Illegal in Garbage, Recycling & Drains
Hazardous Waste

Pesticides can be disposed of through the County Household Hazardous Waste Program.  

To avoid the potential pollution associated with pesticide use and creating this hazardous waste in the first place, consider Integrated Pest Management strategies instead which will help protect your health as well as local insects and birds.

Never Pour Down the Drain

Pesticides should never be poured down the drain because they contain toxic chemicals that can contaminate waterways. Instead, dispose of them as Household Hazardous Waste.


Don't Water the Grass After

Absolutely do not water the grass after applying garden chemicals. This runoff ends up in water drains that can contaminate lakes and rivers. It also makes your pesticides less effective against pests.


Don't Use if It's Going to Rain

Avoid using chemicals before a storm; if you do, they will be washed down storm drains, or leach into the soil, once it starts raining.

Rinse Empty Concentrate Containers

Containers that held concentrate need to be rinsed out three times before they are thrown in the trash: to do this, add remaining spray to the tank. Next, add water into the container, swirl and then transfer to the spray tank. Finally, repeat these steps twice.


Ready-to-Use Containers

Empty containers that held ready-to-use chemicals can be thrown in the trash without rinsing them out.

Ways to Reduce

Use Up Completely

The best way to dispose of pesticides is to use them up completely, which reduces how much can leach into the environment. If you’re not going to use them up completely, try giving them to a friend.


Avoid Purchasing Concentrate

Consider purchasing ready-to-use products. Purchasing concentrations to dilute on your own can expose the body to harmful chemicals. Also the use of  under-diluted chemicals is more damaging to the air, water and soil.

Use Bait Stations or Insecticidal Soaps

Identify your pest problem and use the least toxic option to eliminate those pests (if you must use garden chemicals). Consider using bait stations or insecticidal soaps and oils. Find out more.
