Flies are nuisance to humans in everyday life, they get in your eyes, up your nose and some of us occasionally have the distasteful pleasure of swallowing one; however, flies play an important role in the environment from maggots that break down organic matter in garbage to pollination of flowers in crops, so total eradication is not feasible for nature.

Create an artificial pheromone that repels flies but does not harm environment, people and the flies. The distribution system needs to be odourless to humans and be able to be clipped onto clothing, hat or belt. This is an alternative to short lasting repellents that smell and give people bad health side effects such as asthma, headaches and migraines
