The house fly has a gray thorax with 4 dark, longitudinal stripes.There are so many devices to kill the flies.
Flyswatter usually consists of a small rectangular or round sheet (some 4 inches (10 cm) across) of lightweight, flexible, vented material (usually thin metallic, rubber, or plastic mesh), attached to a lightweight wire or plastic handle about 1 foot (0.30 m) to 2 feet (0.61 m) long.Fly gun a derivative of the flyswatter, uses a spring-loaded plastic projectile to mechanically “swat” flies.
Mostly flies develop in garbage, manure, compost piles or other animal materials while some flies such as fruit flies or drain flies can also breed inside the house. They feed mostly on liquid foods. During feeding, flies also defecate on the food. As a result flies are commonly known for transmitting severe health risks by spreading disease organisms.
The presence of flies will indicate unhygienic conditions and will disturb the work of humans. They carry disease-causing organisms in their legs, so they can spread diseases to people by contact with food. They transmit diseases like diarrhea, typhoid, cholera, and some other diseases.
