Fruit Flies and Homegrown Sprouts

People often ask how they can stop those pesky fruit flies that fly around their sprouts. Here's a few tips to get rid of them.

About Fruit Flies
  • The common fruit fly, Drosophila melanogaster, is a small fly about 1/10th of an inch long. The overall color is brown or tan, with red or black eyes.
  • It’s easy to confuse fruit flies and gnats, however gnats live outdoors, not inside the home.
  • Fruit flies come inside our homes inside fruits and veggies. The female fruit fly lays her eggs inside fruit, when the eggs hatch, the flies emerge in our kitchens. 
  • These flies do not arrive with seeds for sprouting or on sprouted seeds.
  • Fruit flies like the warm, moist environment of sprouts and wheatgrass and fly around them. 
  • These insects occur  most frequently in the warmer summer months. 
  • By following a few easy steps, you can eliminate fruit flies in your home.

How to Prevent fruit flies

  • Wash the fruits and vegetables you bring home.

  • Store fruits and vegetables in the fridge so the fruit fly eggs cannot hatch.

  • Lower the temperature of your sprouts, fruit flies like warmer temperatures. It’s a good idea to put your sprouts in the fridge for a few hours a day.
  • Point a fan directly at your sprouts. Fruit flies don’t like the air circulation or the cooler temperatures a fan brings.

  • Store your mature sprouts in the fridge, keeping the temperature cool will keep the fruit flies away. Rinse and drain your sprouts once a day to keep them hydrated.
