A trap can also be placed under this shingle, because voles are readily attracted to shingles or pieces of plywood placed on the ground. Shingles should be bent to form an A-shaped roof. Plywood or flat material should have small blocks under the comer to allow for a crawl space. These items can also serve as bait sites. Leave in place a few days before baiting to allow the animals to become accustomed to them.
Cats are natural enemies of voles.
Keeping a cat near vole-infested areas will help reduce these pests. Rutgers Cooperative Extension is an Equal Opportunity Employer. If Plants Could Talk'' 2000 William T. Hlubik , Rutgers, The State University of New Jersey.
