Fly Control and Fly Screens Fly Control: The average fly maintains approx.. 6 million bacteria on it's external surface and 25 million bacteria internally. Flies are fluid feeders, so they need to liquidise solid food in order to consume it. Fly Control Units We can supply a range of fly control units which include the Cobra insect control units which, due to their unique translucent covers, attract more and catch all types of flying insects. When they land on unprotected food, they regurgitate saliva and enzymes onto the food. In the process they vomit stomach contents and defecate onto the food. Fly control is Essential in preventing the spread of disease and food poisoning organisms.
