The City of Wyoming’s annual efforts to mitigate Gypsy Moth infestation in the city will continue this month, with aerial spraying of selected areas scheduled to start Monday, June 5.


Households in the affected areas should have received letters notifying of the city’s mitigation efforts.

“The City of Wyoming is once again taking measures to protect our neighborhoods against Gypsy Moths, and the aerial spray is targeted for June 5-7,” Megan Sall, Assistant City Manager, said in an email to WKTV Journal. “If weather cooperates, you may hear/see our contractor’s helicopter overhead as early as 6 a.m. on the 5th. Under ideal conditions, the entire application will take 4-5 hours to complete. The contractor will start in the southern portion of the City and work his way north.”


According to the city, the insecticide being used is derived from a naturally occurring bacteria and is known only to affect Gypsy Moth caterpillars. It does not affect honeybees or other non-leaf eating insects, birds, fish or mammals. The insecticide is applied at a quart per acre in a very fine mist that targets the trees. The carrier liquid is water and drying usually takes place within a few minutes.


Despite the fast-drying nature of the mist, the city spokesperson said, residents are encouraged to exercise common sense and stay inside while the spray is occurring in their neighborhoods.


A map of the affected areas and more information can be found on the city’s website, as well as available on the city’s Facebook page.
