller) by truck.


How to Participate

1. All pesticide containers must be triple rinsed with caps and
labels removed per ACRC specifications.

2. All containers smaller than 5 gallons must be in bags to be
recycled. Each bag can hold approximately 40 of the 2½
gallon containers (about 40 pounds). Containers 5 gallons and
larger will be loaded loose onto the truck.

3. CSN will coordinate with each State/Ag organization and
collection point to schedule pickups. Collection sites and
applicators will be notified 48 hours prior to their scheduled

4. The site coordinator and contractor's agent will be responsible
for inspecting and approving the condition of containers for
