The trap should be located in the country, rather than in town. Avoid hanging traps near night lights. The sticky material will hold the septum in place. Change the lure and sticky bottom of the trap every 2 weeks. Store the pheromone lures in a refrigerator.
Cold storage is essential to maintain the attractiveness of the lures.
The top of the trap need be replaced only if it becomes severely damaged during storms. The captured moths should be removed from the sticky surface of the traps daily. Black cutworm moths apparently don't like to visit their captured colleagues. In an upcoming issue of this Bulletin, we will offer some projected cutting dates for black cutworms. Those cornfields most at risk include late-planted and weedy fields infested with winter annual weeds.
