Hello all, it has been a warm winter here in Massachusetts. Yesterday it was warm and I opened the hive to see how my bees are doing. Inside the hive, on top of the inner cover, were a few (2-6) small grey insects. The insects were kind fat almost pear shaped ...small heads, light grey and I could not tell if there had wings. The inner cover is plastic, and the outer cover is wood. There was a good deal of condensation on the underside of the outer cover. There were a few of these insects in the wood.
I was not wearing my veil or gloves so I did not venture into the hive. I can't tell if they are in with the bees or just inside the cover.
Sounds to me like things are just fine. It's not uncommon to find various insects hanging around or in the beehives. I find ants, earwigs, beetles, spiders on a regular basis on top of the inner cover.
