For odors to work, certain environmental conditions have to be met. Townsend s voles, Microtus townsendii, avoid a repellent odor if no cover is available. With cover present, they feed whether or not the area is scented. Therefore, for effective area repellents, the pest rodent should be able to retreat to unscented areas in preferred habitat such as sufficient cover (Merkens etal, 1991 Table 13.2).
