Light-based fly repellents may refract light and disturb the optical perception of houseflies. Light may be refracted and the optical perception of houseflies may be disturbed through use of a clear or lightly color-tinted liquid enclosed in a sealed clear or lightly color-tinted body housed in a frame. When natural light (such as sunlight) or light available from other sources (such as a lamp or porch light) is placed in contact with the repellent, houseflies may be influenced not to aggregate around the area where the repellent may be positioned.
