Many of us have seen how much damage this pest can do, especially in young fruit trees. Severe infestations can even defoliate larger shade trees. Put out the traps the first week of July to disrupt the gypsy moth cycle. The newly emerged male moths are attracted to the female pheromone scented lures. Eliminating males at the start of mating season directly impacts the number of eggs being fertilized for next year's crop of caterpillars.

Each trap needs 1 pheromone lure. The lures should last between 3-6 months which is long enough to cover the adult moth period. The traps may be taken down in September for use again the following year with new lures and sticky cards.
