How do I know if I have deer pressure vs. insect damage on my food plot?

Deer browse cleanly through stems leaving cleanly-cut tops. Insects leave shotholes, ragged edges, or wilted stems. Deer tracks and pellets in the plot confirm deer use. Set up a small exclosure (4-foot welded wire cage over a few plants) to compare browsed vs. unbrowsed growth — clear visual confirmation of pressure source.
