There are many different ways a fly in can enter a home. The insects can enter houses on food products (fruit flies) or drift in through open windows and doors. They may also be attracted to and develop in decaying organic matter in drains. From house flies to fruit flies, the key to fly control is sanitation. Be sure to clean any spilled liquids, especially fruit juices, in order to cut down on fly activity. Regularly removing garbage from the area, as well as cleaning drains will also help lessen a fly infestation. Flies are attracted to lights, especially at night.
