Controlling Mosquito Larvae

When Collier Mosquito Control District can control mosquito larvae — the juvenile stage of the insect in water — larval control materials are chosen that specifically target the larvae. Interrupting the lifecycle of the mosquito is one of the key components in the District’s Integrated Mosquito Management (IMM) program. Interrupting the mosquito lifecycle results in fewer flying, biting adult mosquitoes.

How it Works

The District uses two materials for mosquito larvae control including, Bacillus thuringiensis israelensis (Bti) and spinosad. Both materials are used in a liquid and a granular form by truck, helicopter, and drone.

The District’s Buffalo Turbine disperses a fine mist of Bti and is used primarily in heavily populated areas where the Aedes aegypti mosquito breeds in containers of standing water near homes and businesses. This mosquito species can transmit Zika, Yellow Fever, Dengue and Chikungunya.

Additionally, the District is equipped to distribute larval control by air. Both helicopters and drones disperse liquid and granular larvicide materials.

Both Bti and spinosad are derived from soil bacterium and are the District’s larval control materials by choice for two reasons: first, these naturally occurring materials pose no threat to non-target insects, animals, plants, fish, or people; secondly, they are highly effective, with reductions in mosquito populations noted within 24 hours after application.
