The little black bugs in the bathroom appear again

The second method, first we use a wet towel rolled around the floor drain, then align the mouth of the insecticide pipe with the mouth of the drain and spray a few times, use a wet towel to wrap around evenly, spray insecticide to prevent odors from escaping.

After spraying, we use this wet towel to seal the floor drain and open it again a few hours later to kill small flying insects in the pipe, this is a very practical method.

Third method, we prepare a kettle of boiling hot water, then pour it into half of the drain, to destroy the oil slick in the drain and the bug eggs that exist in the drain.

Then we prepare a container, pour about three spoons of glutinous rice flour into it and squeeze two drops of dishwashing liquid into it. We dissolve them in hot water, adding a little water will be more effective. Next, we let the flour melt completely.

Then we flush the alkaline water directly into the drain. The alkalinity is very strong, it can kill the eggs in the drain, and the detergent is used to better clear the drain and prevent the drain from smelling! After our water is drained, we will see a lot of heat coming out of the drain, and we need to wait quietly for five minutes.

Then we boil a pot of hot water and pour it all down the drain, we clean it once a month to make sure your family won’t have little flying insects all summer long!
