Hi has anyone used apigaurd on their bee hives this year ? we medicated one of our 16 hives and the bees are hanging around the outrside of the hive and will only go inside at night and this seems strange to me. we have used other medication before ( cumaflos ) and this did not happen. just wondering if anyone else has used apigaurd ? and what happened when they did. in the process of contacting my local apiary inspector at the moment to see what he says .
