Even though several cities have enforced or are considering pesticides bans (Calgary, Alberta is one of the recent examples), inevitably there will still be people determined to spray their lawns and gardens. If you're one of them, think of pesticides like you do your car: yes, they can be harmful if used improperly, but if handled properly with care, you can greatly minimize the associated risks.
Before spraying
☆ Do consult the label and ensure you're using the correct product such as an herbicide or insecticide, for the pest you need to control. Also be sure to wear any protective clothing recommended on the label or product fact sheet. This could include long pants and long-sleeve shirts, gloves, goggles, a hat or boots. Keep the label and make sure it is always in readable condition.
☆ Do only use the pesticide for the job it is intended to do and only use the recommended amount (using more does not make it more effective).
☆ Don't transfer the pesticide out of its original container if not absolutely necessary. If a new container is required, ensure it is properly labeled with the name of the pesticide, as well as the label and safety instructions. Never use a container that is used for food or drinks.
☆ Do not burn pesticides, pour them down a drain (household, sewage or otherwise).
Mixing
☆ Do mix in an area with good ventilation and proper lighting.
☆ Do read the label carefully and mix according to the instructions. Estimating the correct amounts or ratios is not okay.
☆ Don't rip the bag open or open using a knife or scissors that are used with food.
Spraying
☆ Do keep the container below eye level to prevent splashing or spilling the liquid on your face.
☆ Do put in signs in the area where you are spraying to warn others to stay away, and when re-entry is safe.
☆ Do spray at a time when the least amount of people will be around or affected as possible, such as a weekend or end of the day.
☆ Don't use equipment that is leaking or loose.
☆ Don't mix or spray on a windy day.
☆ Don't spray anywhere near other people (especially children), animals, toys, food or food-related items (ie. dishes, picnic tables, etc).
Storage
☆ Do store according to instructions and put in an area that cannot be easily accessed by children. the area should be locked, dry, well ventilated and temperature-controlled.
☆ Do keep the pesticides in the original container and ensure the labels remain readable.
☆ Do ensure they are kept upright and the containers have no leaks, tears or any other malfunction that could be dangerous such as a loose lid.
☆ Do not store near food, food-related items (dishes or utensils), animal feed, seeds or water.
