A Simple hand-made Mosquito trap ( Prevention of Dengue & other mosquito born diseases)
It’s just a mix of water, brown sugar and yeast.
1. Cut a plastic bottle in half, keep both parts. Can be soft drink
bottle.
2.Take the lower portion of the bottle. Dissolve the brown sugar ( or white sugar if you don't have brown sugar) in hot
water. Let it cool down to ~70 deg F /~ 32 deg C) (room temperature).
3.Add the yeast. Carbon dioxide will be formed and will attract the
mosquitoes.
4.Cover the bottle with a dark wrap and insert in the top portion upside
down like a funnel. Place it in a corner in your house.
5. In 2 weeks you will be surprised by the number of mosquitoes killed.
Additional Instruction: ( More details as your request):
Since mosquitoes are attracted to dark, moist places and carbon dioxide, you simply need to use this to your advantage in order to trap them. Midges prefer salt water, but the CO2 may still catch some of the pests, too. Making the mosquito trap is easy. You simply modify a plastic 2 liter bottle, fill it with a sugar, water, and yeast syrup, and cover it with black plastic to create the dark, wet, CO2 rich environment mosquitoes crave.
1.Procure an empty 2 liter bottle. Many name brands have started using some new style of bottle that does not work as well for this project. However, most store brands still have a 'traditional' plastic 2 liter such as: coca cola, pepsi, sprite, sunkit...
2.Rinse the bottle out, remove the label, and throw away the cap.
3.Cut the bottle to separate the top 1/3 from the bottom 2/3. You want to cut slightly below where the bottle begins to taper toward the top. You can either grab a pair of scissors and jump right in, or you can measure, draw a line, and make an even cut. I highly recommend the latter. To do this, hold a ruler against the bottle and find where you want to make the cut. I wanted my cut about 5" up the bottle. Use a permanent marker to make a line at this height. Proceed around the bottle, making marks every few inches at this same height. Then, place the bottle on its side. Use a ruler to slightly flatten the bottle and draw a line connecting your marks. Continue by turning the bottle, flattening slightly, and extending the line until you've made a neat circle all the way around. Now you can cut along the line with ease!
4.Boil 1 cup of water. Make sure to put the lid on to make the water boil more quickly.
5.Remove the water from heat and stir in 1 cup of brown/white sugar. Stir until the sugar is completely dissolved.
6.Add 1 c of 'cold' tap water and stir.
7.Wait for the water temperature to drop below 90 degrees Fahrenheit. If you add the yeast before the water has cooled sufficiently, the yeast will die. You may add a couple of ice cubes to hasten the process, but do not place the pan in your fridge or freezer. While the water needs to be less than 90, if it is too cold, the yeast cannot thrive. If you do not have a thermometer, put your wrist, or whole hand, in the water (yes, it will get sticky). If it feels about the same as your body temperature, it is still too hot. If it feels slightly cool, you're in business. It is better to err on the side of caution and have too-cool water instead of too-hot water because cool water does not kill yeast.
8.Once the water reaches the appropriate temperature, add 1 teaspoon of dry active yeast and stir.
9.Pour this mixture in the bottom portion of the bottle. I caught a fruit fly before I even got the top on the mixture!
10.Tape black plastic around the bottle. I used two doggie bags, but part of a trash bag or shopping bag works, too. I've seen other instructions online suggest using black construction paper. Construction paper fades very quickly and rips easily, so I cannot recommend this course of action.
11.Place the top portion of the bottle, cap end down, in the bottom portion of the bottle. If your liquid actually touches the bottle's lip, pour some of it out. There must be enough space for the insects to enter the bottle and become trapped.
12.Use tape to seal the two portions of the bottle.
13.Place your trap and let it get to work!
