I treated my 4 hives for varroa in January with Oxalic Acid in drip form. I have returned four times since then to check the varroa board. 3 of the hives reacted well to the treatment, however one of the hives still shows too many varroa dead on the board. I am a little confused as why this hive has not reacted like the others. Can anyone suggest why this may be happening? And also, having tried Oxalic Acid in January can I try another Varroa treatment now?
