Bifenthrin — toxicity, side effects, diseases and environmental impacts

Friday, December 08, 2017 by Michelle Simmons

Bifenthrin is an insecticide that belongs to the pyrethroid group used against pests, such as fire ants, blue grass weevil, army worms, cut worms, centipedes, crickets, earwigs, millipedes, sowbugs, mole crickets, ticks, fleas, and grasshoppers. It is usually applied on non-cropped areas, such as lawns, athletic fields, ornamentals, residences, and commercial buildings. It works by interfering the functions of the insect’s nervous system when they eat or touch it, causing paralysis. Bifenthrin has the molecular formula of C₂₃H₂₂ClF₃O₂.

List of known side effects

A person could be exposed to bifenthrin if touched, ingested, or inhaled. When the chemical gets on the skin, bifenthrin can cause tingling, itching, burning, or numbness on the affected area. When inhaled, it can irritate the nose, throat, and lungs. Moreover, when large amounts of bifenthrin are ingested, it can cause sore throat, nausea, abdominal pain, and vomiting almost immediately. Bifenthrin is also classified as a possible human carcinogen by the U.S. Environmental Protection Agency.

Bifenthrin can be poisonous to humans. Since it is a pyrethroid compound, it has similar symptoms of poisoning with other pyrethroid compounds. These include irritation of the skin and eyes, irritability to sound or touch, abnormal facial sensation, sensation of prickling, tingling, or creeping on skin, numbness, headache, dizziness, nausea, vomiting, diarrhea, excessive salivation, and fatigue. In severe cases of bifenthrin poisoning, it may cause fluid in the lungs and muscle twitching.

For its environmental side effects, the chemical can bind to soil and can potentially contaminate surface waters through runoff. It is extremely toxic to the aquatic environment and bees.

Body systems affected by bifenthrin

The body systems negatively affected by bifenthrin include the integumentary, ocular, respiratory, nervous, digestive, excretory, and muscular systesms.

Items that can contain bifenthrin

Some of the trade names for products that contain acephate include Talstar, Bifenthrine, Brigade, Capture, FMC 54800, OMS3024, Torant (with Clofentezine), Zipak (with Amitraz), Gala 10 EC, Gyro, Starion Flo, Talstar Flo, and Talstar 8 SC. Products that contain bifenthrin come in different forms, such as sprays, granules, and aerosols.

How to avoid bifenthrin

Exposure to bifenthrin can be limited by reading the product label and following all of the directions. In addition, refrain from smoking, eating, or drinking without washing hands after using a product that contains the chemical.
