DIY Mosquito Trap #1 Plastic Bottle Trap

This simple homemade mosquito traps really does work quite well, but will have to be refilled on a regular basis to continue being effective. Sugar and yeast are used for mosquito bait. The neck of a plastic bottle a carbon dioxide pathway and serves as an entrance to the trap. It has a “Hotel California” effect – the bugs can get it, but they never check out. When the trap is made properly, the mosquitoes eventually exhaust themselves trying to get back out of the bottle and fall to the bottom and die.


• Yeast – 1 package of dry: approximately 3 teaspoons • Brown sugar – ¼ of a cup • 1 cup of hot water • Plastic bottle – you can use one 2-liter plastic bottle or several single plastic water bottles placed around the perimeter to where you are recreating or working. • Scissors or knife. • Duct tape • Black paint or construction paper


1. Remove the cap from the bottle and discard. 2. Cut the top part of the bottle (the neck and funnel area) off. You want to cut just below the flare of the bottleneck. 3. Turn the bottleneck and funnel piece upside down so the mouthpiece where the cap was is pointing to the bottom of the bottle. 4. Push the inverted bottleneck down slowly and carefully. You must leave enough space at the bottom to hold the yeast and sugar mixture – at least a couple inches. 5. Tape the two bottle pieces together to hold the funnel section firmly in place. This helps ensures no gaps will appear between the two bottles that would allow the mosquitoes to escape. 6. Paint the lower section of the bottle or tape black construction paper around it to help attract the insects. 7. Make and pour in the yeast, sugar, and water mixture – see instructions below.

How to Reduce Itching and Redness From Mosquito Bites

The longer a bite goes untreated, the more likely it is to cause damage and itching. You can do several different things to reduce the itchiness and redness that the bites create.

How to Reduce Itching From Mosquito Bites

Use alcohol to treat the affected area right away. Rubbing alcohol on a cotton ball or using an alcohol wipe are both effective ways to address the area quickly. Refrain from scratching the area, as it can cause redness to show up sooner and will make the area itchier.

  • Baking Soda: If you want natural solutions to reduce itching, you can find most of the supplies in your home. Baking soda is one of the most effective solutions. Mix it with warm water to create a paste. Use a cotton swab to apply the paste to the area. Leave the paste on the skin for a few minutes before washing it off.
  • Apple Cider Vinegar: Soak a cotton ball in the apple cider vinegar until it becomes saturated. Grab tape or a band-aid to secure the cotton ball to the skin that is affected by the bite. Keep the cotton ball in place as the pain subsides.

How to Reduce Redness From Mosquito Bites

  • Aloe vera is a great topical treatment for many injuries and issues and is perfect to address the heat that comes with bug bites. Apply a bit of aloe to the area to feel relief.
  • Honey is another great way to eliminate swelling. Simply apply it to the area and rub it into the skin. Its anti-inflammatory properties make it a product you should reach for soon after getting bit.

5 Steps to Make a Homemade Mosquito Trap (with Plastic Bottle)

Follow the steps below to construct a mosquito trap that will reduce the number of mosquitoes on your property. The method is simple, and the items that you need for constructing a mosquito trap are easily available at any store.

The easy-to-make trap is organic and safe for your children and pets. Let’s have a look at what you’ll need to prepare a mosquito trap.

Items That You’ll Need for a Trap

You’ll need the following items for making a mosquito trap:

  • An empty two-liter plastic bottle or a similar-sized container
  • A razor knife
  • Spray paint
  • 1 cup hot water
  • 1/4 cup brown sugar
  • 1 pack dry active yeast
  • Duct Tape

Now follow the below steps to prepare a trap.1. Cut the Plastic Bottle

1. Cut the Plastic Bottle

Use a sharp razor knife to cut the top section of the bottle. Don’t cut from the middle. Mark the area from where the narrow neck of the bottle widens to meet the main body of the bottle. Cut the top section carefully without damaging the plastic of the rest of the bottle. If you are unable to mark the correct spot, mark the area at least four inches from the lid.

2. Prepare the Mixture

Now that you have built your container, now is the time to prepare the mixture or the mosquito bait. Follow the following steps to prepare the bait.

  1. Use a measuring cup to pour 1/4 brown sugar
  2. Heat the water and bring it to a boil
  3. Add the sugar into the hot water and wait for it to be completely dissolved.
  4. Allow the mixture to cool down. Dip your finger to check the temperature. It should ideally be between 120 and 130 degrees F. If you add the yeast in the hot mixture, the high temperature will kill it. However, if the temperature falls below the recommended range, the yeast will lose its effectiveness.
  5. When the sugar mixture reaches desirable temperature, add yeast. Pour the mixture into the bottle (the bottom part of the bottle).

3. Assemble the Trap

Once you have cut the top section, you are left with the two parts of the bottle the bottleneck and the bottom cylinders. These two parts are then rearranged to make the trap. The cut out can be used as a funnel. The top section, when inverted, resembles a funnel and can be used to offer a passage to mosquitoes.

But don’t push the funnel all the way to the bottom of the bottle. There has to be airspace between the funnel’s lowest point and the liquid’s surface. You have to leave some space between the two to add around a cup of liquid.

4. Block the Escape Route

To seal the edges of the funnel, wrap duct tape around the bottle to secure the funnel in one place. In order to keep the life of the mixture longer, cover the bottle with spray paint. This way the sunlight will not enter the bottle and your mixture will remain active for a longer period.

5. Place the Mosquito Trap at the Designated Places

Place the trap in your backyard, your window sills, or at any place where mosquitoes are higher in number. Be careful and do not put the trap in an area that you use the most. The main purpose of the trap is to lure mosquitoes and bring them inside the bottle. If you place in your sitting area, for example, the mosquitoes will not fall for the trap and will, instead, attack you.

As the sun sets, mosquitoes will come out of their hiding places to search for food. The carbon dioxide produced by the mixture will lead the mosquitoes to your death trap. For even more effective results, keep changing the mixture every two weeks.
