What are pyrethrins?
Pyrethrins are pesticides found naturally in some chrysanthemum flowers. They are a mixture of six chemicals that are toxic to insects. Pyrethrins are commonly used to control mosquitoes, fleas, flies, moths, ants, and many other pests.
Pyrethrins are generally separated from the flowers. However, they typically contain impurities from the flower. Whole, crushed flowers are known as pyrethrum powder.
Pyrethrins have been registered for use in pesticides since the 1950's. They have since been used as models to produce longer lasting chemicals called pyrethroids, which are man-made.
Pyrethrin is a kind of broad-spectrum insecticide that can control a variety of pests. Its insecticidal toxicity is 10~100 times higher than that of older generation insecticides such as organochlorine, organophosphorus and carbamate. Pyrethroids have a strong contact killing effect on insects, and some varieties have both gastric toxicity and fumigation effects, but none have an endothermic effect. Its mechanism of action is to disrupt the normal physiology of insect nerves, causing them to go from excitement, spasms to paralysis and death. Pyrethroid is relatively safe for humans and animals due to its small dosage and low concentration, and has minimal environmental pollution. Its main drawbacks are high toxicity to fish and harm to certain beneficial insects. Long term repeated use can also lead to pest resistance.

How do pyrethrin insecticides work?
1.Pyrethrins provide a rapid knockdown of insects. Pyrethrins have low toxicity to warm blooded animals but is a powerful insect repellent. Pyrethrins target the central nervous system of insects providing a quick kill.
2.Pyrethrins excite the nervous system of insects that touch or eat it. This quickly leads to paralysis and ultimately their death. Pyrethrins are often mixed with another chemical to increase their effect. This second chemical is known as a synergis.

Are pyrethrins safe?
Pyrethrins (Pyrethrums) have been used effectively to control insects and decomposes quickly in the environment making it environmentally friendly.
According to the USDA, synergized pyrethrum is one of the safest insecticides for use in food manufacturing plants. Pyrethrins are approved by the USDA around foodstuffs. Pyrethrins can be used in manufacturer facilities, homes, and around animals. It is often used where more dangerous pesticides cannot be used. Pyrethrins and its synergists very quickly disintegrate in the air and sunlight and is biodegradable. This assures no excessive build-up of insecticides that are dispensed.Can insects get immune to pyrethrins?
Insect resistance is not an issue. Because pyrethrins decompose quickly in the environment, pyrethrin has been used for insect control for decades. There is virtually no insect resistance, so it is used in insect control, in a broad spectrum of settings.
Repellent and Insecticidal Properties
Besides pyrethrins knock-down on contact property, it also repels insects. This inherent repellency of insects has been observed in food establishments like restaurants in fly control programs using pyrethrins. Many flies that are not killed on contact will be found dead on places like windowsills or near doorways. The flies are repellled by the aerozolized area of pyrethrin and seek the outside.
Pyrethrin Uses
1. Aerosols
Typical pyrethrins in aerosols such as, CB 80 and PT 565 provide contact kill and flushing actions. They come in aerosol cans with a tip attached to flush the insects out of their hiding places.
2. Fogging Materials
Pyrethrins have long been the most popular fogging compounds for fogging entire areas with foggers.
(a) Oil Based Pyrethrins are used in all foggers. Most of the time they are ready to use (RTU) pyrethrin products, but some may be diluted.

(b) Water Based Pyrethrins (Emusifiables) are used in cold-ULV foggers and mosquito misting systems. Water based pyrethrins may be mixed with water or used as a ready to use product.
