What should I do if there are small bugs in the toilet?

There is often a small black bug in the bathroom, which should be called a gnat. So, what should you do if this bug appears in the bathroom? The moth is also known as the butterfly fly, the hairy midge (a kind of midge), belonging to the family of the diptera longhorned suborder (hairy midge):

The body length is 3mm, the body color is grayish-brown, the wings are covered with gray fine hairs, the wing mask is not obvious white fine spots, the antennae are long, the shape is similar to that of a moth, living near the home or in the environment of outdoor toilets and ditches, it is easy to see, but the small size is easy to ignore. It can be seen all year round in low- to medium-altitude mountainous areas. Adult gnats mostly stop on the nearest wall.

Gnats are not very capable of flying, often stopping on walls and not moving, and will only fly away when disturbed. Flew a short distance and stopped at a nearby wall. Control of gnats:

The most fundamental way to control gnats is environmental rectification; The number of gnats can be controlled as long as the container is drained, the floor or sink is removed, and the outdoor gutter is kept unblocked. The larvae that breed in the septic tank can be injected with insect growth regulators, etc., which can control gnats and white-bellied bush mosquitoes at the same time (high cost). Removal of adult worms:

The flight ability of the gnats is very poor, and the use of an electric mosquito swatter can effectively remove them. Synthetic pyrethroid sprays (pyrethrins) for general household use can be used for chemical agents.

Your home toilet should try to open as many windows as possible, ventilate, try not to stay in the toilet, keep it clean, the effect will be much better.

Your little black worm is flying out of the sewer, the little black worm is called a moth midge, a diptera moth midge, can swim in cold water, often use boiling water to water the drain of the sewer, or spray it with household spray insecticide a few times, it's OK!

The wings are so cute that I want to kill them.

Tell them that it is a paid public toilet, and see if they dare to come?

Put the door under your feet.

Make some lime and pour it on top. Keep it dry, and there will be no more bugs! How much pesticides are harmful to people! The main problem is dryness. My family lives in an old house.

The situation is basically similar to you, I'll get some lime and sprinkle the foot of the wall
