Protective period

A month or more depending on pest population condition.

Speed of action

Most rodents are exposed within the first week after swallowing, some species within the second week.

Spectrum of action

Common vole, Eat European vole, public vole, and water vole.


Efficient when used alone. Interval between treatment rodenticides and treatment with other pesticides - minimum 2 weeks. It is unfeasible to use it together with other rodenticides.

0.015% in bait (30 ml/kg of bait)
10 g of bait to be put into hole

1.0 to 6.0 kg/ha

Wheat grain, husked oats, slices (1-2 cm) of carrot, potato, sugar beet, or apple are used as a bait. Bait to be applied manually into holes using dedicated applicators at rodent density of 10-20 holes/ha to 600 holes/ha for common, East European and public vole, up to 300 holes/ha for water vole, as necessary, in any case the treatment interval shall be min. 2 weeks, max. 2 treatments in succession with the same bait material. -(-)


Water vole

20 g of bait to be put into hole

Application technique. Bait preparation
Mix the bait base material with the preparation (30 ml of preparation per 1 kg of bait) in the treatment unit or metal pan. Wheat grain steeped before germination and surface dried shall be used as bait base material (if contamination of plantings is to be avoided, use steamed grain, or other known bait materials without hard scales, peelings or trash). Hold the preparation mixed with the bait base material for soaking (at above +15⁰C and draught – up to 3 hours, at lower temperatures – up to 24 hours), and stir before use.
Bait eatability is improved by adding and thoroughly stirring fine salt (0.2-0.3% wt. of bait mass) or sugar (2-4%). Consumption rate: 30 ml of preparation per 1 kg of bait. Put the ready-to-use bait into a closed container intended for bait storage or transport to the point of application.
Due to specific application conditions, the preparation is not of hazard to bees.
Toxic to fish.
Do not apply the preparation within the sanitary zone of fishery water bodies 500 m away from the flood line in case of maximum floodwater level, but not closer than 2 km to the existing banks.
