2. The sewer pipe should have a trap, so that the air in the pipe is relatively isolated from the indoor air, and insects are not allowed in the pipe.
3. Invite professional disinfection personnel for home treatment. Professionals can find out the location of the insect source and destroy it according to the field situation, and build a defense circle to prevent the insect from entering the family again.
4. Spray pesticides in places where insects are infested. After people leave the room, seal the doors and windows and wait for half an hour.
5. Clean the room, keep it clean, and don't provide a living environment for bugs.

Strong vitality, can be propagated in the wild or indoors, and when it happens in large quantities, it can cause great losses to some stored products. No reports of biting and spreading diseases were found.
Most of the insects are hidden in stale flour, rice and white flour that have been stored in residents' homes for too long. Common sprays and pesticides are used for culling, and the effect is average. To eradicate pests, it is necessary to start from the place where grain is stored, find out the source of pests and clean it up.
For example, boxes of rice, noodles and nuts stored at home should be regularly checked for bugs. Once found, clean it up immediately.
Extended data:
It is understood that the larvae of dermatophytes are extremely harmful and extremely difficult to control, and they are one of the important pests in the world. It can seriously harm a variety of plant products and feed on a variety of animal products, such as wheat, barley, cotton, fur, silk, textiles and so on.
In order to strictly control and prevent the introduction of pests, it is necessary to strengthen the on-site quarantine of imported cotton, conduct a comprehensive quarantine of its loading containers, means of transport, cotton itself and packaging, focus on quarantine pests and storage pests, find out the harm situation and pests, and once quarantine pests are found alive, fumigate and disinfect them in time to prevent the spread of the epidemic.
Is black midge poisonous? How to kill midges?
Find the problem
1, judge whether there are mites.
Be familiar with the general situation that may breed mites and pay attention to the morphological characteristics of mites. Dung balls and molting are the most common signs of breeding mites. You may also see adults and larvae. Most adult midges are oval, only slightly larger than needles. They are brightly colored, but most of them are dark gray or dark brown. Some species have yellow or white backs. A pimp is slow, and when he touches it, he rolls away. There are generally brown stripes on the larvae of dermatophytes, which spread to one side or both sides like long hair.
2. Explore the source.
The more places where dermatophagoides pteronyssinus, molting and dung balls are concentrated, the more likely it is the source of breeding. Pimps like textiles best. You can find them in blankets, especially when they are put in storage rooms or other dark places. But they also like to hide in clothes, upholstered furniture, or things made of fur or feathers. Non-textiles that attract mites include kennels, dog food, flowers and brushes. At the same time, check dark and quiet corners, such as ventilation pipes, corner boards, attics, etc.
Indoor governance
1. Vacuum the carpet.
Clean all the places in the house thoroughly with blankets. Pay attention to the main breeding sources, but clean the house with a vacuum cleaner to ensure that mites are removed. At the same time, use a vacuum cleaner to clean all places covered by decorative furniture or other textiles that cannot be cleaned by a washing machine. Once skin mites breed, clean the room once a day for at least a week, or several times. According to the specific situation, it even needs to be cleaned several times a day at first.
2. Throw away clothes that breed mites.
If a dress is bitten, you'd better throw it away. Keeping clothes that breed mites will increase the risk that the breeding source cannot be completely eliminated. Even if there is no dermatophagoides on the surface, there may be dermatophagoides.
3. Clean textiles.
All clothes not stored in sealed bags should be washed with soap and hot water. The same is true for fabrics such as sheets and towels. When the breeding situation is particularly serious, it is even necessary to steam clean carpets and soft furniture. Pimps are stubborn. Hot water will get rid of them more effectively than cold water. I suggest you use detergent, because soap can kill these pests.
4. Use pesticides.
Use aerosol or powder insecticide specially used for killing mites and spray it on the blanket according to the label instructions. Generally speaking, dermatophagoides pteronyssinus insecticides contain the most effective components for dermatophagoides pteronyssinus: chlorpyrifos, bencarbaryl and allethrin. In addition to large-scale treatment of blankets, local treatment can also be used to treat mites hidden in cracks and crevices. When using pesticides, add a bottle of insect growth regulator. This insecticide can control the growth of midges and prevent the reproduction of pests.
Try to spray boric acid solution in the place where mites breed, provided it is harmless to human body. This can kill almost every pest that comes into contact with it, but it can't be used on dark materials because of its bleaching effect. Take precautions when using pesticides. Wear gloves or protective clothing and stay away after spraying, because pesticides will spread in the air. And wash your hands after using pesticides.
5. Set traps.
Place glue containing hormones as a trap in cracks or crevices or other places where you suspect that skin mites breed. Setting traps with glue can kill pests and tell you how bad the situation is still.
Outdoor therapy
1. Set up obstacles around.
Spray liquid pesticides on the side and lower soil of the house. Outdoor treatment is particularly important when you suspect that the breeding source is an exhaust hole or other place connected with the outside world. For the best therapeutic effect, the barrier should extend to 2 to 3 feet (60 to 90 cm) above the house and 2 to 3 feet (60 to 90 cm) outside the house. At the same time, manage potential entry points. Windows, doorframes, air vents and drainage pipes may all be channels for mites to enter.
Step 2 remove the nest.
Move the nest or beehive near your home or yard. Midges usually lay eggs in nests, so leaving these nests near the house will increase the risk of breeding midges. Destroy or move the nest away from your home. If you put them in the yard, make sure that the bird's nest is far enough away from the house by the yard. Be careful not to irritate birds or bees when moving nests.
Realization of details
1, protect the easily damaged items.
Put out-of-season clothes in a plastic container or bag and seal the mouth of the bag. Open the closet door and dresser drawer for a few hours in the sun every day. It's hard to get into plastic bags, which are separated by the sun. You can also put cedar chips or mothballs in the storage place to prevent the spread of mites. Cleaning blankets regularly can also prevent mites from breeding again. Without dust and pet hair, the number of bugs will be greatly reduced.
2. Lock the doors and windows.
Any window or door without a screen should be locked as much as possible. Opening these passages will only make it easier for midges and other pests to enter the room. Mend every hole in the screen window. Because mites are so small, even the smallest hole can let them in.
Check the flowers carefully before moving them into the house.
Midges often stay on flowers and plants. Before moving the flowers into the house, check the leaves and remove unnecessary withered petals.
skill
If necessary, hire a professional. Professional exterminators are trained to use stronger and more effective chemicals to deal with insects, which may completely eliminate places with serious breeding.
You need to prepare
Vacuum cleaner, washing machine, washing powder, steam cleaner, insecticide, glue, plastic container or packaging bag, cedar chips or mothballs.
