Hi, can any one please offer some sound advice. I have Apistan in four of my hives. They have approximately 3 weeks to go before they need removing. Two hives are not in a good state, and the Apistan does not seem to be effective enough. Does any one know if I can use another set of strips once the first set comes out. I do not want to harm the hives. I use Bayvarol normally in spring, all hives have enough stores, pollen etc. I hope some one can help.
Hi. It's difficult to give advice without good information. Hence Grants response. Saying that the hives are in poor shape is not enough to go on.
Best is photos of each hive. What the bees,brood look like.
Yes, you can add other treatment after, though a waste of time/money if the interigty of the hive is stuffed.
Probably lots of deformed wing virus.
You may need to add healthy brood from the best hive to the weak ones.
Reduce entrances. High risk of robbing. Don't take long doing any checks.
An oxalic dribble could help.
