FARGO Late last summer, a mass die-off of monarch butterflies occurred in the Fargo-Moorhead area after aerial spraying was conducted to control mosquitos.
Images of the aftermath, including photos of dead monarchs, captured the attention of social media as well as national and international mainstream media.
Ultimately, state agencies tasked with regulating pesticide applications determined the aerial sprayer hired by Cass County Vector Control, which conducts aerial spraying to control mosquitoes over the Fargo-Moorhead metro area, committed no violations when it sprayed for mosquitoes the evening of Aug. 26.
Letter: A healthier approach to mosquito control
If all was done correctly on Aug. 26, which is what Cass County Vector Control director Ben Prather and the investigators say, there is only one conclusion: Something is missing from our knowledge about the safe use of permethrin.

An insecticide intended to kill the target (mosquitoes) mysteriously kills thousands of non-targets (monarch butterflies). A mosquito weighs about 5 mg; a monarch butterfly weighs about 500 mg.
To get a handle on this size difference, you might compare this to a weed killer that mysteriously destroys 16-foot trees in addition to the intended target: 2-inch weeds.
Bees and butterflies are active for up to two hours after sunset. In order to protect pollinators from aerial or truck mounted pesticide spray, many cities have gone to dusk and night spraying.
