Q: How should pesticides (for home use) be stored? What is the shelf life?


A: Pesticides should be stored in a secure, well-ventilated area, preferably locked in a safe cupboard, garage or garden shed. Most pest control products can be stored for extended periods at temperatures above freezing. Check all labels carefully for specific information.

Other safety rules to follow:


Store products ONLY in the original container. NEVER transfer the contents to another container.

Keep containers tightly sealed.

Pay attention to the symbols illustrating the risk of flammability, explosiveness or toxicity before storing or using.

Do not use kitchen or food measuring utensils to measure any pest control chemicals.

Containers with the "flammable" symbol should be stored away from any sources of heat. Glass and plastic containers should be kept out of sunlight.

Don't store a mixed spray for use at a later date. Diluted materials quickly break down to become less effective.

Most pest control products can be stored for extended periods at temperatures above freezing. Check the label for each product as certain products should be kept from freezing.
