In the US, 78 million households use pesticides in and around homes targeting pests ranging from bed bugs and mice to aphids and weeds. These pesticides can be extremely effective at reducing pests which cause health issues, economic losses, and compete with turf and ornamental plants. However, if used improperly, pesticides can be detrimental to human health and the environment, as well as increase homeowner costs. Understanding proper selection and application of pesticides will help homeowners use pesticides in a manner to keep themselves, their families and the environment safe while effectively managing pests in their homes and gardens.

The MSU Extension Pesticide Education Program (MSU PEP) can help determine the best way to manage your home and garden pest problems. MSU PEP can answer questions and direct you to appropriate resources and professionals regarding pest identification, selecting proper pesticides, reading the label, proper safety precautions, and diagnosing pesticide poisoning. MSU PEP can also assist homeowners in identifying pesticide injury from drift or the introduction of contaminated soil amendments.

Pesticide contamination often comes from soil amendments containing residual pesticides including compost, manure, and grass clippings. Home yards and gardens may also be contaminated from pesticide drift originating from applications outside your property causing non-target symptoms on desirable plants and trees.
