Here are solutions for flies being attracted to white cars: 1. The best way is to park the car away from places where flies tend to gather, such as under trees, near water, or garbage dumps. 2. Wash the car frequently, or always keep a few bottles of water and soft cleaning cloths in the car to wipe off any fly droppings immediately. 3. Another straightforward solution is to repaint the entire car, changing it from white to green, giving it a fresh new look. Additional information: 1. Flies are not particularly sensitive to colors, and there is a theory that their compound eyes cannot distinguish colors. Therefore, flies are unlikely to choose white cars because they like the color white. Compound eyes are very sensitive to light and flickering, so the most probable reason flies are attracted to white cars is the reflection of light off the white surface. In general, warm-colored vehicles attract more flies than cool-colored ones. 2. Additionally, white cars are just as likely to get dirty as cars of other colors, but the dirt is more visible to the naked eye. Champagne, green, and silver are widely recognized in the industry as easier to maintain. If the car is parked near a food stall, commercial building, or behind a hotel kitchen, especially when the air is humid, not washing the car for a few days will result in a mixture of oil smoke and dust turning into small black spots that firmly adhere to the car's surface. Regular car washing may not completely remove these black spots; you can try using a tar remover and then apply wax to form a protective layer.
