The efficacies of induced backyard cleanups of mosquito development sites via 3 different literature treatments were studied in low- and middle-income neighborhoods in Gainesville and Tallahassee, FL, during July and August 1993. Results indicated that 4-color-process literature significantly reduced the number of artificial containers with or without active mosquito development in both economic areas in both geographic locations compared to no literature or black-and-white literature treatments. More importantly, there were no differences between residences receiving the black-and-white literature and residences given no literature.
