Common Name

Product Name Class/Use
B.s., Bacillus sphaericus Vectolex Bacterial larvicide (bacterial spores which when ingested by the larvae causes rupturing of the larval gut)
B.t.i., Bacillus thuringiensis israelensis Bactimos, Teknar, Vectobac, Aquabac Bacterial larvicide
Ethoxylate surfactant Agnique MMF Surfactant (reduces the surface tension of the water, the film makes it difficult for the larvae and pupae to attach, and blocks their breathing tubes)

1. Synthetic pyrethroids are neuropoisons, have irritatant and/or sensitizing properties, and are linked to endocrine disruption. They are extremely toxic to aquatic organisms, moderately toxic to birds,
2 Piperonyl butoxide (PBO) is one of the most commonly used synergist added to pesticide products to increase the potency. PBO is highly toxic, weakens the immune system, adversely affects reproductive function, causes liver and kidney damage and is a possible human carcinogen. PBO is relatively short-lived in the environment.
3 Organophosphate pesticides are nerve poisons, affect neurodevelopment, weaken the immune system, impair respiratory function, and are associated with increased risk of leukemia.
