What Scent Keeps Horseflies Away? Horseflies are painful pests that feed on the blood of all mammals, including humans. The flies trace and find their prey by targeting the prey's appearance, movement and smell. Most fly control methods target the horsefly's olfactory senses.
CFCs. Chlorofluorocarbon (CFC) is an organic compound that contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane and ethane. A common subclass is the hydrochlorofluorocarbons (HCFCs), which contain hydrogen, as well.
CFC'S or Chlorofluorocarbons are molecules which demolish the ozone layer. The ozone layer is made up of O3 or ozone molecules these reflect UV rays (harmful ultra violet ligh â¦ t) the CFC'S smash up the O3 into O2 molecules (the type we breathe) these do not reflect UV so we suffer.
