What are Pesticides & Pests?


“Pesticide” is the general term for any substance designed to eliminate undesired insects, weeds, rodents, fungi, bacteria and other organisms. Pesticides come in many forms and even include house- hold bleach and swimming pool chemicals. Pesticides can be categorized as:
  • Insecticides (for insects)
  • Herbicides (for weeds)
  • Fungicides (for fungus diseases)
Although an individual lawn or garden may seem quite small, the combined effect of many lawns and gardens can have a significant impact on your neighbourhood and beyond. Making responsible choices to ensure the health of your small “piece-of-the-pie” will not only benefit you and your family but also the greater community.


Most bugs in your yard aren't all bad – far from it. They pollinate plants, decompose waste material and prey on many of those pesky insects that you don't like. Common yard and garden pests include ants, aphids, moths, cutworms, earwigs, slugs and tent caterpillars. Many insects, parasites and small animals are not pests, but were actually doing all the work in your yard long before you got there. These beneficial creatures include spiders, honeybees, ladybugs, frogs, snakes, bats, mice and moles. Resist any initial “get-rid-of-it” response when you see things in your yard.
