1 teaspoon of mosquito bits per gallon of water is the recommended ratio for effective mosquito control.

Mosquito bits are small, biodegradable granules containing Bacillus thuringiensis israelensis (Bti), a naturally occurring bacterium that kills mosquito larvae. This treatment is safe for humans, pets, and beneficial insects when used as directed. The 1 teaspoon per gallon ratio ensures optimal distribution of Bti in standing water where mosquitoes breed.

Application methods for mosquito bits

  • Standing water: Sprinkle directly into ponds, birdbaths, or rain barrels
  • Soil drench: Mix with water and apply to potted plants or garden beds
  • Fungus gnat control: Apply to soil surface in indoor plants

Comparison of mosquito control products

Product Application Rate Duration of Effectiveness Best Use
Mosquito Bits 1 tsp per gallon 7-14 days Standing water, soil
Mosquito Dunks 1 dunk per 100 sq ft 30 days Larger water bodies
Liquid Bti 4-8 tsp per gallon 24-48 hours Large-scale treatment

Safety and environmental considerations

Bti specifically targets mosquito larvae and is non-toxic to humans, pets, fish, and wildlife. It breaks down naturally in the environment without leaving harmful residues. For maximum effectiveness, reapply every 7-14 days or after heavy rainfall, which may dilute the treatment in outdoor water sources.
