5 Steps to Protect Your Family’s Health & the Environment Too

1. Avoid Household Products Marked “Danger

“Danger” means the product could poison you, cause serious damage to your skin or eyes, or easily cause a fire.

Choose instead:

  • Products marked “caution” or “warning” or products that don’t need warnings.
  • Products that are water-based such as latex paint, white glue, and some paint strippers.

2. Reduce Your Need for Yard & Garden Pesticides

Pesticides are poisonous. Besides killing bugs and weeds, they may also poison children, irritate eyes or skin, cause cancer, or kill birds and fish.

Take action by:

  • Building healthy soil by adding compost or aged manure and using slow-release organic fertilizers
  • Buying plants suitable for your site
  • Trying non-chemical products to control pests, such as:
    • Teflon tape for root weevils or soap and water solution for aphids

Call the Whatcom County Extension Office for more tips at 360-676-6736.

3. Recycle Used Motor Oil

Oil dumped in storm drains is not treated and ends up in our streams and lakes, affecting fish and birds. For curbside collection, place your motor oil in a well-marked, tightly sealed plastic jug (do not use bleach bottles) and set out next to recyclables. Disposal of Toxics has oil and antifreeze collection stations set up throughout Whatcom County.

These locations are listed above.

4. Use Less Toxic Cleaners

Some cleaners contain hazardous ingredients that can burn your eyes, skin, or lungs. Look for safer name brand substitutes or use these simple alternatives:

  • Ovens: Prevent the need! Line the bottom of the oven with aluminum foil and clean spills right away. To clean, try a cleaner without lye or a non-chlorine scouring powder, or try soap, water, and a copper scrubber.
  • Drains: Use a plunger, snake, or hose-end bladder. Prevent clogs by pouring boiling water down a slow drain, or try a product that uses enzymes to break down grease and soap.
  • Toilet bowls: Use baking soda and castile soap, non-chlorine scouring powder, or other less-toxic commercial products.

5. Dispose of Leftover Hazardous Products Properly

Never pour hazardous waste down the sink or storm drain; the chemicals can end up in local waterways or groundwater. If you throw them in the trash, the chemicals can endanger collection and disposal workers. For proper disposal options, please refer to the information provided below.
