Dearth?

[Jacobs]

I have placed my nectarometer back out in the last couple of days because of robbing I have seen in some of my queen-questionable hives starting Sunday. I have kept a 2 oz. honey/pint of water mix this year to give a more consistent gauge of bee interest. Today, for the first time, the bees emptied the nectarometer in less than a day (approximately 6 hours). This is the first time since late winter/early spring that the bees have shown this much interest in this honey water mix.

[Jacobs]

The bees are emptying the nectarometer at a quicker pace and are waiting for me as I come to refill the jar in the morning. Clearly, this honey water mix has more value to them now.

[Jacobs]

I am in near full dearth. The nectarometer is being emptied in less than 2 hours. I'll have to be aware of triggering robbing when I am able to work my bees again.

If we are in the dearth, should I start feeding my bees sugar water? If so, what concentration? Just inspected today and after harvesting honey they still have a fair amount of honey. I am ready to feed, just don't know when to start.

[Jacobs]

I would go with a 1:1 mix until late September and then switch to 2:1, thick syrup, if the hives are light at that point. If you keep an eye on your food stores and don't get the bees in a starvation situation, you can hold off feeding until the bees need it. Depending on the genetics of your bees, continued feeding may help with continued brood rearing and stopping/slowing the flow of nectar/thin sugar water, may cause your queen to slow down brood rearing.

Thanks Jacobs, when I inspected last I noticed they were a little low on honey stores. I started 1:1 sugar water a few days ago, as you suggested, and both hives sucked down the first bottle within 12 hours. Been adding fresh quart bottles daily since then. Should I keep feeding till they stop taking it? I have some Pro Health vitamin/essential oil supplement (supplier was out of Honey Bee Healthy) that I added. Should I keep adding that with every jar?

[Jacobs]

I would feed steadily, but probably not heavily at this point. I want the bees to have "nectar" that allows a queen to keep laying if she is inclined to, but not get "nectar" bound to the point that the bees put sugar water in every open cell and the queen has nowhere to lay. How much to feed is something you will need to figure based on how strong the hives are and how much space the bees have. A quart a day for a strong hive is probably not going to put them in a position where they become nectar bound.

I haven't been using the liquid supplements. That's not to say I won't decide to try them sometime in the future. If some have an attractive smell to the bees, you may be setting up a potential robbing frenzy. During periods of dearth, I prefer to add sugar water closer to dusk than earlier in the day. It leaves less time for larcenous bees to be active and an overnight period for the fed hive to make use of the liquid without robbing potential.

[Jacobs]

July 3rd was the first day the bees showed interest in the nectarometer this year. They really show interest in wet frames, but so far, the flow isn't so slow that cleaning frames triggers probing/robbing--yet.

Bees are emptying my nectarometer in a couple of hours or less, and are waiting for me in the morning when I bring out the pint of the day of honey water. I have watched bees deliberately work the okra bloom and the rose of sharon. I have seen them explore these blooms during dearth's in the past, but actually going in and working the blooms is new. The dearth here must be serious.

I know of two removals yesterday. Not a drop of honey in either hive. Yes a bad dearth is on.

[Jacobs]

My bees' behavior has changed from yesterday--they are now checking out anything with the smell of honey. I set up a nuc 11 days ago to try and get the daughter of a queen I like. Bees were leaving it alone until this morning. Now it is being robbed out. All queenright nucs are calm. If you are seeing a hive being heavily probed or targeted for robbing, there is a pretty good chance that you have a queen issue.
