House flies of any kind are more than just a nuisance. These disease-carrying pests can transfer germs and bacteria to your household surfaces. Tiny black flies in the home, such as fruit flies or little house flies, are active in the home while laying eggs or searching for food sources. Preventive measures are best to keeping these flies and their eggs out of the house in the first place. Once their presence has been made, proper cleaning and insect control measures get rid of the little house flies and fruit flies.
Discard overly ripe or bruised produce stored on your counter or table top. Throw these foods in a trash bag and place fruits and vegetables that aren't too ripe in the refrigerator where tiny fruit flies can't get to them.
Mix all-purpose disinfectant cleaner in a bucket with 1 gallon of hot water. Wash kitchen and bathroom surfaces, as well as floors throughout your home. Pour some of the disinfectant solution down sink and garbage disposal drains to clean out the drains and get rid of any eggs laid by little house flies.
Trap little flies buzzing around your home by luring them with vinegar. Pour a few inches of cider vinegar in the bottom of a glass jar. Cover the mouth of the jar with cling film and secure it around the jar with tape. Use a fork to poke several holes in the cling film.
Set the jar in an area close to fly infestations. The flies will go into the jar to get the vinegar, then become trapped. Flush them down the toilet the next day and replenish the vinegar jar trap.
Kill flies in other areas of the house with fly paper. Hang the paper where flies are seen flying around your home.
Flying insect spray can be used to kill flies but use caution since commercial sprays contain toxic chemicals. Keep fly swatters handy to kill flies on sight. Check window and door screens for tears or holes. Use a screen repair kit to patch the screens and prevent flies from entering the home.
