1. To eliminate cockroaches, we must first ensure environmental sanitation, clean up in time, including toilets and sewers, and clean up garbage in time. Don't leave a sanitary corner at home, don't put food in the open air in the kitchen, don't leave stagnant water at home, and block the gap in time to prevent cockroaches from breeding. Check carefully, even the old computer case. People living in a building had better act in unison, so that cockroaches have nowhere to hide. 2. First, find out where Xiao Qiang, the cockroach at home, is hiding. Cockroaches like hot, dark and humid places. Pay attention to water sources, food-rich kitchens, restaurants, bathrooms, sewers, trash cans and so on. Small cockroaches can get into cracks 0.5 mm thick. Adult male cockroaches can get into the gap of 1.6 mm, and female cockroaches with eggs need to hide in places 4.5 mm or two coins thick, especially in narrow and tight gaps, such as gaps between furniture. Any gap larger than 1.6 cm is a refuge for cockroaches. Cockroach nests will also be built where paper bags, boxes and corrugated paper piles are piled up. Some people pile books, newspapers, magazines or cartons next to the refrigerator. The damp and warm refrigerator is a hotbed of cockroaches, and these cartons have become the best breathing space for cockroaches. Cockroach nests are generally hidden in operating rooms, laundry rooms, heating boxes, behind televisions, computers and refrigerators, and in kitchens and sewers. If you want to wipe out the cockroach completely, you must find its nest and kill its eggs. You know, an ordinary cockroach can breed tens of thousands after half a year! In order to eliminate cockroaches, you must do the following work: a. Clean up garbage and unused items, especially books, newspapers and magazines at home; B. Check the bottom and back of furniture, as well as hidden places such as false ceilings, air ducts and wire troughs; C. Fill the cracks and gaps on the ceiling, wall and floor with non-thermal insulation materials to achieve the best sealing effect. D all cockroach remains and egg sheaths must be crushed and removed to prevent egg sheaths from hatching. (1: The egg sheath must be burned. 2: Rush into the sewer. E try to avoid furniture made of aluminum, stainless steel, plastic, etc. This kind of furniture is easy to wash and has no heat preservation effect, so cockroaches are not easy to survive. It is best to keep furniture away from the wall, so it is not easy to hide cockroaches. 3. What do cockroaches eat? Cockroaches have similar habits to humans, and like fermented foods rich in starch or sweetness, such as bread, cream, beer, fried flour, sesame oil, brown sugar and onions. Among them, German cockroaches, which are common in families, prefer fatty foods, while American cockroaches prefer sweets and beer. According to the habits of cockroaches, you must cut off their food sources. A. Keep the residence dry and clean: delimit strict eating areas, and no eating is allowed except the dining room and kitchen. Pay attention to the cleanliness of the kitchen and bathroom, and no water is allowed. B. Store food correctly and thoroughly clean up food residues after feeding pets. (For cats and dogs at home, dog friends must pay attention) C. The trash can is completely emptied at least once a day. Tie the mouth of the garbage bag tightly before putting it. Don't eat in bed. 4. The pipes to prevent cockroaches from coming in extend in all directions, which is a rapid passage system for cockroaches. At night, cockroaches in the drainage ditch will crawl into the room in droves along the drainage pipe and climb out from the gaps in the drainage holes, walls and doors and windows. To prevent cockroaches from entering the house, we must do the following: install screen doors and screens, or add fine nets at drainage holes; At night, the external drainage holes at home should be covered to prevent cockroaches from entering. Close the holes in the external wall, floor and platform so that the pipes and wires of the split air conditioning system can pass through or install the system. Coat a layer of vaseline with a width of at least 10 cm around the dry drainage hole to prevent cockroaches from crossing the hole; Install barbed wire with a mesh width of 2 mm on the drainage hole. 5. Catch cockroaches at 8 ~ 12 pm, suddenly turn on the light to search, kill adults and nymphs, and kill them for several nights before the cockroach breeding season, which can greatly reduce the insect density. Burn cockroaches, eggs and nymphs hiding in various gaps with hot soap or washing powder. Carefully fill and smooth the gaps in stoves and cabinets that are easy to hide cockroaches. Bamboo, wooden furniture, drawers, etc. Places where cockroaches live together can be scalded with boiling water. Mix oil with No.0 ink, add a little sesame oil, spread it on kraft paper, sprinkle some sugar in the center of the paper, and put the paper on the stove, cupboard, etc. I'll collect it in the evening and morning. Cockroaches get stuck when they are active. Generally, the validity period is 10 day. HD and others also sell special sticky paper. 6. How to use cockroach killing drugs: There are various cockroach killing drugs in various stores, so I won't go into details here. It should be noted that cockroaches like to repeat the route, and the medicine will be effective if it is placed in the right position. Drugs should be placed or sprayed in cockroach nests and routes. The location of the cockroach nest can be seen above, and the route should be observed. You know, cockroaches have lived on the earth for more than 300 million years and have strong adaptability. It is said that the only creature that can survive after the atomic bomb explosion is it. Isn't it awesome? Cockroaches will quickly develop drug adaptability in the next generation, and when a drug fails, it will be changed. (Be sure to use biological cockroach killing drugs that are effective in environmental protection and harmless to people, such as Xiaotaijian and Poisonous Island. ) In the process of pesticide application, the food and water of cockroaches should be removed, because cockroaches are hungry but not dry, especially for pregnant female cockroaches with eggs, they must have enough food and water, otherwise the egg sheath cannot hatch. 7. Wear gloves when handling cockroach carcasses; The area or equipment (including gloves) contacted by cockroach carcasses should be cleaned and disinfected with household disinfectant as soon as possible. 8. Ways to drive away cockroaches: Cockroaches use the bristles on their tails to detect the movements around them, just like hearing organs, which are very sensitive. So there was an instrument to drive away cockroaches like a mouse. Driving away will hurt the neighbors. Suggest elimination. 9. Does planting flowers to avoid cockroaches have anything to do with controlling cockroaches? A little bit. It is said that cockroaches don't like some plants, such as green radish. Why not try to beautify the environment and avoid cockroaches? 10. Always check anything you buy or take home. You'd better make sure before entering the house. Especially what YARDSALE bought second-hand. For example, I once helped my friend repair the computer, and when I opened the case, I got a ... as a thank-you gift, haha. Spiders, scorpions, ants, parasitic flies, parasitic bees, toads, lizards, birds and mice are common natural enemies of cockroaches. However, Blattella germanica is an exotic species in China, and no effective natural enemy has been found yet. Coupled with its unique high fertility, it has quickly become the first of the four pests in China in recent years.

Encyclopedia of cockroach killing methods

The existing cockroach control measures include environmental control, physical control, chemical control and biological control, each with its own characteristics. (1) environmental control. All crevices and holes where cockroaches can hide should be blocked and filled with cement or paint, and sundries should be removed to improve sanitary conditions. (2) Physical prevention. Hot killing and freezing killing. Cockroaches have poor heat tolerance. When the temperature reaches 60 degrees or above, they will die within a few minutes and can kill the eggs in the egg pods. The common method is to put boiling water into the kettle and pour it into the hidden gap of the cockroach to burn it. You can also kill it with a hair dryer. As long as it is set to the hottest, it will die in a few seconds. If the articles and furniture that roaches inhabit are moved to a place below -5- 10 for 30 minutes, roaches will freeze to death. Trapping method. The way to trap cockroaches is to put the bait into a cockroach trap box or a tin bottle coated with insect repellent. Sticky catching method. Put some bait in the middle of the sticky cockroach paper and stick it in the place where cockroaches often move. (3) chemical control. Chemical spraying technology. Close doors and windows and exhaust facilities of electric fans when spraying. After spraying, it should be sealed for more than 2 hours to prevent drug loss and cockroach escape. At the beginning of spraying, spray a circle of medicine on doors and windows to prevent cockroaches from escaping from doors and windows. Surface spraying should be from outside to inside and from top to bottom. In places where cockroaches are concentrated, direct spraying will stimulate cockroaches to flee everywhere. Cockroaches should be sprayed on the periphery of the place where cockroaches are concentrated, forming a closed circle and spraying from the outside to the inside, so that cockroaches can get enough doses when they run outside. For places such as crevices where cockroaches inhabit, you can spray a 30-50 cm medicine belt around them first, and then spray wine in the crevices. Smoke and fumigation. This technology can be used to kill bacteria in closed places. Poison bait, 0.5- 1 g/m2, is placed in the place where cockroaches often move. Powder. It should be placed in a place frequented by cockroaches, so that cockroaches can contact with poisons, which has contact and stomach killing effects. The duration is long, usually 1-2 months, but it should be moisture-proof. Glue bait is moist and delicious to cockroaches, with long duration, safety, high efficiency and convenience, and it is not easy to produce drug resistance, and it spreads toxicity among cockroaches, leading to cockroach death. At present, gel bait is an effective method to kill cockroaches. (4) Biological control. This is the most effective way to kill cockroaches now. "Poison Island", which is the only biological cockroach killing product in the world at present.
