Safety
It is one of the safest insecticides known, as it has a very low Mammalian toxicity, and is rapidly metabolised if accidentally swallowed by warm blooded animals.

Flushing action
Disturbs insects so that they move out of their hiding places and expose themselves to the insecticidal spray. Pyrethrum has greater 'flushing' power than any other commercial insecticide.

Fast knockdown and kill
Against insects, it has a very rapid paralytic action, knocking them down followed by kill.

Repellency
Pyrethrum is repellent to insects at very low concentrations, a property used in the protection of stored grain, the preparations of insect resistant packaging, and in deterring mosquitoes, both by spray-on repellents and mosquito coils. In addition, the smoke from Pyrethrum-based mosquito coils will inhibit mosquitoes from biting.

Biodegradeable, non-pollutant
Pyrethrum is rapidly degraded by sunlight into harmless breakdown products, but at the same time it can be safely stored for years in suitable containers.

Minimal insect resistance
Despite its long history of use, very few cases of insects resistance to Pyrethrum have been discovered, and these have mainly arisen as a result of cross-tolerance conferred by the insects developing resistance to another insecticide. This is in strong contrast to synthetic insecticides where innumerable cases of resistance have been discovered throughout the world.

Broad spectrum of activity
Pyrethrum is effective against a wide range of insect pests including mosquitoes, cockroaches, fleas, flies, aphids, etc. Thus a single can of a suitably formulated aerosol can be safely used against any insect found in the house or garden.
