A new study finds zero evidence that flies and cockroaches can carry the virus that causes COVID-19 from one surface to another—adding to a chorus of studies finding no role among arthropods in coronavirus transmission. In the study, researchers placed sticky and liquid-baited insect traps in and around 40 homes in Brazos, Bell, and Montgomery counties in Texas. In addition, they set 14 traps in seven homes on the day a cat or dog tested positive for SARS-CoV-2 RNA. The researchers then tested all trapped flies and cockroaches for genetic evidence of SARS-CoV-2, but no sample tested positive. (Photo by Sarah Hamer, Ph.D.)
