Just like to share a remedy I discovered in northern ontario canada for mice and rabbit and all other pests , munching on my baby apple and pear trees. I placed spruce or pine branches all around my seedlings. Trees like it and pests don't.
That's interesting, I wonder if it would work on tent caterpillars? In the youtube below, Paul and Steven are hand picking them off the little tree while they discuss the ins and outs of pest control....
