Eradication Update: 2019

The primary treatment operations to eradicate Japanese beetle for 2019 have been completed! This year we treated 8,200 properties in Washington Co. between April 2 and June 7. Thank you to everyone for your continued support!

This year, for the first time, we decided to do a supplementary foliar application in areas with higher beetle density. We are supplementing the granular treatment (Acelepryn G®) with a foliar spray (Acelepryn®) that in areas within 200 meters of a trap that collected 75 beetles or more.  The foliar spray has the same active ingredient (chlorantraniliprole) as the granular treatment, and therefore the same minimal risks. While Acelepryn G® was applied to turf and ornamental plants in an effort to target Japanese beetle larvae, the Acelepryn® foliar spray will be applied to ornamental trees, shrubs and plants in an effort to target Japanese beetle adults. This application is both free and voluntary, and you will be notified if your home falls within this smaller treatment area of approximately 800 properties.
