It was explained to me by a wildlife biologist that eggs contain a sulfur compound that is chemically similar to the deer alarm scent. That's why eggs work when other smelly substances don't. The deer probably thought the fish was a new seasoning.|

After the discussion about using egg spray to repel deer from the orchard, I had this cool idea of using fish emulsion spray to keep them away. It seems that if the odor of egg repels deer, the odor of fish emulsion on the foliage ought to drive them out of the county. And besides, you might get some foliar feeding benefits.
