While they are only able to feed on liquids, house flies 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. House flies tend to stay within 1-2 miles of where they were born; however, they have been known to migrate up to 20 miles to find food.
These pesky insects have been known to carry over 100 different kinds of disease-causing germs, which makes them very bad house guests. House flies can be controlled through vigilant sanitation. Remove trash regularly and use well-sealing garbage receptacles. Clean up pet waste immediately. Use fine mesh screens on doors and windows to prevent fly entry.
