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. 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. Do not place product in areas where termiticides have been applied, at least 3' of the foundation wall.
