Trécé Wing Trap Kits contain everything you need for three months of monitoring. Trap has closed design with no spacers for capturing smaller pests, moths and insects such as Coddling Moth. Slots in liner for entry. Includes 1CP plastic trap top, wire hanger, three pre-stickied trapliners with counting grid, and three pheromeone lures. Replace liners as needed and lures every 3 to 4 weeks. Use two kits per block up to 10 acres in size, add an extra kit for every additional 10 acres. The Trécé pheromones lures are applied to rubber septas for even release over a 3 to 4 week duration for better capture rates. If you are not sure which pests are a problem in your area, check with your county Extension agent or land grant university.
