How to Make a Fruit Fly Trap at Home

DIY fruit fly traps are cheap, easy, and genuinely effective. Here are the best homemade options — plus tips to make them work faster.

Why DIY Traps Work

Fruit flies are attracted to fermentation and sweet smells. A good trap exploits this by luring them in with an attractive bait and then preventing escape. The key is the right bait + the right container design.

Trap 1: The Classic Jar Trap

What you need: A small jar or glass, plastic wrap, a rubber band, a toothpick

Bait options (pick one):

A few tablespoons of red wine
Overripe fruit pieces
A splash of fruit juice with a drop of dish soap

How to make it:

Add your bait to the jar
Cover tightly with plastic wrap
Secure with a rubber band
Poke 8–10 small holes with a toothpick

Flies enter through the holes but can't find their way back out. Empty and reset every 2–3 days.

Trap 2: The Funnel Trap

What you need: A jar, a piece of paper, tape, bait

Roll the paper into a cone/funnel shape and tape it so it holds. Place the narrow end into the jar (don't let it touch the bait). Flies fly down the funnel toward the bait and can't navigate back up.

Trap 3: The Dish Soap Bowl

What you need: A shallow bowl, water, dish soap, a splash of wine or juice

Mix together and leave near the fruit bowl or sink. The soap breaks surface tension — flies land and sink. Simple and effective for quick knockdown.

Trap 4: The Bottle Trap

Use an almost-empty bottle of wine, beer, or juice. Leave it on the counter. The narrow neck traps flies inside. Replace every few days.

Tips to Make DIY Traps More Effective

Place traps near where you see the most flies (fruit bowl, sink, trash area)
Use multiple traps in different spots
Change bait every 2–3 days — fresh bait attracts more flies
Run traps alongside a plug-in device like the Zevo Flying Insect Trap for 24/7 coverage without daily maintenance

What Won't Work

Traps alone won't eliminate an infestation if the breeding source remains
Bait that's too old loses its attractiveness
Traps placed too far from the source catch fewer flies

The Bottom Line

DIY traps are a great first response and cost nothing. For faster results, combine them with drain cleaning and a sealed trash can — and you'll break the cycle much sooner.
