Please refer to Frequently Asked Questions About Using Insecticides for information on how to apply materials and relative effectiveness of products.

Print Table 1: Pesticides Used to Control EAB by Application Method

Table 1. Insecticide options for professionals and homeowners for controlling EAB that have been tested in multiple university trials. Some products may not be labeled for use in all states. Some of the listed products failed to protect ash trees when they were applied at labeled rates. Inclusion of a product in this table does not imply that it is endorsed by the authors or has been consistently effective for EAB control. See text for details regarding effectiveness.
