dc.description.abstract | Leeches are an important part of many freshwater ecosystems, but they can be a nuisance and a health hazard for humans who want to enjoy a swim. To keep them off the legs of swimmers, we set out to find effective repellent s that were also relatively safe for the environment. We applied five treatments (negative control, 5% distilled white vinegar, 40% DEET insect repellent, 30% Lemon Eucalyptus oil insect repellent , chewing tobacco and water mixture) to bait and counted how many freshwater ribbon leeches (Erpobdella obscura) attached to the bait for each treatment. We hypothesized that all treatments would be more effective than the control at repelling leeches, and specifically predicted that tobacco would be most effective. We found that vinegar and the control were not effective and the other three treatments were effective; no relationship was found between a repellent's acidity and its effectiveness. Going forward in the quest to protect swimmers, it would be beneficial to test the three successful repellents on bloodsucking leeches as we only had access to a jawless species that dines on invertebrates. | |
