Gnat Bat

Dr. Greenthumbs Gnat Bat is a biological control product specifically targeting fungus gnats (Bradysia spp.) — one of the most common and damaging cannabis pests in indoor cultivation. Fungus gnat larvae live in the top layer of growing media, feeding on root hairs, beneficial fungi, and organic matter, causing root damage, stunted growth, and opening pathways for root pathogens.

Gnat Bat likely contains Bacillus thuringiensis subspecies israelensis (Bti) or similar biological agents that specifically kill fungus gnat larvae in the growing medium without harming plants, beneficial soil organisms, or humans. Applying to soil or coco breaks the gnat lifecycle by killing larvae before they become breeding adults.

Apply as a soil drench to affected growing media. Safe for use in organic programs.
