Pot poppers are a biological control that works by slowly releases nematodes into the soil for long lasting control. The nematodes kill gnat larvae before they can mature into the annoying adults. They also may eat other pests that have a larval stage in soil. Use in indoor, greenhouse, and hydroponic applications, or outdoors in containers and gardens.
