The two most common flies we encounter are the House Fly and the Fruit Fly:
House flies – get their name from being the most common fly found around homes. Adult house flies can grow to one-quarter of an inch long and usually live between 15 and 25 days. They are only able to feed on liquids but have the ability to turn many solid foods into a liquid for them to eat. House flies taste with their feet, which are 10 million times more sensitive to sugar than the human tongue.
These insects have been known to carry over 100 different kinds of disease-causing germs, which make them very bad house guests.
Fruit Flies – Fruit flies feed on decaying matter, especially fruits and vegetables. Fruit flies are small pests that are commonly found in homes, restaurants and other facilities where food is processed. They are found on moist, decaying matter that has been stationary for several days.
Fruit flies are found in unsanitary conditions, so they are a potential heath concern, especially when present in health facilities.
