Mosquito treatment begins Friday at Horan Natural Area, Confluence State Park

by Rachel Hansen | Jun 12, 2023

Mosquito treatment is scheduled to begin June 16 at Horan Natural Area and Confluence State Park. PUD crews plan to apply pellets to control mosquitoes in and around ponds starting around 8 a.m.

“We want to thank everyone for their patience,” said Parks Superintendent Kyle Endelman. “We have to wait to treat the area until the spring runoff recedes. Otherwise, high-water flows would sweep the pellets away and the treatment would be ineffective.”

Chelan PUD uses a larvicide known by the brand name VectoLex CG. The pellets are safe for use around people and pets.

In the meantime, Chelan PUD is encouraging park visitors to take precautions to prevent mosquito bites, or explore different areas to recreate until conditions improve.
