Materials used: large beverage bottles, sugar, baking powder, etc.
Three steps:
1. The first step is to cut off the upper end of the beverage bottle. First, wrap it in a piece of waste paper to expose the part to be cut off, and then draw a line along the edge of the paper with a marker.
2. Remove the waste paper and leave a circle of marks on the beverage bottle.
3. Cut it along the mark with wallpaper knife or scissors, and don't throw away the cut top for later use. Add 200 ml of warm water to the bottle, which accounts for less than one tenth of the volume of the whole bottle of 2500 ml. Just make a rough estimate, and then add 50 g of white sugar to the water.
4. If the sugar you buy is packed in a bag of 500g, just add one tenth of it, and the requirement for the weight is not strict. Stir with chopsticks to melt the sugar. Then add 1 g baking powder to the sugar water. The package used is marked as 1 5g, and1g is of course one fifteenth of the total.
5. The baking powder will ferment the white sugar water and produce carbon dioxide. As mentioned earlier, carbon dioxide is the bait to attract mosquitoes.
6. Insert the upper end of the cut beverage bottle upside down into the lower end.
7. Such a trap is done. Mosquitoes are attracted to the bottle by carbon dioxide produced by sugar water fermentation, and they can't fly out any more.
8. Cut a thick paper of Zhang Shen color, measure it, and stick it with double-sided adhesive.
9. Wrap the drink bottle with this paper.
10. The opaque paper creates a dark environment in the beverage bottle, and mosquitoes love to hide in the dark. The self-made environmentally-friendly mosquito trap is really completed.
1 1. Put the homemade mosquito trap in the corner and other places where mosquitoes hide, and wait for these pests to bite!
12. The trace carbon dioxide produced by sugar water fermentation will not cause any pollution to the environment, and it can be reused as long as the sugar water and yeast are replaced every two weeks. It can be said that this is a real "environmental protection" mosquito trap.
