Bendiocarb (Synonyms: NC 6897, Niomil)

Bendiocarb is a broad-spectrum carbamate insecticide and an inhibitor of acetylcholinesterase (K_i = 111 nM for the human enzyme).¹ It is active against several species, including second stage nymph German cockroaches (B. germanica; IC₅₀ = <0.5 mg/ft²) and adult yellow fever mosquitoes (A. aegypti; IC₅₀ = <0.03 mg/ft²).² It is toxic to mammalian species with an oral LD₅₀ value of 45 mg/kg for male rats and female mice, but it is metabolized and excreted rapidly and has a dermal LD₅₀ of 800 mg/kg after a 24-hour exposure. Formulations containing bendiocarb have been used in the indoor control of insects, including for mosquitoes in areas with malaria transmission.
