When Good Bees go Bad

This article was originally posted in June 2011, but contains seasonally relevant information.

Whenever there isn’t a good flow on (like now and throughout the rest of the summer) strong honey bee hives will often rob weak hives – if it gets bad enough they will completely decimate the hive that is being robbed.

This is the best video that I could find that actually showed robbing going on. Notice 2 things 1) The robber bees are climbing up the hive to get some extra elevation before they take off – this is typical in a robbing frenzy. 2) Groups of bees wrestling on the landing board, and falling off the front in clumps – those distinguish a robbing frenzy from orientation or swarming.

Time to treat for Varroa Mites

After you have harvested honey or determined that you will not be harvesting honey – it is now time (July) to treat your bees for Varroa mites.  If you have not yet obtained your treatments you need to order them right away.

For what it is worth I personally plan to use Apiguard at this time of year – because it is hot, and Apivar works better in hot weather while some other treatments become harmful at high temps.  But any of these will work if used correctly.

One word of caution – Stinky treatments like Apiguard, and Mite-away-quick-strips produce smelly fumes.  Hives need proper amounts of ventilation and must have a strong enough population to fan and ventilate the hives.  Not enough ventilation or not enough bees to fan can result in absconding (apiguard) or queen death (Miteaway) – an interuption in brood production or some brood death is not unusual or cause for alarm.
