It's amazing how quickly a fruit fly infestation can get out of hand. You may notice one fly buzzing around your fruit in the morning, then come home from work to see half a dozen more. It's not your imagination; those flies are multiplying—and fast! Fruit fly larvae hatch just 24 hours after eggs are laid, so you'll want to act fast to take them out. Cut off their food supply by storing soft fruits in the refrigerator. Also, immediately wipe down cutting boards and counters after food prep, and empty your garbage and recycling cans daily. If, in spite of these preventive measures, you spot a few fruit flies, create a simple DIY trap by filling a small tumbler halfway with apple cider vinegar. Then, add a tablespoon of dishwashing liquid, and fill the glass the rest of the way with warm water. The flies will fly into the tumbler, but they won't fly out.
