1. Deltamethrin is currently recognized as one of the most potent public health insecticides.
Its insecticidal activity is extremely high.
Fast Knockout: Mosquitoes that come into contact with surfaces or sprays containing deltamethrin are usually knocked down within minutes to tens of minutes, with almost no chance of escape.
Long-lasting Effect: Long-lasting insecticidal mosquito nets with deltamethrin as the core ingredient can remain effective for months or even longer when used correctly,
maintaining good insecticidal effects even after multiple washes.
Extremely Low Dosage: Due to its extremely high activity, the actual concentration used is very low, yet sufficient to effectively kill target pests.
2. Mechanism of Action: One-Hit Kill
Deltamethrin acts on the nervous system of pests, causing continuous excitation of their nerves, ultimately leading to paralysis and death due to over-excitation.
It can be figuratively understood as: it “short-circuits” the pest’s nerves, rendering them unable to function normally, let alone bite people or spread diseases.
3. Mosquito coils and electric mosquito repellent liquids:
Many legitimate mosquito repellent products contain trace amounts of deltamethrin, which is continuously released for all-night protection.
Long-lasting insecticidal mosquito nets:
Recommended by the WHO as a core malaria prevention measure in malaria-prone areas such as Africa, hundreds of millions of nets have been distributed globally, saving countless lives.
Pet flea collars: Used to kill fleas and ticks on pets.
4. Deltamethrin
is thousands of times more toxic to insects than to humans because mammals (including humans) have a special enzyme that can quickly break down and metabolize deltamethrin that enters the body, rendering it inactive and excreting it.
The content in legitimate household insecticide products is far below the safety limit.
As long as you use it according to the instructions and avoid spraying it directly on food, eyes, or broken skin, it is safe.
