Natural fly traps are a type of insect trap that uses natural materials to attract and capture flies. They are an environmentally friendly alternative to chemical insecticides, as they do not contain any harmful chemicals. The most common type of natural fly trap is a web, which is made from a sticky material such as cotton or silk. The web is placed in areas where flies are likely to be found, such as near garbage cans or near food sources. Once the flies land on the web, they become stuck and can no longer escape. Natural fly traps are an effective way to reduce the number of flies in an area without the use of chemicals.
