  • How to keep pesky flies away from your BBQ

    Here's the reason behind the effectiveness of homemade repellents. Flies have visual receptors called ommatidia. Unlike humans, they don't have pupils that controls the amount of light that enters their eyes. Our pupils do, their ommatidium do not. Therefore, the reflective light or flickering light "scares" them because they can't focus. Another homemade repellent is the use of an old CD. Just hang one nearby and allow our wonderful sun do its magic! The spinning CD that reflects the sunlight is a knockout for those pesky flies!!! Trust me...it works.
