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 and the sticky card insert keeps them there. 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 sticky card insert. Check your traps periodically. If you catch large numbers of male moths, you may need to replace your cards several times in peak season.
