Fly traps are an essential device to keep flying insects away from outdoor and indoor living spaces. However, there are several synonyms you can use to refer to them. One popular alternative term is a fly catcher, which is an adhesive material capable of trapping insects. Another synonymous term is a flypaper, which is a sticky surface coated with an attractant that captures flying insects. In addition, a bug zapper emits UV rays that attract the insects and electrocute them when they make contact with the device. Lastly, a fly swatter is a manual tool you can use to physically swat flying insects and eliminate them. All these synonyms serve the same purpose of keeping your home or outdoor space free of unwanted pests.
