Carbaryl is a cholinesterase inhibitor and is toxic to humans. It is classified as a likely human carcinogen by the United States Environmental Protection Agency (EPA.) [13] The oral LD 50 is 250 to 850 mg/kg for rats and 100 to 650 mg/kg for mice. [8] Carbaryl can be produced using methyl isocyanate (MIC) as an intermediary. [5]
A few additional screening questions about the patient's work and home environment, in addition to a typical health questionnaire, can indicate whether there was a potential pesticide poisoning.

In sufficient quantities, such chemicals can poison and even kill the bee. The effects of alcohol on bees have long been recognized. For example, John Cumming described the effect in an 1864 publication on beekeeping. [1] When bees become intoxicated from ethanol consumption or poisoned with other chemicals, their balance is affected.
Bees have been shown to be particularly sensitive to pyrethrin, with fatal doses as small as 0.02 micrograms. [1] Due to this sensitivity and pollinator decline, pyrethrins are recommended to be applied at night to avoid typical pollinating hours, and in liquid rather than dust form. [38]
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 this difference. [ 15 ]
