My partner became a beekeeper ~three years ago. He now has two hives. I help him conduct hive inspections when available.
Yes, the honeybees will be attracted to the open jar of honey. (They live on their own honey production). Putting a jar of honey out can potentially create two risks.
1. Honeybees are challenged by a lack of balance. For example, we have a bird bath just outside of our hives. It’s filled with pebbles and a shallow level of water. The pebbles provide landing spots for the bees. Even with this set-up, we still have some that drown.
Placing a jar of honey out is highly risky.
2. I recently read that there is potential danger to a hive from feeding them honey from another source. So, unless the honey source is from that hive, it may create a risk to the bees’ health.
