The FAM evaporator consists of a lid with a rotary disc with 7 different positions, a sponge and base, for prolonged evaporation of the FORMIVAR® (only available in Germany). Not permitted for use in Spain. Dimensions 253 x 253 x 17 mm.
The sponge placed inside the evaporator completely absorbs formic acid (FORMIVAR®). With the rotary disc, according to its marked position (from 0to 7), it is possible to regulate that there are more open spaces for evaporation or less.
The amount of formic acid (FORMIVAR®) evaporated can be adjusted to the type of hive and the temperature. It is recommended to carry out a treatment as soon as possible after the honeyflow (normally in July) during 7. Before carrying out the treatment, it is advisable to have fed them.
The second treatment, normally recommended in mid-September, is left in the FAM dispenser with the formic-soaked sponge (FORMIVAR®) for 14 days. Once the days have passed, the dispenser is removed from the hive.
Do not treat if the outside temperature is greater than 30 degrees.
