Horticultural Soaps

Horticultural soaps are environmentally friendly pesticides that can be used on small, soft-bodied pests like aphids, mealybugs, whiteflies, and spider mites. They can be used on indoor and outdoor plants, including vegetables. You can find homemade recipes on the Internet, but the results from commercially available sprays are more predictable. Timing is important, so follow the label instructions. For example, spraying on a hot day may cause damage to the plant. Horticultural soaps only work when they come in direct contact with pests; you may need to reapply weekly.
