Speaking of coffee grounds, can you think of any functions, deodorization or dehumidification? Now the US Environmental Protection Agency actually says that mosquitoes hate the aroma of coffee, burning coffee grounds, or sprinkling them directly on flower beds or at home, which can keep mosquitoes away. Let's take a look at the results.

This gentleman really should not be surprised. When it comes to coffee grounds, everyone thinks it is super easy to use, but the deodorant cigarette butt may not have reached its CP value to the highest point, because it can also defend against mosquitoes.

When summer comes, they are afraid of mosquitoes. Both the US Environmental Protection Agency and Japan have confirmed that coffee grounds can prevent mosquitoes.

After taking the coffee liquid, do not throw away the coffee grounds, air-dry, ignite and burn, and then sprinkle the burning residue nearby. Mosquitoes dare not come near because of their "special smell." when the reporter got the park with the largest number of black mosquitoes, many mosquitoes had disappeared, but the smell seemed to make people want to run away.

People: "it stinks. I don't like the smell. I don't want to try it. I don't know how to do it, and there's too much smoke."

People: "give it a try, but it is not suitable for children to be very young, (why), because it is not suitable, because it will …" That, (smoke), yes. "

The smell is really bad, no wonder mosquitoes don't want to come near. Many people do not worry that the anti-mosquito liquid chemistry is not natural, it is like hanging garlic, or air-dried orange peel and burned moxa grass at home, but the effect is actually limited.

Tsai Cheng-fang, a doctor at National Taiwan University: "We know that coffee grounds are put in potted water, as if insects lay eggs in it and are less able to hatch. in fact, when you go to develop smoke, there will be some mosquito repellent effects, similar to mosquito incense."

Mosquito control, believe it or not, next time you make coffee, you might as well leave the residue to have a try.
