Re: Seen a hive beetle today!!!! Question?!
Beetles will survive the winter. Studies have revealed that even when the bees seal shb in a propolis jail, the beetle can "pipe" somehow, and the bees will feed them while they're trapped... go figure.
If you see one beetle, you've got more. Install some oil traps now, and don't worry about it any more. Depending on the physical size of my hives, I'll use 2-4 traps in each.
