Alternatives to Pesticides
Why Use Alternatives?
Pesticides are among the most widely-used chemicals in the world, but are also among the most hazardous to human health, sometimes causing serious acute and chronic health effects.
When used by trained professionals as part of an Integrated Pest Management Plan, pesticides can still be a valuable tool in managing noxious weeds or other invasive organisms to protect infrastructure, ecosystems and human health.
Pesticides include insecticides, herbicides, and fungicides. Although these products are designed to kill insects, weeds, and fungi, there is no guarantee that they can fully get rid of these pests. In fact, by using pesticides, insects that are beneficial to the garden ecosystem may also be destroyed.

Alternatives to cosmetic pesticides are generally more appropriate and less harmful to humans and the environment in the long run. Such alternatives often involve implementing better gardening strategies that solve pest problems in a natural, long-lasting way. Alternatives are also less harmful to the applicator and other people in the area. Making a difference in the environment can begin in our own backyards!
