Protect your home and outdoor spaces from mosquitoes with BTI Mosquito Briquets (also known as Mosquito Dunks), a natural and effective larvicide. These floating briquets slowly release Bacillus thuringiensis israelensis (Bti), a bacteria that specifically targets and kills mosquito larvae before they develop into biting adults. Safe for people, pets, wildlife, and fish habitats, BTI Mosquito Briquets offer up to 30 days of continuous protection per dunk. Ideal for birdbaths, rain barrels, ponds, gutters, animal troughs, and anywhere water collects.
