2020 brought us COVID-19 and caterpillars. With the caterpillars, at least there are things we can do. Put out these 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. These kits come complete with lures and sticky insert cards which can be changed yearly. The traps themselves should last several seasons.
