Naphthalene moth balls do not deter mammalian predators at red-winged blackbird nests. Journal of Field Ornithology 59:189-191.https://hdl.handle.net/1969.6/95555Researchers often use predator repellents to deter mammalian predators from following their scent trails to nests. The effectiveness of repellents is largely unstudied. We tested naphthalene moth balls, a supposed repellent, and found them to be ineffective in deterring mammalian predators at unoccupied Red-winged Blackbird (Agelaius phoeniceus) nests that we supplemented with Northern Bobwhite (Colinus virginianus) eggs.en-USArticle
