PRESTRIKE MOSQUITO TORPEDO 5PACK

Pre-Strike Mosquito Torpedo effectively kills developing mosquitoes in standing water before they become breeding, biting adults.
How it works:
When dropped into standing water, Pre Strike Mosquito Torpedo sinks to the bottom where it slowly and continuously releases an Insect Growth Regulator (IGR) into the water to prevent mosquitoes from developing for up to 2 months. Mosquito larvae exposed to treated water will die in the pupal stage before they reach adulthood.
Can be used in water troughs, old tires, bird baths and many more standing water sites. Leaves water crystal clear, doesn't leave any unsightly debris. Won't harm humans, animals, fish or vegetation. Each torpedo contains 8.62% s-methoprene.
