GE Fly Repellent solution is entirely made from plant based extracts. Once the G045 fly repellent is sprayed the flies are disoriented and deterred from entering the space again. It makes your house a formidable fortress against flies. G045 is used for multiple applications. For example, it can be used for floor mopping, garbage room, lockers and receiving areas. It is also a deodorizer and a sanitizer as well.
