Pyrethroids are very toxic to cats, but not to dogs. Poisoning in cats can result in seizures, fever, ataxia and even death. Poisoning can occur if pyrethroid containing flea treatment products, which are intended for dogs, are used on cats. The livers of cats detoxify pyrethroids via glucuronidation more poorly than dogs, which is the cause of ...
Exposure to pyrethrum, the crude form of pyrethrin, [31] causes harmful health effects for mammals. Pyrethrum also has an allergenic effect that commercial pyrethroids don't have. [ 31 ] In mammals, toxic exposure to pyrethrum can lead to tongue and lip numbness, drooling , lethargy , muscle tremors , respiratory failure , vomiting , diarrhea ...
Pyrethrin based flea treatments meant for dogs can be hazardous to cats. Flea and tick ointment is also hazardous to humans. If the product comes into contact with human skin, it is recommended to wash thoroughly with soap and water.
Permethrin is toxic to cats; however, it has little effect on dogs. [4] [49] [50] Many cats die after being given flea treatments intended for dogs, or by contact with dogs having recently been treated with permethrin. [51] In cats it may induce hyperexcitability, tremors, seizures, and death. [52]
Chronic exposure to allethrins alters the plasma biochemical profile of humans and may have adverse health effects. [2] Bioallethrin has been shown to cause oxidative damage, cellular toxicity and necrosis of human lymphocytes studied in vitro. [3] It is highly toxic to fish and aquatic invertebrates.
Etofenprox is harmful if swallowed and causes moderate eye irritation. Contact with eyes, skin or clothing should be avoided. Repeated exposure to etofenprox can cause skin irritation. [3] LD 50 s are >2000 mg/kg (acute oral, rat), >2000 mg/kg (acute dermal, rat), and >5.88 mg/L (acute inhalation, rat). In rabbits, it is not a skin irritant or ...
Effects were also observed in the liver (rats, mice, and dogs), heart (dogs), and thyroid gland (rats). Some effects were also seen in the kidney (mice and rats). However, neurotoxicity was the most sensitive endpoint in the toxicology database, and other effects were generally seen in the presence of neurotoxicity and/or at higher doses.
Phenothrin, also called sumithrin and d-phenothrin, [2] is a synthetic pyrethroid that kills adult fleas and ticks.It has also been used to kill head lice in humans. d-Phenothrin is used as a component of aerosol insecticides for domestic use.
