A widely available solution for managing mosquito larvae, these small, granular products contain Bacillus thuringiensis israelensis (Bti), a naturally occurring bacterium toxic to mosquito larvae but harmless to people, pets, and other wildlife. These products offer a targeted approach to mosquito control, disrupting the mosquito life cycle before they become biting adults.
The popularity of these Bti-containing granules stems from their ease of use and environmentally conscious approach to pest management. Unlike broad-spectrum insecticides that can negatively impact beneficial insects, Bti specifically targets mosquito larvae. Their widespread availability through home improvement retailers contributes to their accessibility for homeowners seeking to reduce mosquito populations around their properties. Their introduction marked a shift toward more biological and sustainable mosquito control strategies.
