Video of opossum trapping in a study of use of oral flea preventive to control Rickettsia typhi–infected fleas on reservoir opossums, Galveston, Texas, USA, 2023–2024. A cage trap is set over a white towel and baited with canned cat food mixed with a crushed 270-mg spinosad flea control tablet (Elanco, https://farmanimal.elanco.com). As the opossum enters the trap and walks toward the bowl of spinosad-impregnated food, it steps on the trap’s trigger plate, which actuates the closing of the trap door. In this particular trapping, the first of these experiments, the food bowl is almost tipped over by the startled opossum. Subsequent experiments used a commercially available cat food bowl to avoid easily tipping over the food contents.
