Propoxur is highly toxic to honey bees. The LD50 for bees is greater than one ug/honey bee. [citation needed] Highly toxic Acephate [25] Orthene Organophosphate: 3 days Acephate is a broad-spectrum insecticide and is highly toxic to bees and other beneficial insects. [26] Moderately toxic Azinphos-methyl [27] Guthion, Methyl-Guthion ...
Permethrin is a medication and an insecticide. [4] [5] As a medication, it is used to treat scabies and lice. [6]It is applied to the skin as a cream or lotion. [4] As an insecticide, it can be sprayed onto outer clothing or mosquito nets to kill the insects that touch them.
Tecoma stans is a nontoxic plant, but honey from its flowers is poisonous. [36] [37] Plants including Rhododendron and heathers produce the neurotoxin grayanotoxin. This is toxic to humans but not to bees. Honey from these flowers can be psychoactive, or even toxic to humans. [38] Honey can ferment and produce ethanol. Animals, such as birds ...
Permethrin and imidacloprid, which are used to kill parasites like fleas and ticks on cats and dogs, were banned in Europe in 2002 and 2018 respectively for their danger to aquatic life and ...
Cypermethrin is moderately toxic through skin contact or ingestion. It may cause irritation to the skin and eyes. Symptoms of dermal exposure include numbness, tingling, itching, burning sensation, loss of bladder control, incoordination, seizures and possible death. Pyrethroids may adversely affect the central nervous system.
An obvious side effect of using a chemical meant to kill is that one is likely to kill more than just the desired organism. Contact with a sprayed plant or "weed" can have an effect upon local wildlife, most notably insects. A cause for concern is how pests, the reason for pesticide use, are building up a resistance.
Although highly toxic to cats, permethrin is recommended as protection against mosquitoes for clothing, gear, or bed nets. [13] In an earlier report, the CDC found oil of lemon eucalyptus to be more effective than other plant-based treatments, with a similar effectiveness to low concentrations of DEET. [14]
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]
