The opening in the tree was about 1 foot by 1 inch

Wally instructed me to use caulk to reduce the opening to 2 inches

I placed the cone over the opening

As the bees left the tree, they could not return as the cone began functioning

The trapout began that afternoon

The bees and I enjoy this most historic setting

Hopefully, all will go well and I will do us proud and will not do too much harm to the bees in the process.
