FARGO, ND (Valley News Live) –
There is anger and frustration with vector control when people found several dead monarch butterflies around the subway of Wednesday night’s spray.
One woman said she saw at least 100 dead butterflies while walking her dog Thursday morning.
Vectrol control told Valley News Live that Cass County covers 1,700 square miles and they sprayed only 100 square miles on Wednesday.
Officials said they are trying to keep the West Nile virus out of the subway as more cases appear in surrounding cities.
“You know I mean it’s absolutely sad and what we do not try to do, but without a doubt we spew a wide range of insecticides and it does not distinguish between beneficial insects or houseflies or mosquitoes,” said Ben Prather, director of Cass County Vector Control.
Vector control said another mosquito spray may be planned in the future, depending on data.
