These DIY traps work by luring and catching flies. They keep your home and outdoor areas healthy and free from flies.

Materials Needed for a DIY Fly Trap

ou don’t need fancy tools or a trip to the store—just grab what’s already lying around the house. The beauty of this project is how simple (and cheap) it is to pull off.

Plastic Bottle
Any clear plastic bottle will do—a soda or water bottle is perfect. You’ll cut and flip it to make the fly funnel.

Water + Dish Soap
Add water and a squirt of dish soap to your trap. The soap breaks the surface tension so the flies sink instead of escaping.

Bait
This is where the magic happens. Flies love anything smelly and sweet. Think sugar water, overripe fruit, raw meat, or even pet waste if you’re outdoors. The riper, the better—fermentation makes it more irresistible.

Step-by-Step Guide to Making a DIY Fly Trap

Making your own fly trap takes just a few minutes—and the payoff is huge. Here’s how to build one that works, using stuff you already have on hand.

1. Prep the Bottle
Grab a clean plastic bottle (a soda or water bottle works great). Cut it in half with scissors or a sharp knife. You’ll use the bottom half for the bait and flip the top half upside down to create a funnel that guides flies in—but makes it hard for them to escape.

2. Mix the Bait
In the bottom half of the bottle, pour in your chosen bait. A simple mix of sugar water works, or level up with apple cider vinegar and overripe fruit. Want it stronger? Add a splash of dish soap. That breaks surface tension and helps trap the flies once they land.

3. Assemble the Trap
Insert the top half of the bottle upside down into the bottom, funnel-style. You should now have a simple trap with a narrow opening that draws flies in but keeps them from flying back out.

4. Set It Up
Place your trap in a sunny spot near fly-prone areas like trash cans, compost bins, or pet feeding stations. Let it sit for a few days, then check the results.
