There are two types of synthetic pyrethroids 1) light unstable and 2) light stable synthetics. The first class, of which bioresmethrin or phenothrin are examples, were discovered in different laboratories around the world. These fast acting agents are primary used for specialty purposes in non-agricultural markets like public health, animal health and consumer. The preparation of a the first slight unstable synthetic pyrethroid, bioresmethrin, is attributed to Dr. Michael Elliott at the UK Agricultural Laboratory at Rothamstead England in 1967. The second class of which permethrin cypermethrin and deltamethrin are examples were also discovered by Dr. Elliott in the early 1970's. These halogenated derivatives proved to be light stable. Licenses for commercial use of these discoveries were made to several chemical companies who developed them for both agricultural and specialty uses.

What is something synthetic?
If you're talking about synthetic elements, something like Californium would count. You can spot these synthetic elements at the bottom of the periodic table under "Lanthanides and Actanides". Basically, it's anything over Mass Number 94 and they decay very quickly. If you're talking about the other sort of synthetic "substance", then I suggest Nylon or Polyester.

What is permethrin typically used for?
Permethrin is mostly used as a pesticide. It is particularly effective against insects and arachnids. It is also used as an insect repellent. Although highly toxic to our feline friends the cat, it has a low toxicity to most mammals. Care should be taken when disposing of this chemical as it is also highly toxic to fish. Like other members of the pyrethroids family of synthetic chemicals it is essentially a neurotoxin and should be used with care.
What pesticide is used to control woodworm?
Permethrin is a pesticide which is used to control woodworm.Specifically, the pesticide can be considered an acaricide and an insecticide since it respectively controls such arachnids as mites and ticks on the one hand and insects on the other. It eliminates pests by the neuron membrane-affecting functions of its synthetic chemicals (pyrethroids). It generally will not be harmful to birds and mammals even though it is toxic to cats and fish.
Will permethrin kill yellow jackets?
Permethrin does kill yellow jackets as well as hornets, ground bees, wasps, and other stinging insects. You can discourage yellow jackets from nesting in trees and shrubbery around your yard by spraying them with permethrin as well.
What is stronger then permethrin for bed bugs?
Dichloorvos and DDT more effective, but is harmful to other organisms.
How regular can you use Permethrin cream without side effects?
Permethrin is designed to kill insects and other non-mammals. It is not very toxic for humans. It is also poorply absorbed through the skin. Maybe taking a bath in concentrated permethrin could kill you, but any permethrin cream designed for use in humans probably has very little chance of doing anything that is not designed to. (Especially if you follow the directions). -Zach

Will permethrin kill mature bagworms?
