DIY Mosquito Traps With Yeast, Dry Ice, or Buckets

Mosquitoes can be a real nuisance, especially in the warmer months. Their bites can leave itchy welts, and some species even transmit dangerous diseases like West Nile virus and malaria. Keeping mosquitoes away from your home and yard is important for comfort and health. While commercial mosquito traps and professional pest control can be expensive, there are several effective DIY mosquito trap options you can make at home using common household items.

Yeast Trap

One of the simplest DIY mosquito traps to make uses active dry yeast, sugar, and water. The carbon dioxide produced from the yeast fermenting the sugar attracts mosquitoes, especially species that prefer to bite birds. Here is how to make a simple yeast mosquito trap:

What You’ll Need

  • 1 cup warm water
  • 1/4 cup sugar
  • 1 packet active dry yeast (about 2 1/4 teaspoons)
  • 1 two-liter plastic bottle, with cap
  • Something to mix with like a long wooden spoon

How to Make It

  1. Mix the warm water, sugar, and yeast together in the plastic bottle. Stir to dissolve.
  2. Leave the cap off the bottle. The yeast will start reacting with the sugar, producing carbon dioxide gas that will escape from the opening and attract mosquitoes.
  3. Place the yeast trap outside in an area where you want to control mosquitoes, such as near a patio or garden. Position the opening of the bottle away from wind.
  4. Replace the yeast mixture every 2 weeks for the trap to remain effective. The yeast will stop making gas after a while.

This simple, all-natural trap can help reduce mosquitoes without using harsh chemicals. The yeast smells attractive to mosquitoes but not too strong for humans. For best results, use a few traps around your yard.

Dry Ice Trap

Another home mosquito trap option relies on dry ice. The carbon dioxide vapors released from the dry ice attract mosquitoes very effectively. Here is how to make a simple dry ice mosquito trap:

What You’ll Need

  • 1 to 3 pounds of dry ice (from a grocery store or ice supplier)
  • An insulated cooler or styrofoam container
  • A large, shallow pan that fits inside the cooler
  • Something to safely handle dry ice, like gloves or tongs

How to Make It

  1. Put on heavy gloves or use tongs to handle the dry ice, as it can cause frostbite burns. Place the dry ice in the insulated cooler or styrofoam container.
  2. Fill the shallow pan about halfway with water and place it on top of the ice in the cooler.
  3. Position the cooler outside in an area where you want to trap mosquitoes. Keep the lid open.
  4. As the dry ice sublimates (turns from solid to gas), the carbon dioxide vapors will flow out of the cooler and attract mosquitoes to the water-filled pan.
  5. Replace the dry ice every 24 hours for the trap to keep working. Use caution when handling the dry ice.

The advantage of a dry ice trap is that it releases large amounts of carbon dioxide to attract mosquitoes. No mixing or prep is required. Just be sure to take safety precautions when handling dry ice.

Bucket Trap

For an even easier DIY mosquito trap, you can use two common buckets and some wire mesh. The design takes advantage of a mosquito’s natural instinct to fly up toward vertical shapes. Here is how to construct a simple bucket mosquito trap:

What You’ll Need

  • 2 five-gallon plastic buckets, one with a lid
  • Wire mesh screening or netting
  • Duct tape
  • Something smelly to attract mosquitoes, like spoiled fruit, yeast solution, or active dry yeast

How to Make It

  1. Take the bucket without a lid and cut out the bottom, creating a tube shape. This will be the outer sleeve.
  2. Take the wire mesh and roll it into a tube that fits neatly inside the outer sleeve bucket, creating a mesh inner sleeve.
  3. Put smelly bait inside the inner mesh sleeve, such as overripe fruit, 1 cup of yeast solution, or a packet of active dry yeast.
  4. Duct tape the mesh sleeve into place inside the outer sleeve.
  5. Put the outer sleeve bucket over the top of the other bucket with the lid still on.
  6. The mosquitoes are attracted to the smelly bait inside the mesh sleeve. When they fly up toward it, they become trapped between the inner sleeve and outer bucket.
  7. To kill and collect the mosquitoes, put some water in the bottom bucket or use insecticide on the mesh.

This DIY bucket trap takes advantage of mosquito behavior patterns to lure and capture them. Rotating a few of these traps around your property can significantly reduce mosquito populations.

Tips for Any DIY Mosquito Trap

  • Place traps near mosquito breeding grounds like standing water.
  • Position traps in shady areas during hot weather.
  • Check traps daily and dispose of collected mosquitoes.
  • Replenish bait and refresh traps regularly for best performance.
  • Use traps from early spring through fall when mosquitoes are most active.
  • Supplement traps with mosquito repellents when outdoors.
  • Make sure children and pets don’t disturb the traps.

Frequently Asked Questions

What homemade mosquito traps work the best?

Dry ice traps are often considered the most effective DIY option, as the carbon dioxide released mimics human breath and attracts mosquitoes very well. Yeast traps and bucket traps also work if made properly.

How long does a homemade mosquito trap last?

DIY mosquito traps need to have bait replaced about every 1-2 weeks to remain effective. Dry ice traps require new ice daily. Check individual trap instructions for refresh rates.

Where is the best place to put a mosquito trap?

Focus on placing DIY mosquito traps near where mosquitoes breed and congregate, such as near standing water sources, shady damp areas, under decks, and by gardens and patios. Avoid excessive wind.

Can homemade mosquito traps completely eliminate mosquitoes from a yard?

While DIY traps can significantly reduce local mosquito populations, it’s difficult to eliminate all mosquitoes with traps alone. Use traps strategically in combination with repellent, protective clothing, and mosquito dunks.

Are DIY mosquito traps safe for children and pets?

Most homemade traps pose little risk for kids or pets, but take some basic precautions. Place traps out of reach, supervise young children outdoors, and don’t use insecticides. Teach kids to avoid open traps.


Mosquitoes can quickly go from nuisance to health hazard during warm weather. With some simple homemade traps and creativity, you can cut down your mosquito population and enjoy the outdoors more comfortably. Yeast, dry ice, and bucket traps offer budget-friendly and effective options using materials you likely have on hand. Strategically place several DIY traps around your yard and refresh them regularly for best results. Along with protective clothing and repellent when outside, homeowners can take control this mosquito season using safe, easy-to-make traps.
