Don’t kill the good guys!
More than 95% of insects aren’t pests. Some pollinate our flowers and vegetables, while many others feed on pests in our gardens as shown above. By allowing them to do their job, we can reduce the need for pesticides and maintain our local water quality.
How to…
Prevent pests
-
Use disease and insect- resistant plants
-
Monitor your plants regularly to catch problems early
-
Encourage birds, lizards and frogs – they can be very helpful in controlling insects
-
Properly identify problem pests before treating and choose treatment according to the pest
Attract beneficials to your yard
-
Plan the garden so there are blooming plants throughout the seasons to provide nectar and pollen
-
Provide an accessible source of water, such as a bird bath, small water garden or a pond and some rocks so they can access the water safely
-
Provide shelter – leave some leaf litter or plant some ground covers
Introduce populations of natural enemies
-
If you don’t have enough beneficals in your yard, purchase them from a nursery or commercial insectary
-
Follow release directions from supplier for optimum results
Make smart product choices
-
When spraying is necessary, select a narrow spectrum product whenever possible.
-
Broad spectrum insecticides don’t discriminate between pests and beneficial insects – they kill both. This can include naturally-derived products such as pyrethrum and rotenone as well as chemical products
-
Avoid over-use of pesticides – they can increase the chance of pest resistance
-
Choose an insecticide that won’t harm other insect-eating garden creatures like birds, bats, spiders, lizards, and toads (see last page and Grow Green Products fact sheet for ratings)
-
Treat only the outbreak area
-
Choose products that break down quickly like soaps or pyrethrum sprays
Be patient
-
Tolerate a few pests – they provide a food source for beneficial insects
-
Resist the urge to spray when you first see plant damage – plants can withstand a lot of damage and you should allow time for beneficial populations to build up
-
Monitor outbreak areas – if beneficials do not populate, other solutions may be necessary

Your informed choices make a difference.
