Safe and Responsible Pesticide Disposal: What to Do with Unused Products

Proper disposal of pesticide products is essential for protecting human health, wildlife, and the environment. Improper disposal—such as pouring pesticides down the drain, into storm sewers, or onto the ground—can contaminate water supplies, harm beneficial organisms, and violate environmental laws. If you have old or unused pesticides, never throw them in the trash unless the label specifically allows it.

So what do I do with them? How and where can I dispose of them? What do I do?

General Disposal Guidelines:

Follow these general disposal guidelines to dispose of pesticides the right way:

1. Read the Label First

Always start by checking the product label. It will include specific instructions for storage and disposal. Follow them closely.

2. Never Reuse Empty Containers

Empty pesticide containers should never be reused — even for non-chemical storage. Residue can linger and cause harm.

3. Package and Store Safely

If you're not disposing of them immediately, keep pesticides in their original containers with labels intact. Store them in a secure, upright position away from food, children, and pets.

4. Don’t Dump or Trash Them

Never pour pesticides down the drain, onto the ground, or into the trash. These actions are unsafe and in many places, illegal.

5. Use Authorized Collection Services

Dispose of pesticides through certified programs like Household Hazardous Waste (HHW) Collection Days or licensed hazardous waste vendors.    Find Household Hazardous Waste collection events here (PDF)
