Tackle sciarid flies (also known as fungus gnats or compost flies) with these effective, natural nematodes. These tiny, soil-dwelling worms target and eliminate the destructive larvae, protecting your houseplants, greenhouse plants, and seedlings from root damage.

How They Work

Sciarid fly nematodes are microscopic beneficial worms that seek out and infect fungus gnat larvae in the soil. Once applied, they enter the larvae through natural openings, releasing bacteria that quickly kill them. The nematodes then feed and reproduce, releasing a new generation to continue the cycle, keeping your plants safe as long as larvae are present.

Easy Application
