Biorational Insecticides

Gardeners who want to find safe and non-toxic ways to manage pests in their garden should try biorational insecticides.

Biorational insecticides are typically used to target soft-bodied pests like caterpillars or aphids. They provide a relatively non-toxic alternative to conventional insecticides, often with few ecological side effects. They include horticultural oil and insecticidal soap sprays, plant-derived insecticides like neem oil and pyrethrum, and microbial pesticides like Bt.

Timing is important, and you may need to repeat applications to get the best results. Check the product label for more information. By choosing to use biorational insecticides instead of conventional insecticides, you'll be able to manage pests with minimal effect on beneficial insects.
