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.
A CFC is a molecule which consists of Chlorine, Fluorine and Carbon only. Ozone is destroyed due to the formation of a chlorine free radical. For example, the CFC CCl2F2 photo â¦ -dissociates (decomposes due to UV rays) to form the chlorine free radical and this then reacts with ozone breaking it down into oxygen.
