GOT VOLES? PERHAPS ANTHRAQUINONE IS THE ANSWER

Voles (Figure 1) are short, stocky rodents that often cause extensive girdling damage to a variety of tree and vine crops throughout California (Figure 2).  Vole management is often quite challenging given how numerous they can be in a given area.  In more recent years, effective management has often relied on some combination of vegetation removal, exclusion using trunk protectors, and rodenticide application.  Vegetation removal is a great tool for reducing…
