DIY Mosquito Trap with a Water Bottle: Simple Steps to Effective Mosquito Control

Mosquitoes can quickly turn outdoor activities into a frustrating experience. Creating your own mosquito trap using a water bottle can be an inexpensive and efficient way to combat these bothersome insects. In this article, we will guide you through the process of making a DIY mosquito trap using a water bottle, helping you reclaim your outdoor spaces and enjoy mosquito-free moments.

Materials You’ll Need

To create a mosquito trap with a water bottle, gather the following materials:

  1. Empty plastic water bottle (1 or 2-liter)
  2. Sharp knife or scissors
  3. Sugar
  4. Active dry yeast
  5. Measuring spoons
  6. Warm water
  7. Black paper or tape
  8. String or wire
  9. Optional: Masking tape or adhesive

Step 1: Prepare the Bottle
Start by removing any labels or stickers from the plastic water bottle. Use a sharp knife or scissors to carefully cut off the top third of the bottle. Ensure that the cut is just below the point where the bottle begins to narrow.

Step 2: Create the Funnel
Invert the top portion of the bottle (with the cap removed) and insert it into the bottom portion of the bottle, creating a funnel-like shape. Make sure the opening of the funnel is facing downwards.

Step 3: Prepare the Bait
In a separate container, mix 1 tablespoon of sugar with 1 cup of warm water. Stir the mixture until the sugar completely dissolves. Let the mixture cool to room temperature.

Step 4: Activate the Yeast
In a small bowl, combine 1 teaspoon of active dry yeast with 1 tablespoon of sugar. Add ¼ cup of lukewarm water to the mixture and gently stir. Allow the yeast to activate for about 10 minutes.

Step 5: Assemble the Trap
Pour the cooled sugar water into the bottom part of the bottle, filling it up to about one-third of its capacity. Add the yeast mixture to the sugar water and gently stir. The yeast will produce carbon dioxide, which attracts mosquitoes.

Step 6: Enhance the Trap
Wrap the upper portion of the bottle, excluding the funnel, with black paper or tape. Mosquitoes are naturally attracted to dark objects, making the trap more appealing to them. Use string or wire to secure the paper or tape in place.

Step 7: Position the Trap
Place the mosquito trap in areas where mosquitoes are likely to congregate, such as near sitting areas, gardens, or entrances. Hang the trap or position it upright using string or wire.

Step 8: Monitor and Maintain
Regularly check the trap and empty the contents as needed. Refill the trap with a fresh sugar water and yeast mixture every two weeks or as necessary.


By following these simple steps, you can create an effective mosquito trap using a water bottle and common household materials. This DIY solution takes advantage of carbon dioxide attraction to lure and trap mosquitoes. Place the trap strategically, maintain it regularly, and enjoy mosquito-free outdoor spaces. Take control of mosquito problems and enhance your outdoor experience with this homemade mosquito trap.
