When Mike Stringham, professor of entomology at North Carolina State University, investigated the use of clear plastic water bags as a fly deterrent, he encountered just such a situation.
Stringham conducted a week field trial by installing commercial, water-based optical fly repellents on two egg stumpmulching.barg: tree.
