What are the dangers of pyrethrum?

Pyrethrum is a plant that looks like the little daisy. Its flowers have a strong repellent effect known for a long time. It is often used as a natural insecticide. It is the pyrethrin which is the substance responsible for its repulsive action, with also the jasmoline, and the cinerine.

Pyrethrum has leaf with a glaucous green, it is in the form of tufts. It is 20 inches in height on average. Its flowers are 1.6 inches in diameter; they have a yellow heart and white petals. Flowering is only possible on the mountains or at high altitude (beyond 1 mile).

Originally the plant was located mainly on the Adriatic coast. It then spread rapidly thanks to its insecticidal properties. It is now widely found in Africa, especially in Kenya where crops have now become economically profitable. It helps to ward off aphids, bedbugs, leafhopper, cabbage flea beetle, crioceros, thrips, CPB larvae, sawflies.

Pyrethrum can destroy all insects in high doses. Its substance acts directly on the nervous system of cold-blooded organisms. The main problem is that it can kill bees, but also reptiles, fish.

So it is better to use it in small doses, to only repel unwanted insects. In small quantities, it only has a repellent effect sufficient to not be bothered by creeping and flying animals.

In the light, it quickly loses its effect. It must therefore be applied regularly. The best is to use it in the evening so that it lasts longer. The doses indicated on the box must be respected. It is best to wear gloves and a mask.

In the dog’s niche:

We can use pyrethrum powder to eliminate all pests in the habitat of dogs and other animals (dove, hen, …) invaded by cockroaches, fleas, mites, ticks, lice. It should not be used in the presence of the cat, it can be fatal; because it is semi synthetic.

For the House :

We can employ pyrethrum spray to fight against invasion of flies, of gnats, or mosquitoes. It will clear enough for the insects to go away, whether on land or in the air.
