SANDPOINT – State officials say the invasive Spongy Moth was recently detected in north Idaho for the first time in more than 30 years. The Idaho Department of Lands, in collaboration with the Idaho State Department of Agriculture and the USDA Forest Service, conducts extensive annual monitoring to identify new introductions. This includes placing thousands of traps throughout the state. These traps feature sticky inner walls and utilize a pheromone lure that mimics a female moth to attract males. The traps are deployed statewide during the moths’ flight period in summer and are collected in the fall for evaluation.
