Pyrethrum: an effective and safe way to control insects

Pyrethrum is a powder that is obtained from the flower heads of chamomile, such as Dalmatian, Caucasian or Persian. This powder is toxic to insects, but is practically harmless to humans. The active principle of Pyrethrum is pyrethrins contained in the powder in an amount of at least 0.3%.

Pyrethrum is an effective insect repellent. It quickly causes muscle paralysis in insects and enters their body through the outer integument. The powder is sprayed indoors at the rate of 4-5 g per 1 liter (to kill flies and mosquitoes), 10-12 g per 1 liter (to kill moths) or applied to surfaces at the rate of 20-23 g per 1 square meter (against bedbugs , flies, mosquitoes and moths). To kill cockroaches, a significantly larger dosage of the drug is required, so it is used less frequently.

It is recommended to collect and burn poisoned insects to prevent their reappearance. The toxic effect of the powder sprayed on the surface lasts no more than 1-2 days.

In addition to natural chamomile powder, various analogues of pyrethrins have been prepared under the general name pyrethroids, which have similar properties and are used for industrial and agricultural purposes. However, unlike natural powder, pyrethroids can have harmful effects on people and animals and should be used with caution and as directed.

In conclusion, Pyrethrum is an effective and safe way to control insects. It can be used both at home and for industrial and agricultural purposes. It should be remembered that correct dosage and use are key factors to achieve optimal results and minimize harm to the environment and human health.
