What Is Pyrethrin？

Pyrethrin, also known as pyrethrum, is a compound extracted from the chrysanthemum flower — a plant native to northeastern Europe, Asia and Eastern Africa, though it is grown throughout the world. In fact, many North Americans know this plant as a mum, a decorative autumn flower. These plants contain pyrethrin, which is used by the plant as a natural defense mechanism to protect against insects and other pest animals. 

Pyrethrin affects an insect’s nervous system through a deadly toxic effect. Almost immediately upon contact with this compound, the insect dies from a form of paralysis. 

This effect is what makes pyrethrin a highly effective insecticide.

Pyrethrins, which are found in the leaves, stems and especially the flowers of pyrethrum, a plant in the daisy family, have a strong poisoning effect on insects. 

The flowers of pyrethrum are collected and dried, and mixed with wood chips and spices to make a fumigant, and then ignited, the pyrethrins can be emitted with the smoke, and once the flying mosquitoes come into contact with it, they will be poisoned, and this kind of fumigant is an excellent natural "mosquito incense".

Pyrethroid insecticide spectrum is relatively wide, able to kill many health and agriculture and forestry pests, the toxicity of people and other warm-blooded animals is also very small, no residual pollution of the environment. Its disadvantage is that it has poor stability to light, and it is easy to decompose and fail once it meets the sunlight irradiation, so it is only suitable for indoor use to prevent and control mosquitoes, flies, cockroaches and other health pests, and it is not suitable for spraying as a pesticide in the field.

From the 1920s, chemists on the pyrethroid extraction, separation and other research, to the 40s has basically clarified its molecular structure, it is a 3-carbon ring containing ester compounds.

Pyrethrin is a natural insecticide that is derived from the flowers of chrysanthemum plants.

 It is one of the oldest and safest insecticides that have been used for centuries to control a wide range of insects, including mosquitoes, flies, cockroaches, and other pests. 

Pyrethrin works by attacking the nervous system of insects, which leads to paralysis and death.

Note: Our Pyrethrins are production-type ingredients, highly concentrated.

One of the most significant benefits of pyrethrin is its low toxicity to humans and pets. It is considered safe for use in food processing plants and other sensitive areas, such as hospitals and schools. Pyrethrin is also safe for use on fruits and vegetables, making it an ideal insecticide for organic farming.

Pyrethrin is available in many forms, including sprays, dusts, and foggers. It is easy to use and can be applied directly to plants or surfaces where insects are present.

It is also effective against many insect species, making it a versatile insecticide.

Another advantage of pyrethrin is that it is biodegradable, meaning that it breaks down naturally over time. This makes it an environmentally friendly alternative to many synthetic insecticides that can persist in the environment for years.

Despite its many benefits, pyrethrin is not without its drawbacks. One of the main limitations of pyrethrin is that it has a relatively short residual effect. This means that it does not provide long-term protection against insects and may require repeated applications to maintain its effectiveness.

Another challenge with pyrethrin is the development of insect resistance. Insects can develop resistance to pyrethrin over time, which reduces its effectiveness. To address this matter, it is recommended to rotate the use of pyrethrin with other insecticides to prevent the development of resistance.

Pyrethrin is a safe and effective natural insecticide that has been used for centuries. Its low toxicity to humans and pets, biodegradability, and versatility make it an excellent alternative to many synthetic insecticides. However, its short residual effect and the development of insect resistance are two potential limitations that should be considered when using pyrethrin for insect control.

Overall, pyrethrin is a valuable tool in the fight against insects and a critical component of integrated pest management programs.
