Went to help a friend find and mark her queen today in the glorious weather - all successful. However she pulled off some drone brood that was sticking out and we checked it later. It seems that there are about 4 mites average per larva. Neither of us have done this type of check before so we think that is rather a lot but are not sure. See photo. Do you recommend immediate treatment for the varroa? They are on brood and a half. She would like to use MAQS as it does not effect the honey and the temperature is good but is not sure if it is really necessary. Bearing in mind that we are just at the start of done brood up here - I don't have any yet. She is worried that if she left till autumn treatment it would be too late. Any help would be great. Thanks from Bridget and Sally
