Hi Dan –

Instructions for Using Gypsy Moth Trap

Pheromone Monitoring
Pheromone lures and traps provide an effective means of monitoring Gypsy Moth. Each lure contains a synthetic sex pheromone that mimics the odor that the female moth uses to attract males for the purpose of mating. male moths are attracted into the trap and cannot get out. Trap counts, when taken on a regular basis, can give an accurate picture of population emergence and distribution.

Numbers of Traps and Lures Needed
For survey and detection of populations, only one trap/lure is needed for every three square miles. A larger number of traps, approximately thirty two per square mile, would be needed to determine the distribution within an infested area. the traps should be placed in a grid pattern.

Life expectancy of the Gypsy Moth lure in approximately four weeks. You will need to purchase enough lures per trap to complete the monitoring season.

Timing for Placement of Traps
Monitoring should begin in early summer, just prior to the moth flight.

Placement of Traps
Traps should be placed at eye level in the canopies of the trees being monitored. When using more than one Gypsy Moth trap, never place them closer than thirty feet apart.

Trap Counts
Traps should be be checked and insects cleaned out and counted regularly, prefer- ably at least twice per week. Consult your local county extension agent or university Entomology department to learn more about Gypsy Moth in your area.

Hope it helps!
