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:
Contact your CAPS Regional Program Manager to discuss if it is appropriate to trap for Asian gypsy moth in your state.
Paper delta trap:
Delta traps are used outside of areas that are generally infested with European gypsy moth, where catch is expected to be less than 10 moths per trap. The lure should be stapled inside the trap, to one of the non-sticky panels. The ends of the trap should be folded in. Trap color is up to the State and does not affect trap efficacy.
Milk carton trap:
The standard milk carton trap has a much higher capacity and should be used in areas where populations of European gypsy moth are established. The lure is typically stapled to a long garden tie that is, in turn, stapled to the inside of the trap at the top so that the lure hangs more or less in the center of the trap. A killing agent, a DDVP strip, is required for milk cartons traps. The DDVP strip should be stapled to the garden tie below the lure.
Trap Placement:
Traps should be hung in the immediate vicinity of preferred host trees. Milk carton traps should be hung using a string, tied to a branch of a host tree. Delta traps are most effective when attached directly to the bole of a host tree. If no host tree is available, another vertical surface such as a telephone pole can be used to hang the trap. Never hang the traps on branch tips.

Lure Notes:
The length of effectiveness for the Gypsy Moth String Lure has been revised from 84 days (12 weeks) to 180 days (6 months). The Gypsy Moth Laminate Lure is still effective for 84 days (12 weeks). If it is appropriate for your climate/ planned survey season, please use the Gypsy Moth String Lures for the full 180 days. If you ordered the string lures based on the 84 day length of effectiveness and have excess lures, please store the excess lures in unopened packages in a freezer for the next season. The lures may be stored for two years if stored in a freezer below 0F. In future years, if using the Gypsy Moth String Lure, please plan your surveys based on the revised length of effectiveness.
