For centuries, nature has provided us with solutions to our greatest challenges. One such solution is Pyrethrum, a potent insecticide derived from the dried flowers of the Chrysanthemum plant. Although Pyrethrum has been used for generations, its importance has never been greater. In today’s world, where sustainability and eco-friendly solutions are paramount, Pyrethrum stands out as a trusted, natural insecticide used for household, agriculture and post-harvest insect control due to their low mammalian toxicity, rapid knock down activity and high efficacy against a wide range of insect pests.
Natural
Pyrethrum is a natural insecticide derived from the dried flowers of Tanacetum cinerariifolium, a member of the daisy family native to East Africa and Asia.
Pyrethrum was first recognized as having insecticidal properties around 1800 in Asia and was used to kill ticks and various insects such as fleas and mosquitos. The active compounds in pyrethrum, known as pyrethrins, are highly effective in controlling a broad range of pests, making it a preferred choice for sustainable pest management.
Rapid Action
The mode of action of Pyrethrum is simple but highly effective. When Insects come into contact with Pyrethrins, these compounds disrupt the normal function of the insect’s nervous system. Specifically, Pyrethrins affect the insect’s nerve transmission by inhibiting the normal flow of sodium ions across nerve cell membranes, leading to paralysis and death of the insect within minutes of exposure.

Non-Resistance
Pyrethrum contains a group of six bio active compounds. Pyrethrins I and II, Cinerins I and II, and Jasmolins I and II. These compounds are classified as Esters of Chrysanthemic acid and Pyrethric acid, which are known for their potency in disrupting the nervous systems of insects. This complexity makes it difficult for insects to develop resistance, as they struggle to combat the multiple actions of the pyrethrins.

Additionally, the inclusion of piperonyl butoxide acts as a synergist, enhancing the potency of the pyrethrins and further increasing their effectiveness in controlling pests.
Broad Spectrum
Pyrethrum is effective against a wide range of insects in following industries.
- Agriculture: Protects crops such as vegetables, fruits, and flowers from common insect pests (Aphids, Caterpillars, Leaf Hoppers, Thrips, Mites etc)
- Home Gardening: Safeguards ornamentals and home gardens against damaging insects.
- Public Health: Often used in mosquito repellents to control insect-borne diseases like malaria and dengue in high-risk areas and as domestic insect sprays to control ants, flies etc.
- Integrated Pest Management (IPM): Pyrethrum fits seamlessly into IPM strategies by reducing reliance on synthetic chemicals and minimizing harm to beneficial insects.
Toxicity
One of the major benefits of Pyrethrum Insect Killer is its low toxicity to humans, pets, and livestock when used correctly. Pyrethrins are classified as relatively non-toxic to mammals, and when applied in the recommended concentrations, they pose minimal risk to people and animals.
However, like any pesticide, care should be taken to avoid excessive exposure. It is advised to wear protective clothing during application to reduce any risk of irritation or adverse effects.
- Non-toxic to Birds: Pyrethrum does not pose a significant risk to birds.
- Low Toxicity to Beneficial Insects: Although pyrethrum is highly effective against pests, it is relatively less toxic to many beneficial insects like bees, particularly when applied early in the morning or late evening when bees are less active.
Fate of Pyrethrum in the Environment
Pyrethrum is considered environmentally friendly due to its rapid degradation in the environment. Once applied, pyrethrins breakdown quickly under sunlight and oxygen, reducing the risk of long-term contamination. This makes it an ideal choice for eco-conscious consumers and growers.
- Biodegradable: Pyrethrum is biodegradable, so it does not accumulate in the soil or water
- Short Residual Activity: The effects of Pyrethrum Insect Killer wear off relatively quickly (1Day), minimizing its persistence in the environment and ensuring minimal disruption to ecosystems.
