There are cockroaches in my house, but I can't kill them with drugs. What should I put in it? Thank you, everyone.

Cockroaches are nocturnal insects, which are extremely fertile. If the climate is mild and moderate, they can breed a nest of 40 to 50 in ten days. So how do you kill cockroaches? (1) Cockroaches mainly live in the kitchen. They live in all the gaps between the cabinet frame and the wall, in the cracks in the wall, and in the drainage pipes of the kitchen. You can spray pesticides to plug the gap and scald it with boiling water. (2) If there are too many cockroaches in the decorated room, it's best to close the doors and windows and use alcohol lamps to light 10% Didi Wei. Burning for an hour or two can kill a lot of cockroaches. But remember, cockroaches are extremely vital, and sometimes they are just in a coma, not really dead. So you can't throw it away as garbage. You'd better scald it with boiling water. Otherwise, many cockroaches will wake up in ten minutes, which is equivalent to "releasing tigers to the mountains". (3) Put the sticky paper in the place where cockroaches often haunt. This method has little effect, which is equivalent to "waiting for the rabbit". (4) Cockroaches should not be beaten by flies or trampled to death by their feet. It is best to stick one on the other with cockroach paper, which is very accurate and effective. Stepping on your feet will spread a lot of germs and viruses on cockroaches everywhere. "There is no fixed mode to kill cockroaches, so it is necessary to adapt to local conditions." Section Li of the Disinfection and Insecticidal Service Team of Taiyuan CDC introduced some valuable experiences they had explored from actual combat. Before killing cockroaches, you must thoroughly remove the dead corners in your home, especially some furniture items with interlayers that have not been used for a long time. This is the best place for cockroaches. Secondly, we should plug some gaps in our home, which are the hiding places of cockroaches. In general, comprehensive prevention and control should be carried out to kill cockroaches. The methods and drugs to kill cockroaches include sticking paper, fumigation, powder contact, poison bait trapping and so on. The types and products of drugs include aerosol, powder, poison bait, spray, fumigant, cockroach house and other pesticides. Among them, aerosol, powder, spray, fumigant and so on are used. Killing cockroaches has the characteristics of quick effect, but the disadvantages are that cockroaches flee everywhere, have a strong choking smell, have short efficacy, rebound quickly and are prone to drug resistance; When killing cockroaches, doors and windows should be closed to evacuate people. After killing cockroaches, open the window for ventilation to prevent people and pets from being poisoned and polluting the indoor living environment. Therefore, indoor medication should be based on environmental protection pesticides, and chemical pesticides should not be used to protect people's health. At the same time, we should also use non-volatile, long-lasting poison bait (gel bait) with high cockroach killing rate, or ask a pest control (PCO) qualified insecticidal company to provide professional cockroach killing services. Section Li said that they used different methods to kill cockroaches in public places such as residents' homes, hotels and bathing places. It is not recommended to spray cockroaches in the family, but generally use poison bait to trap them. Because the spraying method is expensive and medicinal, it is easy to waste money and resources when used at home. Poison bait trapping method is economical and effective, but section Li reminds everyone to pay attention when using poison bait, and try to put it near the cockroach nest. According to the habits and experience of cockroaches, section chief Li draws the conclusion that greasy, warm, damp and dark places are often cockroaches' nests, specifically, on the back of telephones, televisions, electric meter boxes, refrigerators, compressors and heating boxes. In addition, cockroaches are easy to hide in some dead corners of the kitchen, and attention should be paid to these places when baiting. Cockroaches can be killed all year round, and the best season is early spring without stopping heating. At this time, there are fewer cockroaches and they are all concentrated in the warm back, which is easy to distribute drugs. Be careful not to let the bait get wet or wet when releasing the bait. Once wet or soaked, the taste of the medicine will change, and cockroaches will not eat it. In response to some citizens complaining that cockroaches can't be killed, Section Li said that if you buy good medicine, you still have to use it. If used properly, the drug can get good results after 2~4 times. Domestic poison bait is relatively cheap, the price of a pack is 2-6 yuan, and the price of spray stock solution in commercial places or units is 60-65 yuan/kg. After the citizens put the medicine in a place frequented by cockroaches, they have to change the medicine once a month, and they will burn the cockroaches when they find their bodies. Section Li particularly emphasized that cockroaches' bodies should not be littered at will, because there is an egg sheath at the tail of cockroaches, which contains a large number of eggs. Even after cockroaches die, these eggs will hatch. Only by burning their bodies can cockroaches be completely extinct. Some citizens think that it is effective to treat cockroaches with dichlorvos and other poisons. Section Li pointed out that this strong poison is harmful to people and animals on the one hand, and cockroaches will die if eaten on the other, which is not a good phenomenon. Cockroaches have the habit of eating dead bodies. Cockroaches that eat poisonous bait will not die immediately. If they return to their nests and die, other cockroaches will be poisoned if they eat their carcasses, so that a whole nest of cockroaches can be eradicated. For all kinds of cockroach killing drugs on the market now, section Li said, don't blindly believe in advertisements, and don't be greedy and cheap. Be sure to go to a regular pharmacy to buy medicine. It is best to kill cockroaches together in the whole community or unit. If you kill cockroaches in your own house, cockroaches from other places will invade again at any time. Section Li also said that if the whole unit or community can be combined to kill cockroaches, it is best to invite a professional and qualified cockroach killing team, such as the disinfection and insecticidal service team of Taiyuan CDC. They have rich professional knowledge and practical experience, but the cost of hiring a cockroach killing team is high, which is not easy for a family to accept and is unnecessary. But it is still very cost-effective for everyone to work together and share the cost, and the effect is much better than that of individuals working alone. Section Li reminded the public that the drugs used by the CDC to kill cockroaches, rats and ants are only available in the preventive health clinic of Taiyuan CDC on Xinjian South Road, and the disinfection service department is also in this place.
