Spongy Moths – What is the Plan for 2024?
At its January 8th board meeting the Township received a report from Aquatic Consulting Services on the Egg Mass Survey they completed on behalf of the Township this winter. This survey was intended to determine the success of the spongy moth spray services that were completed in the spring of 2023.
The report indicated the spraying services were highly successful with Aquatic Consulting Services only recommending 289 acres (shown on the map above) for spraying compared to 2,967 acres in 2022 and 654 acres in 2023. According to Aquatic Consulting Services the entire reduction is not due to spraying, but also other environmental factors that play a role in the life cycle of spongy moths.
The Township Board discussed how to proceed at its January 8th and January 22nd board meetings and determined that these spray services benefit the entirety of the Township, and the cost would be paid out of the general fund as opposed to a special assessment to impacted property owners. Following the discussion, the board approved a proposal from Hamilton Helicopter to spray the 289 acres for a cost of $23,018.85. The next step is to provide a letter to all impacted property owners so they are aware of what will happen and when – if your property is located in the impacted area shown on the map you will receive a letter from the Township with additional information.
If you have any questions about Spongy Moths or the potential spray program please contact Julius Suchy, Township Manager at 616-676-9191 ext. 7348 or via e-mail at jsuchy@adatownshipmi.com.

2023 Spongy Moth Plan
At its January 9th board meeting the Township received a report from Aquatic Consulting Services on the Egg Mass Survey they completed on behalf of the Township this winter.

The report indicated the spraying services were highly successful with Aquatic Consulting Services only recommending 654 acres (shown on the map above) for spraying compared to 2,967 acres last year. According to Aquatic Consulting Services the entire reduction is not due to spraying, but also other environmental factors that play a role in the life cycle of spongy moths.
The Township Board discussed how to proceed at its January 9th and January 23rd board meetings and determined that these spray services benefit the entirety of the Township so the cost would be paid out of the general fund as opposed to a special assessment to impacted property owners. The next step is to provide a letter to all impacted property owners so they are aware of what will happen and when.

2022 Spongy Moth Spray Services - why are we spraying?
At the January 10th Township Board Meeting, Neal Swanson of Aquatic Consulting Services provided a report on spongy (gypsy) moths following physical surveys completed by Aquatic Consulting Services this winter. The full report including maps is available by clicking on the links at the bottom of this page.
In summary the report confirmed that the areas of concern referenced by residents and Township officials are infested with spongy (gypsy) moths. Mr. Swanson believes that Ada was able to catch the populations on the rise and using the survey data, will be able to create a spray and monitor protocol that will limit further population growth and damage throughout the Township.
The total acreage recommended for spraying is 2,967 acres. The spray area as outlined in the report is only the areas with significant, potentially damaging population densities. There are areas with less severe infestations that were not recommended for spraying, but should be monitored moving forward.
The Township board voted to move forward with a spray program in 2022 and has entered into an agreement with Hamilton Helicopter to spray in late May or early June of 2022 - weather dependent. The Township has mailed out letters to all property owners whose property is located in the areas to be sprayed.
Based on the quote from Hamilton Helicopter, it is estimated the cost for the upcoming year will be approximately $200,000. The Township Board has included funding for this program in the adopted FY 2022-2023 budget. Future years of the spray program will be covered by a special assessment to impacted residents, although this will be discussed next year prior to a special assessment being finalized. Any resident who would be subject to the special assessment would be notified well in advance of this action taking place.
Any questions regarding the report or process summarized above can be sent to Julius Suchy, Township Manager via e-mail jsuchy@adatownshipmi.com, or via phone 616-676-9191 ext. 48. I understand that residents will have a number of questions and I recommend you read the full report with maps on our website before reaching out with questions.
