Indoor fly control can be a challenge. Whether you’re after the best indoor fly killer or an eco-friendly trap, knowing what truly works—and why—is key.
This guide covers six must-know tips to help you choose the best fly traps for indoors that are effective, safe, sustainable and stylish.
As Susan, a satisfied user of The Fly Inn Flying Insect Trap, aptly puts it, "They work! They catch so many flies."
1. Why color affects fly attraction
Understanding what draws flies to traps is key—and at the heart of this strategy is color. Certain shades, especially blue, act like magnets for flies. Research led by experts like Dr. Roger Santer reveals a strong attraction flies have to the color blue, often linking it to potential meals. This insight shaped the design of The Fly Inn, which harnesses blue's allure to boost trap effectiveness.

But this attraction goes deeper than color alone. Flies are particularly drawn to blue light due to its intensity, which likely stimulates more of their visual receptors than other hues. Studies suggest flies see blue as a cool, shaded refuge—especially appealing in warmer conditions. Black lines or patterns on blue traps boost appeal by mimicking natural shelters like cracks or crevices.
Our lab studies show that flies are 78.91% more likely to be lured by specific shades of blue, making this color a powerful tool for effective fly control.
2. Why mechanical fly traps are the best indoor fly control solution
When it comes to indoor pests, your method matters. Mechanical methods—like The Fly Inn—use clever designs and sticky surfaces to catch flies effectively. Mechanical fly traps—sometimes referred to as mechanical fly control devices—work without chemicals, using only physical mechanisms like glue boards or trap-and-hide systems.
Here are four reasons why opting for mechanical control is a smart choice.
- Eco-friendly fly control solution: Mechanical traps avoid toxic chemicals, keeping your home safe from invisible health threats.
- Sustainable: Unlike chemical methods, which pests can grow resistant to, mechanical traps offer a consistent, long-term solution. Physical traps don't allow resistance to develop.
- Safe: These traps eliminate the need for harmful substances, protecting your family, pets, local wildlife and the environment.
- Peace of mind: No residues or toxic effects—just a cleaner, safer home.
3. Simple and effective indoor fly control solutions

A top-notch indoor fly control solution should be easy to use and highly effective.

4. Eco-friendly fly control solution for your home
When it comes to indoor fly control, safety should be a top priority. Skip chemical-based products and choose all-natural solutions that effectively manage flies without compromising your home’s air quality or your family’s well-being. Look for options that are safe for children, pets and the environment.
