Bananas are the ultimate grab-and-go snack\u2014loved year-round. But once temperatures climb in May, your kitchen can turn into a fruit-fly playground in just a few days if you don\u2019t change up how you store them.<\/p>\n

The sweet aroma of bananas is irresistible to fruit flies, and because these pests reproduce so rapidly, a small problem can become a full-blown infestation fast.<\/p>\n

Banana stems emit concentrated ethylene gas, which accelerates ripening.<\/p>\n

At room temperature, banana sugars can start to ferment and produce a tangy scent that fruit flies can detect from up to 1\u339e (about 0.62 miles) away. These tiny pests measure just 2\u20135\u339c (0.08\u20130.20 in), small enough to slip through window screens or drain gaps and get inside.<\/p>\n

Yang Young-chul, who appeared on Korean broadcaster YTN in 2021, said a single female can lay roughly 100 eggs at once. With only about 10 days from egg to adult, populations can explode. If you spot one or two fruit flies indoors, hundreds of unseen eggs may already be hiding nearby.<\/p>\n

Here\u2019s how to keep bananas fresh longer\u2014and fruit-fly free.<\/p>\n

\u25a0 Wash them the same day to prevent fruit flies<\/strong>\n<\/div>\n

On the day you buy them, rinse banana peels under running water at least three times, or rinse with a vinegar-and-water mix (1:10 vinegar to water) to remove surface sugars and residue.<\/p>\n

After washing, pat them completely dry with a paper towel to prevent mold. Then trim off the top and bottom stems to reduce ethylene release and eliminate hiding spots for fruit flies.<\/p>\n

If cutting the stems feels awkward, wrap them tightly in aluminum foil or plastic wrap instead. Bananas with their stems wrapped can stay fresh about 3\u20135 days longer than untreated ones.<\/p>\n

\u25a0 Store them separated and off the surface<\/strong>\n<\/div>\n

Leaving bananas in a bunch lets them exchange ethylene gas, which can speed browning by up to about 1.5 times.<\/p>\n

Peel them off and seal each banana in a zip-top or plastic bag to block odors and slow ripening.<\/p>\n

Where you store them matters. If you leave bananas lying on a counter, the spots where they touch will brown first, creating openings fruit flies can exploit.<\/p>\n

Use a banana hanger, or if you don\u2019t have one, hang bananas by the stems on a clothes hanger so they don\u2019t touch surfaces.<\/p>\n

Overripe bananas with blackened peels attract even more fruit flies if left out.<\/p>\n

Peel and freeze overly ripe bananas to remove the attractant; they\u2019ll keep for 2 to 3 months and are perfect for smoothies or pancake batter.<\/p>\n

\u25a0 How to make a fruit fly trap<\/strong>\n<\/div>\n

If fruit flies have multiplied in your home, cut a plastic bottle in half, invert the top to create a funnel, and add a mix of vinegar and sugar (1:1) with a little dish soap in the bottom half.<\/p>\n

Drawn by the tangy-sweet scent, flies crawl in and the dish soap breaks the surface tension so they can\u2019t escape.<\/p>\n

Pour baking soda and vinegar down drains and clean them once or twice a week to help remove eggs and larvae.<\/p>\n
