Instructions for use

The resulting solution is filled into a smoke gun. Thanks to kerosene, the smoke will be drier and more penetrating. The jet is served twice with a time interval.
In advance, paper smeared with petroleum jelly is lined at the bottom of the hive. This technique is necessary, because the ticks are showered while still alive. Don’t expect an immediate effect. The result will be visible in 12 hours.
When treating bees with an aqueous solution of Bivarool using a smoke gun, kerosene can be replaced with vegetable oil. Both methods are repeated in a week.
