Why storage conditions matter
Pesticide products are formulated for a specific range of temperature, humidity, and light conditions. Storage outside these conditions can: — Degrade active ingredients, reducing efficacy (you paid for a product that no longer works properly) — Separate formulation components (emulsifiable concentrates can phase-separate at temperature extremes) — Compromise container integrity (freeze-thaw cycling can crack plastic bottles and compromise seal integrity) — Increase vapour pressure (overheating a sealed container increases internal pressure and can lead to leaks) For BC homeowners with consumer pest products, the practical storage rule: a cool, dry interior space (not the garage in summer or winter, not the bathroom, not under a sink where a leak could compromise the container) is the correct location. A locked interior cabinet is ideal.
Legal storage requirements in BC
Under the BC Integrated Pest Management Act and the federal Pest Control Products Act, pesticide storage requirements are specified on the PMRA product label. The label is a legal document — storage in conditions that violate the label is a regulatory violation. Typical label storage requirements: 'Store in a cool, dry place. Keep out of reach of children and pets. Store away from food, beverages, and animal feed. Do not store near open flames or heat sources.' For professional applicators (like Wild Pest), additional requirements apply: secure storage in a locked facility, inventory records, and prohibition on storing products in residential spaces. Wild Pest does not leave product at client homes — all product stays in our licensed storage.
Child-safe storage at home
- Store all pest products in a locked cabinet — the same type of locking storage used for medications.
- Keep original containers with labels intact — never transfer product to unlabelled containers.
- Store above child reach height, even in a locked cabinet — belt-and-suspenders approach.
- Do not store pest products near food or food preparation areas.
- Inspect containers regularly for leaks or compromise — dispose of damaged containers at HHW depot immediately.
- Keep BC Poison Control (1-800-567-8911) posted on your refrigerator or saved in your phone.
Disposing of leftover pesticide in BC
Never pour pesticide products down the drain, into storm drains, or into regular household garbage. These routes cause water system contamination and violate BC Environmental Management Act requirements. The correct disposal route for homeowners: BC's Hazardous Household Waste (HHW) depots, operated through Metro Vancouver, the Capital Regional District, and regional districts across BC. These accept unused pesticides, paints, solvents, and other hazardous household products at no charge. The Product Care Association operates PaintCare and CleanFARMS programs that accept agricultural and commercial pesticide products. For Metro Vancouver, the HHW depot at 377 SE Marine Drive (Vancouver) and the North Shore Transfer Station operate on a drop-in basis. Regional district websites list all local HHW drop-off dates and locations.
