Always consult the label before making pesticide applications. Labels vary greatly among commercial products of the same material. It is important to refer to the label for the best timing and application rates when applying pesticides. Also read the text for information on cultural practices to minimize the application of pesticides.

Caution: Broad-spectrum insecticides (those with a large number of pests listed on the label) have significant potential to be harmful to non-target organisms such as bees and other beneficial or predatory insects.
