I burnt the local fauna around the tree 3 weeks ago unaware of the bees presence. Yesterday while in the area, I saw the bees for the first time. The hole is about a foot wide and the bees are exposed. I won’t be here when the temp drop again, so I need to get of them promto. No fuel of any kind is going in the hole for the trees sake. I was thinking tannerite ? Any ideas from the HT crowd. I’ll take pic and post soon.
