While everyone has had fly problems at some point, it is very important to take care of them quickly as flies can easily transmit pathogens and bacteria to food and people. They will breed in places like rotten food, manure, and garbage so when they travel to other things like people or the food the people are eating it can transfer the bacteria easily. They can also mature from an egg to an adult in as little as ten days so fly problems can escalate quickly.
The best ways for people to prevent and keep and fly problems to a minimum are to keep their houses and living areas clean. Flies are attracted to the waste that people leave behind so it is very important to take the trash out and get rid of any exposed food so the flies cannot feast on it.
