My method is similar like Apiwarol in Poland. But apiwarol is more expensive.
I buy Tactic 12,5% and I use varomor like Ukrainian but I made it myself. This is link for Ukrainian varomor:

обрабатываю от клещаThis method is very fast and nice ;)
Recepture on fluid for 80 hives:
92 cm3 kerosene or paraffin oil
8 cm3 taktic (1cm3 of clean amitraz)
Varormor is calibrated on 1.2 cm3 of liquid, evaporated to the hive when you press. One press on one hives.
Evaporated amitraz on one hives is 12 mg like in Polish Apiwarol. But this method is very cheep, faster and very effective.
I use Varromor after the last honey harvest. Four times every four days. To close varoa cycle(1- day 0, 2- day 4, 3- day 8, 4- day 12). All Varoa come out at that time with the young bees. In this time I killed about 90-95% varroa. And last time in October or November when in hive is no brood I use once. In this time I kill all varroa. Maybe can stay max 5 varroa in hive. And I have stillness to the next year. Of course you can use varomor one time when is no brood in hive but when is small infection of varroa (1-300 pieces in October). Of course you must evaporated when all bees are in hives (evening) and when temperature is above 10 Celsius (50 F).
You need 10-15 second to one hive ;) That is very fast method and relations are used less amitraz. You can lie on the bottom of the sheet greased with oil and count after two hours, the amount of varroa. And you know how many was in hive.
