According to surveys of wildlife control operators (WCO), problems with raccoons (Procyon lotor) con-sistently rank among the top complaints for property owners. Among the more serious behaviors of fe-male raccoons is their propensity to invade human-occupied structures to raise young. Distressed property owners frequently respond using lethal means, either on their own or through hiring WCOs. Even if live-captured and legally released, the handling of raccoons may result in injuries and potentially cause fe-males to abandon young. Eviction fluids, developed in the early 1990s, are designed to smell like a male raccoon and therefore cause a nursing raccoon to leave the den with her young. Wildlife control operators use eviction fluid primarily to evict a female and her young from an inaccessible location. Though the precise formulas are not disclosed by manufacturers, the fluids consist of the glands and urine of male raccoons coupled with a preservative. We evaluated the efficacy of 2 raccoon eviction fluids to evict fe-male raccoons with young from chimneys. Though our sample size was small (n =15), we found that eviction fluids merit further investigation as a viable non-lethal repellent for raccoons in human-occupied structures.
