Invasive moth found in Sandpoint, first time in 30 years

SANDPOINT, Idaho — Idaho Department of Lands is working to stop the spread of an invasive moth species detected in Sandpoint.

According to IDL, the department conducts annual testing which involves placing thousands of traps in statewide.

IDL says one trap captured a moth suspected of being an invasive moth and further testing confirmed it was a European spongy moth. The moth was found in a trap placed near Division Street and Oak Street.

IDL says the moth was likely introduced accidentally by someone traveling from the East Coast back to Idaho. IDL says the moths and their eggs can hitchhike via firewood, campers, outdoor furniture, or vehicles.

The moth feeds on leaves, in particular oak trees. This could cause millions of dollars in damage if an outbreak occurs, according to IDL.

IDL says residents may see more traps placed beginning in the summer of 2025 as the department works to keep the species under control.
