For use in Trelona Advance Termite Bait System. Trelona is a compressed termite bait that has an active ingredient, novaluron, which is an insect growth inhibitor. When Trelona is eaten by the termite, novaluron harms the ability to properly synthesize and inhibits the termite to molt. When this is consumed by a termite, it will impair the ability of a termite to properly synthesize chitin and disallow the termite to molt. By being unable to molt, they are not able to form a replacement exoskeleton. Termites will either die or are incapacitated by their inability to complete the molting process. Consumption of the bait will cause the termite colony to decline, and by continued consumption, the remaining termites may result in the total elimination of the colony. Box comes with 6 bait cartridges. Net weight: 6 x 4.37 ounces (6 x 124 grams)
