Gnat Smack is a 5 kg package of beneficial nematodes designed for biological control of fungus gnat larvae in soil, coco coir, rockwool, and hydroponic systems. The nematodes actively seek out and infect larvae, releasing bacteria that kill the host within 48 hours and preventing adult emergence. This disrupts the gnat life cycle effectively. Safe for plants, pollinators, earthworms, and the environment, with no chemical residues. Apply by mixing with water at 3-5 million nematodes per square meter as a soil drench. Store refrigerated for viability. Ideal for integrated pest management in commercial and hobby grows.
