Flies have been a menace to mankind since biblical times. The importance of fly control is paramount, if not for health reasons, then for financial ones.
Poultry losses run into the millions of dollars annually; and cattle weight has known to drop 10-15% due to the pesky fly.
For every fly seen, there is an estimated 19 more hidden from view. This means that humans normally do not see 95% of the flies that are present at an infestation. Also, one pair of flies can produce more than one million offspring in as little as six to eight weeks. Flies spread diseases readily because they move quickly from rotting, disease laden garbage (among other disease laden product) to exposed food and utensils.
Flies easily collect and transport diseases, since they live and breed in disgusting environments. The hair on the flies body collect the bacteria and organisms. This process can cause millions of microorganisms quickly transferred from the fly to the exposed objects. Flies also have disgusting eating habits and happily vomit on their food to liquefy it, making it easier for them to digest.
Over 100 pathogens are associated with the common house fly including: E. coli, Salmonella, Staphylococcus and Shigella. These pathogens can cause disease in humans, including cholera, hepatitis, typhoid fever, bacillary dysentery, polio, tuberculosis, ophthalmia and infantile diarrhea.
Commercial Fly Hazards
The sanitation problems that a fly can cause should concern all proprietors of establishments that serve food. A single fly can cause an illness outbreak at a restaurant, the shutdown of a hospital operating room, as well as the complete shutdown of a food processing plant. Therefore, preventative measures are the most efficient and effective way to control this problem. It should be a law to control flying insects and you owe it to your customers and yourselves to ensure flies are not spreading disease on the premises.
Every year, newer, stronger chemical pesticides are developed to help control the fly population. The primary reason for new insecticides each year is “resistance” to the products on the market. Resistance is the ability of an insect population to withstand exposure to insecticides. This is acquired by breeding from insects that have survived previous exposures to a pesticide that did not wipe out the whole population. The surviving insect breed and develop a resistant strain that survives insecticide treatment.
