Japanese Beetle Treatments: What Residents Need To Know
Watch this video below to learn more about Japanese beetle treatments including how to sign up, prepare, and know when your treatment is complete.
Planned treatment areas
Are you located in a Japanese beetle treatment area? View the 2024 treatment maps below or enter your address in the interactive map to see if you are in a planned treatment area.
Please note that if any portion of a property falls within the treatment zone, the entire property will be treated. Acelepryn® will not be applied to land within the 200 ft shoreline buffer area.

Treatment FAQs
See the Frequently Asked Questions below about treatment.
WHAT INSECTICIDE WILL WSDA USE TO TREAT MY PROPERTY? IS IT HARMFUL?
WSDA uses the insecticide Acelepryn®. It kills certain pests in their grub (larval) state in the soil. It is a "reduced risk" pesticide according to the Washington State Department of Health. It is not considered a health risk for humans, pets, wildlife, or other insects that don't go through a larval state in soil (including pollinators like bees). For more information visit Washington State Department of Health's website on Japanese beetle treatment.
I PREVIOUSLY PROVIDED CONSENT. DO I NEED TO GIVE PERMISSION AGAIN?
Yes, you must provide consent each year. Thank you for your support!
DO I NEED TO BE HOME DURING THE TREATMENT?
- You are welcome to but do not need to be home.
- The treatment may take place between 8 a.m. and 5 p.m. in April, May, or June.
- You will be notified before the treatment via the contact information you provide on your consent form.
WHAT SHOULD I DO BEFORE THE TREATMENT?
- Please make sure your lawn is clear
- Please unlock your gates
- If possible, have your lawn mowed.
- Residents and animals should be kept away from the treatment area until dry
How do I know the treatment is over?
If you are home, representatives can answer any questions. Once the area is dry it is safe to re-enter.
- A sign will be left notifying you that your treatment is complete.
- If possible, please refrain from mowing your lawn immediately after treatment.
What if I am a renter?
Renters have the authority to consent to treatment for property in which they physically dwell. You are, of course, welcome to discuss the project with your landlord.
I AGREED TO TREATMENT, BUT THEN I SAW BEETLES IN MY YARD THE FOLLOWING SUMMER. IS IT WORKING?
Although the applications are done in the spring, you won’t see the full effect until the following year, so you will likely still see beetles in the area, and it will likely take several treatments before the beetle can be totally eradicated. We need all properties to agree to treatment to succeed. If we are unable to treat a neighboring property, beetles from that property are likely to show up in your yard, too. This is why it is important to encourage your neighbors, friends, and family in treatment areas to agree to have their property treated.
WHAT IF I DECLINE TREATMENT OR DO NOT RESPOND?
Untreated properties become a haven for beetles, prolonging their ability to remain in the state. Because of this, WSDA may seek administrative warrants through the courts to treat properties that decline or do not respond to treatment requests.
WHAT HAPPENS IF WE DON’T ERADICATE THE BEETLE?
We don’t have to guess about the impacts this beetle will have on our state; we need only look at states that have permanent infestations of the beetle. Farmers and plant nurseries are subject to expensive and restrictive quarantines to move their products, as well as increased pesticide costs to manage the beetle. Residents must deal with the pest in their lawns and gardens as well, either increasing pesticide use or manually removing the beetles – some even using vacuums because of the sheer number of beetles. Visitors and tourists must also deal with the beetles being a nuisance flying into them while trying to enjoy the outdoors. We can avoid all this by eradicating the beetles now.
I HAVEN'T SEEN JAPANESE BEETLE. WHY SHOULD I SIGN UP FOR TREATMENT?
Japanese beetle grubs live in soil. Adults lay eggs in lawns and soil where you can’t see them. We deploy thousands of traps in the area to catch Japanese beetle adults and to help prevent them from laying as many eggs. Our trapping can help keep adults off your plants and trees where you might see them. Applications are the only way to treat the grubs, that is why it is important to sign up for treatments to target the pest before you see it.
PUBLIC HEALTH
Acelepryn® G and Acelepryn® have an excellent safety record when used as directed. You can limit contact with the product by following the safety recommendations:

- Avoid the area and keep pets inside until the treatment has dried.
- If you come in contact with the pesticide, wash the affected skin with soap and water.
- Remove and wash exposed clothing. Keep and wash clothing separate from other laundry.
- Experts do not expect health concerns from eating produce grown in Acelepryn® G or Acelepryn®-treated soil.

Public Treatment
You can protect gardens by placing a trap nearby to capture any beetles that may from the soil. If you capture beetles, please report them.
Do not treat for Japanese beetle if you do not have the pest.
If you have beetles, you may be interested in extra self treatment. Please contact your local Washington State University Extension for information. Click the link below to open a self treatment handout
2025 Treatments
2025 treatment sign-ups are closed.
Treatments apply a “reduced risk” pesticide that is not considered a health risk for humans, pets, wildlife and other insects (including bees) that don't go through a larval stage in soil. You must sign up for treatments each year for every property that you own or rent. Multiple treatments are required to remove Japanese beetle.
