Why spray for seven moths?
This is not a suppression treatment to reduce a nuisance species like mosquitoes. Catching gypsy moths two years in a row in the same neighborhood is firm evidence that a breeding population is established there. Gypsy moth is an exotic pest of national concern. Eradicating this infestation will prevent the population from becoming permanently established and spreading throughout the state. Eliminating invasive species early prevents ecological and economic damage; this results in less use of pesticides in the future. Keeping invasive species out of Oregon is good for the environment.
