Laurie from Danielson, Ct writes

Will Diatomaceous Earth 85% kill gypsy moth caterpillars?


No, Diatomaceous Earth 85% is not recommended to treat gypsy moth caterpillars. Using a BT insecticide such as Dipel Pro is a very common treatment for Gypsy Moth Caterpillars. Talstar P has also been effective on most stages of the caterpillar and can be used on ornamentals.
