How to Eradicate Fruit Flies Indoors
- 1). Locate the breeding source and remove it. This may be a batch of bananas on the counter, or an old cucumber in your trash can. Bag up the old fruits and vegetables and toss them in an outdoor trash can.
- 2). Wipe down the entire area with a 1:4 bleach/water solution. Use the solution in drains, and to wipe down your trash can. Run your dishwasher through one cycle without placing any new dishes in it. The key is to remove any traces of food from your kitchen that can possibly attract the remaining fruit flies.
- 3). Set up a fruit fly trap to catch the living adults that are still in your house. Place 2 oz. of apple cider vinegar in a glass jar. Create a funnel out of a piece of paper and set it in the jar's opening. The adults will fly in because they're attracted to the vinegar, but they won't be able to fly back out.
- 4). Spray any adult fruit flies that weren't fooled by the trap with a pyrethrum-based insecticide. Pyrethrum is safe for indoor use because it comes from dried up chrysanthemum plants.
