🦟 “1 Magic Trick” to Get Rid of Mosquitoes for Good: The Sugar-Yeast Mosquito Trap
This simple, chemical-free trick attracts and traps mosquitoes using carbon dioxide (CO₂)—which is what mosquitoes are naturally drawn to when they hunt for humans.
✅ How it works:
When you mix sugar, warm water, and yeast, the yeast feeds on the sugar and produces carbon dioxide gas—just like humans do when we exhale. Mosquitoes detect CO₂ and fly toward it, thinking there’s a person nearby. Instead, they get trapped and can’t escape.
🧪 What you need:
- 1 empty plastic bottle (1.5L or 2L)
- 1/4 cup brown sugar (white sugar also works)
- 1 cup warm water
- 1 teaspoon dry yeast (instant yeast)
- Scissors or a knife
- Tape or staples
- Optional: black paper or cloth to wrap the bottle (mosquitoes are attracted to dark colors)
🛠️ How to make it:
- Cut the bottle:
- Cut the plastic bottle in half.
- Keep both the bottom and top parts.
- Make the mixture:
- Pour warm water into the bottom half of the bottle.
- Add the sugar and stir until dissolved.
- Sprinkle the yeast on top. Do not stir—the yeast will activate slowly.
- Assemble the trap:
- Take the top half of the bottle (with the neck) and invert it like a funnel.
- Place it inside the bottom half, neck-down (but not touching the liquid).
- Seal the edges with tape or staples to make sure mosquitoes can’t escape.
- Cover with something dark (optional but increases effectiveness).
- Wrap the bottle in dark paper or cloth, leaving the top open.
- Place in a mosquito-prone area:
- Set the trap in a dark, quiet corner (indoors or outdoors).
- Avoid placing it next to fans or wind.
⏱️ How long does it last?
- The solution will produce CO₂ for about 1–2 weeks.
- Replace the mixture every 10–14 days for best results.
🧠 Why it’s effective:
- Chemical-free and safe around pets/kids.
- Very cheap and easy to make.
- Lures mosquitoes 24/7 using natural human-like cues (CO₂ and warmth).
⚠️ Bonus Tips:
- Use multiple traps for larger areas.
- Place near windows, doors, or under tables.
- Don’t forget to eliminate standing water nearby (where mosquitoes lay eggs).
