They can't drive away, they can't fight, and they circle around the house at will.
What the hell are these little flying insects? Where did it come from? How to eliminate it? "Life Times" (search for "LT0385" in WeChat to pay attention) invites experts to teach you a set of practical insect control tricks, you may wish to take advantage of the winter to completely remove insect eggs.

What the hell is the little black flying insect?
Insects are temperate animals, and when it is hot, the body temperature rises and the mobility is enhanced. The most common flying insects in our home are the following three types:
01
Common in the kitchen: fruit flies
After eating watermelons and grapes, the melon peel is thrown late, and the little black worm flying around in the kitchen is it.
Different fruit flies have different feeding habits, some often use molasses to obtain nutrients on ripe melon fruits or rotten plants, and some feed on tree sap or pollen.
Fruit flies can lay eggs under the peel of the fruit. When we return home after buying fruit, the eggs of the fruit fly come to the kitchen and gradually develop into flying fruit flies.
Fruit flies mostly grow up in a pollution-free environment and rarely carry germs, so they generally do not harm the human body.
Precautions:
Pay attention to keeping the fruit fresh, eat the bought fruit as soon as possible or put it in the refrigerator in the freshness layer; try to immediately discard spoiled food and peel garbage, and keep the trash can range clean. It is recommended to buy a lidded trash can.
02
Common in toilets: moth midges
Moth midges are also known as moth gnats (pronounced ruì). Although you've rarely heard its name, you're certainly no stranger to this little bug. It is a common flying insect in the toilet.
Moth midge larvae live on the walls of sewers and sewer pipes and feed on sewage sediment, decaying plants and microorganisms.
Most of the moths in the home fly up through sewers or toilet crevices.
It is a common nuisance pest in the bathroom, and the sink, damp rag, and water on the floor are all excellent environments for its growth.
Although they do not transmit diseases, they are easily inhaled into the respiratory tract and also affect visual refresh and indoor cleanliness. If left unnoticed, it can also contaminate underwear, causing pathogenic microorganisms to invade the genitourinary tract and cause infection, especially in women.
Timely dump the accumulated water in indoor and outdoor containers, remove the accumulated water in the floor and sink, and keep the outdoor water ditch unobstructed.
The sewer pipe should have a water retention bend to ensure that the air inside the pipeline is relatively isolated from the air in the room to prevent small insects from breeding in the pipeline. Floor drain to buy "three defenses", the bottom has an iron mesh, with a strong closure, can effectively prevent insects.
03
Common in rice: rice moth
Grains such as rice and millet have been left for a long time, and there is a small moth the size of a fly that often lurks in it, which is the rice moth.
The scientific name of the rice moth is the pink borer. They feather into adult insects in mid-to-late June and are mostly nocturnal and difficult to eradicate. The appearance of the rice moth means that the grain in the family has to be taken out to bask in the sun.
Families with few people try to buy small packages, it is not recommended to hoard rice; the rice bought should be sealed in the bag, or packed into a box (box) with a lid, sealed and stored in a dry and cool place, not placed in the kitchen and other places with high temperature and humidity.
Prepare an appropriate amount of peppercorns and three pieces of gauze, wrap the peppercorns in gauze and put them in the upper, middle and lower parts of the rice. Peppercorns are natural antioxidants, and their special taste has an insect repellent effect.
In winter, the best time to deworm
Winter is the most important and effective insect control time of the year. Winter pest control is more effective with half the effort, mainly for three reasons.
Low insect activity
In winter, the insect activity is low, the density is low, and the concentration is hidden, and most of them are in the state of egg eggs or "hibernation".
Cockroaches, mosquitoes, mites, bed bugs, etc. are the most common household pests, taking cockroaches as an example, usually 1 cockroach can breed 40 small cockroaches, if not controlled, let it reproduce freely, theoretically can reach thousands of them after one year.
Taking advantage of its characteristics, winter insect removal can reduce the reproduction of a large number of insects.
Live in a warm room
Insects prefer to live in warmer interiors in winter, while modern home environments are complex and have many gaps, providing them with natural habitats.
Facilitates the removal of eggs
Pests are all local "production", and the prevention and control of the self-environment is very necessary.
It is almost impossible for most household pests to actively spread long distances across regions, and even mosquitoes with a large range of activities fly at a distance of only about 400 meters.
Therefore, the removal of eggs from the environment can effectively control the number of pests.
5 tips for pest control at home
Household pest control should mainly start from environmental governance, and if necessary, adopt some physical and chemical control methods, specifically there are five ways:
Clean often
Household pests are mainly cereal pests and storage pests. Common grain pests such as rice worms and cockroaches are mainly hidden in food containers such as rice tanks, noodle bags, and cabinets.
Regularly clean up dead corners such as kitchens and bathrooms;
Seal flour, sugar and other ingredients;
Food do not stay overnight;
The garbage is dumped in time.
Ants, mites and other storage pests often appear in closed environments such as wardrobes and cabinets, and it is necessary to pay attention to regular turning, drying more, and shaking.
The dead corner of the water storage in the bathroom should be kept dry, and the water in pots, vases, floor drains, etc. should be cleaned up in time.
Because when cleaning a room, it is also the time when pollutants in the air are most dense. When cleaning a sofa, mattress or carpet, hidden large amounts of bacteria, dust mites, and dander will also float in the air. At this time, it is best to wear a mask to ensure that the window is open for ventilation.
Boil in hot water
Items that are in direct contact with people, such as rags, tableware, kitchen utensils, etc., can be cooked at high temperatures to play a role in disinfection and sterilization and removal of insect eggs.
Even some dishes and chopsticks that are not used frequently should be cleaned frequently to avoid mutual contamination. It is recommended to wash frequently touched household items such as clothes, sofa covers, carpets, and towels that have not been worn for a long time, and it is recommended to wash them at least once a month.
Freeze at low temperatures
In the environment of ultra-low temperature for a long time, most bugs have difficulty surviving. In the case of cockroaches, for example, they die at -8°C.
In the cold and dry winter, mattresses, sheets, quilts, clothes, etc. can be taken outdoors to dry regularly, and insect eggs can be killed by low temperature freezing.
04
With the help of insecticidal tools
When small insects appear, they can be killed with a variety of tools. Mosquito coils, insecticides, electric mosquito beats, sticky insect plates, etc. have good results.
However, it should be noted that the use of electric mosquitoes should be kept away from flammable items such as pesticides, flower lotion, hair spray, nail wash water and so on.
Electric mosquitoes will produce electric sparks when they are electric mosquitoes, and the main synthetics of these items are esters, alkanes, hydrocarbons and aromatics, which are extremely flammable and dangerous to meet.
05
Appropriate medication
Due to the fewer windows in winter, it is not recommended to use a large amount of medication when deworming. However, if there are still insects after the above treatment, appropriate medication can be used. When pest control in winter, ventilation should be done well.
For example, cockroaches in kitchens and bathrooms and other places where insects are often infested, with "small amount, many points, and wide coverage" as the principle of release, focusing on cockroach bait.
When spraying insecticide preparations, try to spray the agent on the wall, gap, corner, do not spray in the air, reduce the harm to the human body. ▲
