No, there are no known risks. Revira contains no chemical additives. The granules are made from ceramic material, similar to the clay pebbles used in gardening, and are used as a standard soil amendment making them completely safe for humans, animals, plants, and the environment. If any Revira residue remains, it can safely be added to compost or used as a soil conditioner.

Revira works best on animals in normal grazing behavior. Wildlife being chased, animals in heat, or those during hunting season may be harder to deter. When used correctly, Revira has shown a high deterrent effect — field reports and studies from Germany indicate up to 95% reduction in wildlife-related road accidents in areas where Revira was properly installed. The effect lasts 3–6 months.

Revira is used as a deterrent line because animals should detect the signals before reaching the area to be protected. For this reason, the granules are spread in a strip around or in front of the area, rather than across the entire area.

No, there are no known risks. Revira does not contain chemical additives. The granulate is ceramic (like Leca) and is used as a normal soil improver - completely harmless to humans, animals, plants and the environment. Should any Revira residues remain, it is permissible to put it in the compost or use it as a soil improver.

Yes, Revira can be effective against sheep. Sheep are sensitive to the signals emitted by Revira and will generally avoid areas where it has been applied. However, results may vary depending on the temperament of the sheep and grazing conditions.
