Flies are a normal presence outdoors, but when a sudden fly invasion occurs in your home, garage or on your deck it's indicative of flies breeding and living somewhere close by. To effectively get rid of fly infestations, you must remove potential breeding grounds and kill both young and mature flies. Simply killing flies is not enough to keep the invasion from returning. Long-lasting control and removal depends upon clean surroundings that don't encourage flies to linger.
Place bags of manure or compost stored in your garage or outdoors into plastic bins with lids. This ensures flies can't lay eggs in the mixtures.
Vacuum inside your home and sweep the deck, patio and any other outdoor living areas to remove crumbs and anything else that might attract flies. Wash surfaces with liquid pine cleaner mixed in a gallon of water to clean up juice or beverage spills that draw flies. Repeat this step, as needed, to maintain clean living areas that don't encourage the presence of flies.
Store produce in the refrigerator rather than on the counter top where it will spoil faster and draw flies.
Hang fly paper in areas affected by the fly invasion. Change the fly paper on a weekly basis as flies are caught and trapped in the sticky adhesive.
Boil water in a large cooking pot and pour the boiling water over garbage in dustbins, compost or manure piles or anywhere else where maggots have been spotted. Maggots look like small, white worms and are flies in the larvae stage. Pouring boiling water over them will kill them and interrupt the life cycle.
Store trash in cans with lids to prevent adult flies from laying eggs in your garbage.
Keep a fly swatter handy to kill flies as you see them. After removing the dead fly, wash the area with the pine liquid solution to remove germs and disease.
Check screen-covered windows and doors to ensure there are no holes that allow flies to come through. Use flying insect insecticides to kill flies in areas where pets and young children aren't present.
