Arcyvert Plant Insecticide is a natural and biodegradable repellant against all crawling or flying insects. It is very effective against insects. The difference of this plant insecticide compared to traditional products is that its active principle is not a chemical compound. Indeed, it is pyrethrin, taken from the flower of pyrethrum which is part of the composition of the product. The pyrethrins which are extracted from pyrethrum are very unstable components because they are very quickly broken down by light, air and heat, which makes them easily biodegradable and therefore non-polluting materials. It is advisable to proceed by brief pressure, without prolonged spraying, on the insect whether it is flying or crawling. The persistence of action is increased in the absence of light (UV). Outdoors, it is best to use it in the evening to avoid degradation by the sun. Dangerous product. Extremely flammable aerosol and under pressure: may burst under the effect of heat. Causes serious eye irritation. Toxic to aquatic life with long lasting effects. Keep out of the reach of children. Do not smoke, spray on any source of ignition.
