I need to treat for extreme case of mosquitoes in Northern MN and do not want to kill the dragonflies that eat our mosquitoes. Natural defense but this year there are way too many mosquitoes and the dragonflies just started to hatch
Unfortunately there isn't a way to only kill one species and not the other and broadcast treat an area they may both cohabitate in. However, most insects have times of day they are most active and least active, so spraying during the least active times for dragonflies can give more time for the product to dry and potentially not impact them as much the following days. There is just no way to guarantee they wont be impacted to some extent when using an insecticide whether all natural, orgranic, or otherwise if it carries a residual.
