HOUSE FLIES

Buzzing around yards, trash bins, and kitchens, house flies are more than just an annoyance—they’re potential disease carriers. Originally from central Asia, these resilient insects have followed humans across the globe, thriving around people and animals. Their preference for breeding in feces and garbage makes them effective transmitters of harmful pathogens, which they can spread to food and food preparation surfaces. In fact, studies show that controlling house fly populations in communities can significantly reduce cases of infectious diarrhea. Understanding the habits and risks associated with house flies is the first step toward effective management.

House flies rarely breed indoors unless conditions are extremely unsanitary, or if garbage dumpsters or compactors are kept inside buildings. They’re a more significant issue in areas with animal farming due to the abundance of manure. In urban settings, house flies are primarily attracted to strong odors from outdoor garbage dumpsters and bins. To minimize this attraction, it’s essential to clean garbage containers regularly and keep their lids tightly closed. Additionally, keeping garbage far from building entrances helps prevent flies from finding their way indoors. Ultimately, maintaining clean surroundings and ensuring that windows and doors are either closed or properly screened are the most effective methods for keeping house flies outside where they belong.

While maintaining cleanliness and securing entry points are essential first steps, using targeted fly control products can further enhance your efforts. Hang Catchmaster Baited Fly Bag traps 30 feet away from outdoor living and eating areas to help keep them fly free. The Gardner FlyWeb Classic insect light trap (ILT) is effective at catching house flies once inside. Correct placement is important, as house flies are most active within three to six feet above the floor, and ILTs placed higher are less effective. PT Alpine Pressurized Fly Bait can be used in addition to ILTs. It works quickly and is convenient to apply, especially as removable bait placements in food-handling areas.

By understanding the habits of house flies and taking proactive measures—ranging from sanitation practices to strategic product use—you can effectively minimize their presence and reduce health risks. Implementing these strategies not only protects food safety but also enhances the comfort and cleanliness of living and working environments.
