hi, I am very new to bee keeping, we live in Alice Springs, Central Australia. Our bees have become very 'inactive' over our very hot summer. We opened the hive (about 6 months old) and there is no honey or capped combs. Bees are still active inside the hive. Unfortunately we could not see the queen bee, but didn't want to open hive for along time. I put some sugar syrup out for them, but they have not gone to it- advise please!! Cheers
