But sometimes they can bring
too much of the woods into the houseâ¦Â
Charlotte Keller says, Thirty or so years ago I bought a live tree for myself and my son. After setting it up and getting the lights rigged, it was quite lovely. There was a knot on one of the branches, but no tree is perfect, right? Well, after the lights heated up that tree, the knot started to hatch. And pretty soon my tree came alive with baby praying mantises. I didn t notice the living tree until after Christmas when it was time to take down the decorations. Then I couldn t get that tree out of my house fast enough, decorations and all.
