Homemade Fruit Fly Traps: Do They Work?

Many kitchens have a bowl of vinegar set out to catch fruit flies. Do these traps actually work?

The short answer

Homemade traps using apple cider vinegar or ripe fruit with a drop of dish soap and a funnel or cling film can catch some adult fruit flies. They reduce numbers but do not remove the breeding source. Combine traps with removing ripe produce, cleaning bins and drains and wiping spills. If flies persist after sanitation, there may be a hidden source needing professional help.

How to make one

1. Pour vinegar or a bit of ripe fruit juice into a jar.
2. Add a drop of dish soap to break surface tension.
3. Cover with cling film with small holes, or use a paper cone.
4. Place near the problem area and replace every few days.

What traps do

• Catch adult flies.
• Show whether flies are present.
• Help reduce numbers.

What they don't do

• Stop breeding.
• Remove larvae in drains.
• Replace cleaning.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
