Simple Secret to Stop Fruit Flies

 A Bug Expert Reveals the Simple Secret to Stop Fruit Flies

One entomologist spilled the beans on how to keep those little pests
out of your hair. Here's the best way to keep your kitchen bug-free.

Beer, wine and soda are like a siren song for fruit flies.

Fruit flies will normally hitch onto any overripe fruit that you bring
home from the grocery store, or any bruised fruit, which tends to
ripen and rot more quickly.

Once the flies get in your house, she said, they'll lay eggs
everywhere they can --- in rotten fruit or any fermented substances,
especially onions and potatoes. And as it gets warmer, their life
cycles quicken. That's how infestations happen.

Once fruit flies descend on your kitchen, it's tough to get them to
leave.

The common name that entomologists give fruit flies is "vinegar
flies." That's because they're naturally attracted to fermented
liquid, and when fruit rots, it also ferments.

But fruit flies don't thrive only on rotten fruit or vinegar. They
also love sugary substances like soda, wine and beer, and you can find
them in the bottom of your trash bin or any wet place with a
substantial food source.

"Substantial food source" may mean something different to you than to
the small but mighty fruit fly, Green said. "It may not be the food
you are wanting to eat, but fruit flies are so tiny it only takes a
tiny microhabitat" -- like the residual soda in a can in your
recycling bin or leftover bits and crumbs in a takeout container in
your garbage, Green explained. Those are prime spots for fruit flies
to breed. Once the weather warms, it takes less time for fruit fly
eggs to turn into babies.
