Mosquito Bits are available from purchase at King Feed and Hardware in Wimberley, Texas 78676.

Mosquito Bits is a highly selective microbial insecticide (BTI) effective against mosquitoes in a variety of habitats. Kills the larvae of mosquitoes that transmit West Nile Virus, Zika Virus, Chikungunya, Encephalitis, Malaria, and Dengue Fever. Spread over the surface of water to release the biological mosquito larvicide. This larvicide gradually settles in the water where it is eaten by mosquito larvae growing there.

The Bits will give a quick kill of existing mosquito larvae within 24 hours. Re-apply every 7 – 14 days for maximum control. Mosquito Bits® are approved for application to areas that contain aquatic life, fish and plants. Bits may also be applied to areas used by or in contact with humans, animals, horses, livestock, pets, birds or wildlife. Apply to standing water found near the home such as water gardens, tree holes, stock tanks, animal watering troughs, rain barrels, bird baths, roof gutters, etc. Perfect for areas where standing water cannot easily be controlled such as fallen leaves, swampy areas, and vehicle tracks in turf.

Sprinkle over bromeliads, pitcher plants, and other areas where small amounts of water turn into mosquito breeding grounds. Harmless to plants, pets, beneficial insects, honeybees, fish or wildlife. Mosquito Bits are also approved and labeled as a biological control for fungus gnat larvae in planters and soils. Kills fungus gnat larvae in soil without synthetic toxins.

Mosquitoes lay their eggs in standing water, or an area known to flood. While the adult mosquito is a typical six legged, four winged, flying insect pest, their larvae only survive in an aquatic environment. Mosquito Bits are a microbial larvicide, which means that utilizing a bacterial active ingredient and controls only the larval stage of development. When applied to standing water the Bit’s release a natural soil borne bacterium, Bti (Bacillus thuringiensis subspecies israeliensis). This bacteria is ingested by the mosquito larvae within the water and soon after kills the mosquito larvae with no effect on anything else. Unlike the Mosquito Dunks® the Mosquito Bits were designed to release all of its Bti at the time of application. This feature is what has made it useful in the control of fungus gnats in addition to mosquitoes, as the Bti is easily released from the corn cob granule with water to be provided to the gnat larvae in the soil. It is the same formulation applied by professional mosquito abatement programs to sensitive habitats such as salt marshes and estuaries, it easily penetrates vegetation, and can reach fragmented, difficult to treat sites such as bromeliad “pitchers”, and hoof prints spread out over a pasture. The BTI in Mosquito Bits also provides an extremely fast and effective way to quickly kill large populations of mosquito larvae. When spread on standing water where mosquitoes breed, Mosquito Bits granules release a biological mosquito larvicide at the water’s surface. As the BTI settles in the water, hungry mosquito larvae eat the BTI and die.
