GUIDE DESCRIPTION

Flies are more than just an annoyance—they can spread bacteria and make your home feel unhygienic. Windows are one of the most common entry points for flies, especially during warm weather when they’re left open for ventilation. Fortunately, there are simple, effective, and natural methods to keep flies from entering through windows.

The most effective barrier is installing window screens. Fine-mesh screens allow fresh air to flow in while blocking flies and other insects. If you already have screens, check for small tears or holes and repair them to ensure full protection.

Next, focus on sealing cracks and gaps. Even small openings around window frames provide entry points for flies. Applying weatherstripping or caulking prevents flies—and improves energy efficiency at the same time.

Natural repellents can be a powerful addition. Essential oils like eucalyptus, lavender, peppermint, or lemongrass can be applied to cotton balls and placed on windowsills. These scents repel flies naturally without harsh chemicals.

Keeping windows and surrounding areas clean is another key factor. Food crumbs, sugary spills, or sticky residue can draw flies closer. Regularly wiping frames and sills ensures your windows aren’t attracting pests in the first place.

You can also decorate with fly-repelling plants such as basil, mint, or marigolds in pots near windows. These plants not only add beauty but also give off scents that flies dislike.

Finally, for added control, consider DIY window fly traps. A small bowl of apple cider vinegar with a drop of dish soap placed near a window will attract and trap flies. Positioning traps away from seating areas ensures flies are lured elsewhere.

By combining barriers, repellents, cleanliness, and traps, you can keep flies out of your home while still enjoying open windows and fresh air.
