Permethrin is a medication and an insecticide. [6] [7] As a medication, it is used to treat scabies and lice. [8]It is applied to the skin as a cream or lotion. [6] As an insecticide, it can be sprayed onto outer clothing or mosquito nets to kill the insects that touch them.
Herbicides such as copper sulfate that are applied to water to kill plants are toxic to fish and other water animals at concentrations similar to those used to kill the plants. Repeated exposure to sublethal doses of some pesticides can cause physiological and behavioral changes that reduce fish populations, such as abandonment of nests and ...
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. Phytophagous insects are able to build up this resistance because they are easily capable of evolutionary diversification and adaptation . [ 49 ]
Environmental groups are calling for the removal of these pesticides from flea and tick treatment for dogs and cats.
The metabolism of bees and humans is sufficiently different that bees can safely collect nectars from plants that contain compounds toxic to humans. The honey produced by bees from these toxic nectars can be poisonous if consumed by humans. In addition, natural processes can introduce toxic substances into honey produced from nontoxic nectar.
