Mosquitoes can be really annoying, especially if you’re outside in the evening. Try making a bucket trap, a sweet water trap, or a fan trap to catch pesky mosquitoes and keep them from biting you. These traps are quick and easy to make and require simple materials. Simply place the trap in an area that has lots of mosquitoes and wait for them to find it.

Making a Bucket Trap

  1. Choose an old bucket and use a hose to fill it with water. If the bucket is very large, only fill it a quarter of the way, as you will need to be able to move the bucket. [1]
    • If you don’t have a bucket at home, recycle an old plastic container instead.
  2. Mosquitoes are attracted to stagnant water, as this is where they lay their eggs. The detergent will remove the surface tension of the water and cause the mosquitoes to drown when they land on the water. [2] Gently squeeze the drops into the middle of the bucket. [3]
    • Any liquid washing detergent, such as dish soap, will work for this trap.

  3. Avoid stirring the water vigorously, as this can cause lots of bubbles in the water. Stir the mixture for about 10 seconds, or until the detergent is distributed across the top of the water. [4]
    • Your mosquito trap is now ready to catch pesky mosquitoes.
  4. If you find that your trap is not catching many mosquitoes, move it to a well-lit area, such as under an outside light. This helps to attract the mosquitoes to the water. [5]
    • If you don’t have an outside light, set up a solar light next to the trap. Avoid using electricity near the trap, as this can be dangerous.

Trapping Mosquitoes with Sweet Water

  1. Use a sharp pair of scissors to cut around the bottle, just above the label or where the bottle starts to curve toward the lid. Keep the spout, as you will need to use this later. [6]
    • If you’re having trouble cutting the bottle with scissors, use a craft knife instead.
  2. Measure the sugar and hot water into the bottle. Stir the mixture with a spoon until the ingredients are thoroughly combined. [7]
    • Run the kitchen tap until the water is hot. Don’t use boiling water, as this can damage the yeast.
    • Both white sugar and raw sugar will work for this trap.
  3. Measure the yeast into the sugar and water solution. Use a spoon to stir the mixture until it is frothy. This normally takes about 30 seconds. The yeast feeds off the sugar and releases carbon dioxide which attracts mosquitoes. [8]
    • Purchase active dry yeast from the baking section of a grocery store.
  4. Measure tap water into the mosquito trap. Stir the mixture until the ingredients are thoroughly combined. [9]
    • If your tap water is hot, leave the water to cool at room temperature for 15 minutes.
  5. This gives time for the yeast to ferment. Place plastic wrap over the container but don’t secure it in place, as the mixture needs to be able to breathe. Store the bottle in a warm, dry, and humid place. [10]
    • A hot water heater closet and a loft are ideal storage locations
  6. This confuses the mosquitoes and causes them to get trapped in the bottle. Take the sprout that you cut off the bottle and insert it into the bottle upside down. Line the cut edges of the bottle up so that they are at the same height. [11]
    • Leave the bottle lid off the spout.
  7. Use heavy-duty tape (like duct tape) to connect both pieces of the bottle. Cover the entire rim to ensure that the spout and bottle are securely joined. [12]
    • Heavy-duty tape works well for this trap.
  8. Mosquitoes are often attracted to light and water. Consider placing the trap beside a pool or by an outdoor light. Experiment with different locations until you find a spot that works well. [13]
    • Place the trap in a spot that won’t be knocked over by pets.

Making a Fan Trap

  1. Choose a piece of mosquito netting that is a similar size to the back screen of the box fan. If the net is too big, trim the net down to size with a pair of sharp scissors. [14]
    • Purchase mosquito netting and a metal box fan from a hardware store.
  2. The magnets will latch onto the metal screen and keep the netting securely in place. Use magnets that are marketed as “powerful” or “super strong”.
    • Use extra magnets if the netting comes loose.
  3. For example, measure 1 cup (240 mL) of water and 1 cup (240 mL) of isopropyl alcohol into the spray bottle. Shake the bottle vigorously for 10 seconds to combine the liquids. [15]
    • Purchase isopropyl alcohol from a hardware store.
  4. The strong air movement will pull any lingering mosquitoes into the meshing. Set the fan to the highest setting to achieve the best results. [16]
    • Place the fan in an area where there are lots of mosquitoes, such as by an outdoor light.
  5. The alcohol and water solutions poisons the mosquitoes that are trapped in the netting. Liberally spray the netting with water until the fabric is soaked.
    • Insects will eat the dead mosquitoes overnight, leaving you with clean mesh.

      About This Article

      Article Summary X

      To make a mosquito trap, fill a bucket halfway with water and mix in 4 drops of dish soap to remove the surface tension of the water. As a result, the mosquitos will drown when they try to lay their eggs in the water. If you want to make a smaller trap, cut off the spout of a 2-liter soda bottle and use the remaining bottom of the bottle to mix together 1 cup of sugar, 1 cup of hot water, 1 teaspoon of active dry yeast, and 1 cup of room temperature water. Cover the bottle with plastic wrap and leave it somewhere warm for 1 week, so the yeast ferments and begins attracting mosquitos. Then, tape the spout you removed upside down inside the bottle to create a funnel, and leave the trap somewhere with mosquitos. For more advice, including how to make a fan trap, read on!
