Mark the traps permanently with the lure type used, and always use the same lure type with that trap. Also, do not use more than one lure in a trap at the same time . Carry empty lure packages away from the monitoring site and dispose of them properly. You can refrigerate or freeze lures for longer storage lives. Lures stored for more than one season may not retain peak effectiveness.
Discard lure away from trapping area.
Change lures and liners as recommended. Don't use more than one type of lure per trap. Don't handle different lures without washing your hands in between. Don't puncture or cut the lure in any way. The scent will permeate the lure material more quickly .
