It is very important that beetles are contained within Washington County while treatment takes effect. Containment efforts are ramping up, with a quarantine on all yard debris still in effect and expanding in 2018. Residences will receive electronic notices from Oregon Department of Agriculture, along with other communications planned throughout the summer.

For more information about the quarantine check back on our Prevention page for the most recent information.

Summary of the 2018 Treatment
The ODA continued their relationship with General Tree Service to apply the same treatment as last year, a granular pesticide called Acelepryn G® which is a targeted larvicide that kills certain pests in their larval state in the soil. The granules are broadcasted on lawns and other landscaped areas, then it breaks down into the soil when it is watered in through rain or sprinklers. This pesticide is a “reduced risk” pesticide and is not considered a health threat for humans, pets, and other insects that don’t go through a larvae stage in treatment areas. According to the label, “Acelepryn G is recommended for Integrated Pest Management programs on turf and landscape ornamentals because it does not directly impact natural arthropod predator and parasitoid populations including ladybird beetles (aka ‘ladybugs’).”  Since the treatment targets certain pest larvae in the soil, the treatment with Acelepryn G® has no adverse effects on pollinators when applied according to the label instructions.

A snapshot of the treatment area in Washington County

While there have been some delays due to weather, treatment has been able to be completed as scheduled due in large part to the hard work by application crews. A big shout out to the crews members and crew leads who are working long days, rain or shine, to make sure treatment is done correctly and on time.
