Dealing with a fly infestation at home? This season's invasion can be overwhelming, but you can combat it effectively with a simple homemade fly trap made from a plastic bottle.
As a seasoned DIY pest control expert, I've tested countless natural solutions, and this one stands out for its simplicity, affordability, and proven results—without harsh chemicals.
Follow this quick tutorial to create your trap in under a minute:


1. Cut off the top third of the bottle with a knife. No need for a perfect cut—it's still highly effective!
2. Invert the top to form a funnel and insert it into the bottom. Secure with tape if desired.

3. Add a few centimeters of water to the base, ensuring space below the funnel.
4. Add your chosen bait (see below).
5. Mix in 1-2 drops of dish soap.

Your homemade trap rivals commercial ones at a fraction of the cost. Perfect for indoor or outdoor use—no more buzzing pests!
Flies are drawn to sweet, fermenting scents. Top options include:
Let the bait ferment slightly for better results. Place the trap where flies congregate.

Flies enter via the funnel, attracted by the bait. They can't escape the slick surface, fall into the soapy water, and drown. The soap reduces surface tension, ensuring they sink fast.
