Pesticides Illegal in Garbage or Drains Hazardous Waste Never Pour Down the Drain Pesticides should never be poured down the drain because they contain toxic chemicals that will contaminate waterways. Instead, dispose of them as hazardous waste. Don't Water the Grass After Absolutely do not water the grass after applying garden chemicals. This runoff ends up in storm drains that feed directly into nearby lakes and rivers. It also reduces the effectiveness of your pesticides. Don't Use if It's Going to Rain Avoid using chemicals before a storm. If you do, they will wash down storm drains and into nearby waterways when it rains. Ready-to-Use Containers Empty containers that held ready-to-use chemicals can be thrown in the garbage 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 away to a friend or neighbor. 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.
