Black mesh fabric forms the base, topped by a tent of white fabric and, at the summit, a collection container—a plastic jar with an opening into another jar of alcohol.Certain essential plant oils, widely used as fragrances and flavors in the perfume and food industries, have long been reputed to repel insects.
Land Rising temperatures and shifting precipitation patterns are changing the geographic areas where mammals, birds, insects, and plants that live on land can survive—and are affecting the timing of lifecycle events, such as bud bursts, leaf drop from trees, pollination, reproduction, and bird migration.
A new report out Tuesday by the Centers for Disease Control and Prevention highlights a scary reality: Diseases spread by six- and eight-legged bugs are becoming more common.
