Mosquito Bits®

Mosquito Bits® are a biological control that kills mosquito larvae. It is now also approved for the control of fungus gnats, which usually populate potting soils for house and container plants. They are Corn cob granules coated in Bti, the Bits (do not last long) provide a punch, turning water black with larvae, to a clear pool void of future mosquitoes. The Mosquito Bits® are now labeled to control Fungus Gnats in plant beds or pots! Utilizing a similar mode of action for control of mosquito larvae, Mosquito Bits, either sprinkled on the soils surface or mixed with potting soil prior to planting will kill fungus gnat larvae with the same safety and target specific control offered for mosquito larvae. EPA registration numbers: 704657 – 6218-73 704659 – 6218-73
The active ingredient in Mosquito Bits is a biological larvacide called BTI (Bacillus thuringiensis subspecies israelensis). BTI is a naturally occurring bacterium that’s deadly to both mosquito larvae and fungus gnat larvae.

Fungus gnats can infest potted plants, and the insects can be difficult to control, according to a news release. Fungus gnats lay their eggs in the potting soil of houseplants and container plants, and the larvae live in the moist potting mix. In the larval stage, the fungus gnat maggots can cause plant damage by eating plant roots. After about two to three weeks, the fungus gnat maggots pupate to become the tiny black adult gnats that often take flight in a cloud of insects when a potted plant is moved. To control fungus gnats, simply shake the granular Mosquito Bits onto the potting soil in houseplants and other container-grown plants.

Mosquito Bits can also be mixed with potting soil prior to planting. When the plants are watered, the BTI in the Mosquito Bits are released. After subsequent watering, the BTI is washed below the soil surface. Fungus gnat larvae feed on the BTI and die.
