Larval Mosquito Control: 

Mosquito Control will be applying larvicide to control larval mosquitoes in irrigated and wetland areas in and around Laramie on a daily basis throughout the spring and summer seasons.

Larvicides include: 

• Bacillus thuringensis israelensis (Bti)- is a bacteria used as a biological control agent for the larval stage of certain dipterans such as mosquitos, fungus gnats, and blackflies.
• Methoprene- is an insect juvenile hormone analog which as a growth regulator.
  • Used in limited areas
• BVA 2 Mosquito Larvicide Oil- When applied evenly over the water surface it rapidly interrupts the air/water interface and suffocates larvae and pupae
  • Used only in areas where Vector and Nuisance mosquito populations pose a public threat and are outside of the control window of Bti
