Controlling fungus gnat infestations in plant soil involves the application of Bacillus thuringiensis israelensis (Bti), a biological larvicide. This method introduces Bti-containing granules to the soil, targeting the larvae of these pests. When ingested by the fungus gnat larvae, Bti disrupts their digestive system, ultimately leading to their demise. The granules are typically soaked in water, and the resulting solution is then used to saturate the affected soil.
Utilizing Bti as a control measure presents several advantages. It offers a targeted approach, specifically affecting fungus gnat larvae while posing minimal risk to beneficial insects, pets, and humans. The effectiveness of Bti has made it a popular and environmentally conscious choice for managing fungus gnat populations in both indoor and outdoor environments. Its widespread adoption reflects a growing preference for biological pest control solutions.
