Trap Spacing and Placement: When trapping for more than one species of moth, separate traps for different moth species by at least 20 meters (65 feet).
Method Notes:
The lure (a flex tube or laminate dispenser) should be stapled to the inside of the trap on the non-sticky area.
Trap should be used with ends open. Trap color is up to the State and does not affect trap efficacy.

Lure Placement:
Do not include lures for other target species in the trap when trapping for this target.
Lure Notes:
IMPORTANT: The three-component lure inhibits Lymantria dispar dispar (European gypsy moth); therefore, this lure should be used for surveys in areas with established European gypsy moth populations to reduce large catches of European gypsy moth.
In addition, the three-component lure has been shown to have higher nun moth captures in European populations. Therefore, the three-component lure may be more effective at detecting moths coming from European populations (i.e., in the Eastern United States and other areas along this pathway of introduction).
The one-component lure should only be used in areas without established European gypsy moth populations. The one-component and three-component lures are equally effective at detecting Asian populations; therefore, the one-component lure is acceptable for use in states that would expect the pathway of nun moth to be from Asia.
Lance (2006) states that L. monacha traps should not be assembled at the same time and space as L. dispar lures. They should also be transported separately to prevent cross contamination as L. monacha lure components are potent inhibitors of male L. dispar.
