Does anyone know the answer to this question.
I've looked high and low, but have not found the reason.
I know someone here knows why the documentation with Formic Pro says 'do not feed' while being treated.
Someone from a FB group called Nod to ask that question.The answer was that during product testing they saw increased bee mortality when feeding with in hive feeders,especially in the first 3 days.
Open feeding is OK.
Formic acid is a disruptive treatment and can reduce a hive's ability to defend itself, making it more prone to being robbed. Feeding syrup at that time is just compounding the risk factors.
A person may get away with it, but then again, may not. My view, feed before or after, but not during. If after, I'd leave a few days or a week for the hive to re organise, before feeding.
If the issue is timing, ie, winter is coming I only have so much time to feed plus do treatment, there is really no need to take weeks to give a hive it's winter feed. You can slam dunk 4 gallons of syrup into a hive in just a few days if the hive is healthy and a large capacity top feeder is used and set up properly. So, do that, then treat, then feed some more if needed. If the hive is noticeably suffering with mites, a less harsh treatment type could be a better choice, and most of them, feeding can be done during, with no issues.
