{ } Moth Box contains: The moth pheromone vaporises into the immediate environment & attracts male moths which cling to the sticky surface. Once trapped on the adhesive board, the female moths are not fertilised, so the amount of moths is slowly reduced. The number of moths caught give an indication of the extent of the infestation, so the moth box can also be used to check how many moths are present. Active life: 12 weeks after opening protective packaging. View all the eco products in our section, or click on any of the links on the left hand side to see more.
