Abstract
The studies have continued in the search for potentially aversive compounds and mixtures. To date, undecenovanillylamide is the most effective substance found and is most effective in a mixture with p-dichlorobenzene. Three materials which have been tested actually appear to stimulate attack by coyotes on the treated animal. These are: Skatol (a fecal compound), Naphthalene and Thiomalic acid ( a foul sulpher-like odor).
