I bought 20 litres formic acid and it was 50 euros.Question is: are these better than the nassenheider type applicators?
Until proven, I will continue as I am. I think 5 litres of formic acid were not much more expensive than ten doses of this?
You may do easily formic acid pad from 65% formic acid. Big amounts you get cheaply from cattle forage chops. Formic acid is used in fresh hay forage making. 20 litre acid is here about 50 US dollars. That you may use rest of your life.
When you have reduced the hive to the 2 box position for winter, take 30-40 ml 65% formic acid and
let it absorb in some soft material like kitchen paper or toalet paper.
- To treat one box hive, use formic acid 15-20 ml.
Then put that acip paper into a litre plastic bag and put it on the hive frames. Make a wound in the plastic pad that acid can evaporate from material to the hive air.
- use rubber cloves when you handle the acid. It scalp your skin with no warning or feelings. It is fatal to bees too and that is why handle acid pads inside the plastic bag.
Treatment is repeated 3-6 times after 1-4 days.
