My husband and I recently moved onto a 5 acre property with 4 fruit trees on it. We are brand new to permaculture and while we love everything we are learning about it, we are also a bit overwhelmed with all the information. Today I found tent caterpillars (I assume by the way they built their "nests") in more places than I'd like all over our trees. After all, I painstakingly went from branch to branch a few weeks ago scraping away every egg nest I could find. I know that "the problem is the solution" and that I need to get plants growing under the trees that will attract predatory birds/insects and make the tees healthier, but what are my short-term options? Is there anything natural I can do to get rid these nasties before they get bigger?
