Committee authorizes mosquito adulticide contract despite pollinator concerns

St. Lawrence County Legislature — Maine Services Committee · May 11, 2026

Summary

The committee authorized a contract extension with Duflo Spray Chemical for adult mosquito control that the county would only use if surveillance shows a human‑health threat; one legislator raised concerns about impacts on bees and aquatic life.

St. Lawrence County authorized the chair to contract with Duflo Spray Chemical Inc. for mosquito adulticide application as a continuation of a prior bid. County public‑health staff said the county would only implement adulticiding if surveillance indicated a serious risk to human health, citing the 2024 spike in eastern equine encephalitis as background.

Legislator Parkins pressed environmental concerns: "Pyrothoids are part of this adulticide that's sprayed out ... that actually kills bees, butterflies, dragonflies, fireflies, aquatic organisms, and fish. So I I'm not sure if the benefit is worth that. You know, so I'm not gonna support this," Parkins said. The presenter responded the company described a dose that "would kill a mosquito but not a housefly," and the motion carried with a recorded 'No' vote noted in the transcript.
