My bees are still taking some sugar syrup from my Mann Lake Hive Top Feeders, but when they quit taking syrup and I install the inner cover, should I cut a small channel in the edge of the inner cover for an entrance/vent? As they are supplied by Mann Lake, there is a rectangular cutout in the plywood, but no channel for an entrance/vent. How is the heat supposed to get out between the inner cover and telescopic cover?
Why do you want the heat out. They need the hive to be 92 or 94 degrees??? for the brood. I have my hives in full sun in Florida with no ventilation ever.
When you consider bees in the wild...they tend to find homes with a good size cavity and a small entrance, no SBB and no upper vents. Back in the 80's we all had solid BB and unslotted inner covers. I would (as I still do now) drill a 3/4" hole in the front of some of my supers but this is more for an upper entrance than for a vent and those bees thrived. The bees do a wonderful job of regulating the temp in the hive. For your consideration.
It's true that bees prefer cavities with lower or bottom entrances in the wild, but they also usually don't choose a cavity with a 1/2" plywood top.
A notch in the cover is helpful, winter or summer. You can also put a piece of popsicle stick or other thin shim on the corners of the inner cover which will give them plenty of space for air movement without allowing other bees in.
Gary, do your bees use the notch for an upper entrance? What size notch do you use? When you shim the top cover, what size shim and do you shim one end or the entire cover.
Yes they do use it...often!
I cut about a 1/2" notch in the cover.
I use 2 "standard" wood shims and place each one on the top of super. It gives about a 1/4 inch gap all along the front side of the hive. I think it helps with ventilation.
Gary, do you have the notch on the top so they must exit/enter above the inner cover or below so they can enter directly into the hive?
