What pesticides are being used on the salt marsh?

Bacillus thuringiensis var. israelensis (Bti) is a bacterium that produces a crystalline protein toxin. This protein toxin is specific to mosquito larvae and black fly larvae. Bti only works on species with an alkaline pH stomach and the specific protein receptors for the toxin. The crystals must be ingested to show a toxic effect. This very specific mode of action makes it very safe for non-target organisms present in the same environment.
