Spotted lantern flies are a highly invasive species rapidly spreading across North East America. These pests lay eggs on trees, hatch in the spring and by summer the nymphs turn to adults and are flying from tree to tree and hitchhiking on cars and trucks. This wintergreen scented trap is 20 ft long and traps nymph and adult lantern flies. Carefully unroll the trap paper and wrap around tree trunks. Once the section is full, cut off the used section and unroll the new section.Traps and holds all life cyclesUse outdoorsLasts for months
