Bs
Trade name: VectoLex
www.agriculture.com/go/5865

Bacillus sphaericus or Bs is a naturally occurring bacterium. Bs spores eaten by mosquito larvae release toxins into the mosquito’s gut, causing the larvae to stop eating and die. It is only effective against actively feeding larvae. Pesticide products containing Bs remain active for one to four weeks after application.

Granules are mixed with water and other substances and sprayed from the air or the ground.

Trade names: Aquabac, Bactimos,
LarvX, Teknar, VectoBac

Bacillus thuringiensis israelensis or Bti is a naturally occurring soil bacterium to control mosquito larvae. The larvae eat the Bti product, which is made up of the dormant spore form of the bacterium and an associated pure toxin. The toxin disrupts the gut in the mosquito by binding to receptor cells.

Bti is available in liquid, granular, or briquette formulations and applied by hand (with a sprayer) or aerially.

It can be applied as a liquid, pellets, or
briquettes.

Mineral oils
Trade names: Bonide, BVA2,
Golden Bear-1111 (GB-1111)

Oils, like films, are pesticides used to form a coating on the water’s surface to drown larvae, pupae, and emerging adult mosquitoes. They are specially derived from petroleum distillates and have been used for many years to kill aphids on crops and to control mosquitoes. They can be used with other mosquito-control methods.

It is available in liquid form and applied by
conventional
spraying methods.

Monomolecular film
Trade names: Agnique MMF, Arosurf
www.agriculture.com/go/5869

Monomolecular films are a nontoxic pesticide that forms a thin film on the surface of the water. The film makes it difficult for mosquito larvae, pupae, and emerging adults to attach to the water’s surface, which causes them to drown. Typically, films are active from 10 to 14 days on standing water.

It is available in liquid form and applied by
conventional
spraying methods.
