What do I do with household chemicals?
Household hazardous waste (HHW) is anything with a "caution," "warning," "danger," or "poison" label — pesticides, cleaners, pool chemicals, fertilizers, old thermometers, CFL bulbs. None of it belongs in the trash or drain, but Missoula runs periodic HHW collection events that take the lot for free.
Step 1 — Best
Reduce
Don’t create the waste in the first place.
- •Buy the smallest bottle that does the job — "value-size" pool chemicals sit in garages for 20 years.
- •Switch to vinegar, baking soda, and castile soap for everyday cleaning.
Step 2 — Better
Reuse
Give it another life — donate, sell, or repurpose.
- •Unopened, labeled products: post on Buy Nothing — a neighbor might have exactly the project you're done with.
- •Home ReSource will accept some HHW categories (paint, certain solvents) during regular hours — call first.
Step 3 — Good
Recycle
Proper drop-off keeps materials in the economy.
- •Missoula County Household Hazardous Waste collection events: free for Missoula County residents, held a few times a year. Check ZERO by FIFTY or the county's site for the next date.
- •CFL light bulbs: Home Depot and Lowe's have free drop-offs.
- •Mercury thermometers and switches: HHW events only.
Last Resort
Heads up
Never pour chemicals down drains, on the ground, or in the trash. Store them in their original containers in a cool dry place until the next HHW event.
