Flies are attracted to a variety of things, primarily sources of food and breeding grounds, which often involve decaying organic matter.
Common Attractants for Flies
Here's a breakdown of what typically lures flies:
-
Uncovered Garbage Cans: Flies are drawn to the smells emanating from decomposing waste. The contents offer a food source and a place to lay eggs.
-
Animal Carcasses: The decaying flesh of dead animals (whether inside walls, attics, or elsewhere) provides a significant attractant for flies, offering both sustenance and a breeding site.
-
Manure and Pet Feces: Animal waste is a rich source of organic material for flies, serving as both a food source for adults and a larval development medium.
-
Fermenting Fruit: Overripe or decaying fruit releases sugary aromas that attract fruit flies. These flies thrive on the sugars produced during fermentation.
-
Spilled Soda and Open Alcohol Containers: The sweet and alcoholic content of these liquids are extremely attractive to various fly species.
-
Drain Scum: The buildup of organic matter and moisture in drains creates an ideal breeding ground for drain flies.
Why These Things Attract Flies
Flies have a highly developed sense of smell, allowing them to detect volatile organic compounds (VOCs) released by decaying matter, fermentation, and other processes. These odors act as signals, indicating a potential food source or breeding site. Flies also possess specialized sensory organs that can detect sweetness and other appealing characteristics.
Controlling Fly Attractants
To minimize fly infestations, it is crucial to:
- Keep garbage cans tightly sealed.
- Promptly remove animal waste from yards.
- Clean up spills immediately.
- Regularly clean drains.
- Avoid leaving fruit out on countertops for extended periods.
- Address any potential animal carcass issues inside buildings.
By eliminating or minimizing these attractants, you can significantly reduce the number of flies around your home or business.
