Foundation perimeter treatments with liquid residual pesticides can therefore be an effective control. They feed mostly at night and are attracted to porch lights and other exterior lights. Outdoors, they are actually considered beneficial because they feed on insect larvae. This can stain fabrics, carpeting, wallpaper and other household items. In late winter or early spring, they are often noticed sluggishly flying about after emerging from these spots. They feed on evergreens, fruit trees, strawberry, rhododendron, rose and other plants. VEGETATIVE COMMUNITIES AS INDICATORS OF GROUND BEETLE (COLEOPTERA: CARABIDAE) DIVERSITY BY ALAN D. YANAHAN THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology in the Graduate College of the University of Illinois at Urbana-Champaign, 2013 Urbana, Illinois Master’s Committee: Dr. Steven J.

Larval (first immature stage) mites have three pairs of legs. ), are common around trash dumps, and occasionally do incidental damage to fabrics. The weevils can be excluded by sealing cracks and gaps in structures. At night, place a light source such as an unshaded lamp or drop light in the middle of the room. This sort of data can be useful in seeing concentrations of a particular species over the continent as well as revealing possible migratory patterns over a species' given lifespan. While it has done its share to save valuable crops, it also invades structures each fall in greater numbers than those of native lady beetles. Although springtails may enter homes in large numbers, they usually die indoors, lacking sufficient moisture, humidity and food for survival. -invaded (invaded) and un-invaded (native) habitats in Rocky Mountain savannas.
