2. First look for where the cockroach Xiaoqiang at home is hiding. Cockroaches like hot, dark and humid places, and they should pay attention to water sources, food-rich kitchens, restaurants, bathrooms, drains, trash cans, etc. Small cockroaches can get into 0.5 mm thick cracks. Adult male cockroaches can get into the crack of 1.6 mm. Female cockroaches with eggs need to hide in a place 4.5 mm or two coins thick, especially in narrow and tight gaps, such as the gap between furniture. Any gap larger than 1.6 cm is the cockroach's shelter. Where paper bags, boxes and corrugated paper are piled up, cockroach nests will also be built. 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 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 sewer pipes. If you want to completely eliminate cockroaches, you must find the nest and destroy the eggs. You know, an average 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 underside and back of furniture, as well as hidden places such as false ceilings, air troughs and wire troughs.
C. Fill the cracks and crevices on the ceiling, wall and floor with non-thermal insulation materials to make the best seal.
D. All cockroach remains and egg sheaths must be crushed and removed, so as to prevent the egg sheaths from hatching. (1: The egg sheath must be burned. 2: Flush into the sewer.)
E. Try to avoid using plywood or ceiling wall for furniture, but choose furniture made of aluminum, stainless steel and plastic, which is easy to wash and has no heat preservation effect, so cockroaches are not easy to survive. It's best to keep the furniture away from the wall, so it's not easy to hide cockroaches.
3. What do cockroaches eat?
Cockroaches have similar habits to humans, and like starch-rich or sweet fermented foods, 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. You must cut off the food source of cockroaches for their habits.
A. Keep the residence dry and clean: define a strict eating area, and no food is allowed except the restaurant and kitchen. Attention should be paid to the cleanliness of the kitchen and bathroom, and no water accumulation is allowed.
B. Store food properly and thoroughly clean up food residues after feeding pets. (For cats at home, dog friends must pay attention)
C. Empty the trash can thoroughly at least once a day. Tie the mouth of the garbage bag before placing it.
D. don't eat in bed.
4. The pipeline to prevent cockroaches from coming in and extending in all directions is a rapid transit system for cockroaches. At night, cockroaches in the drainage ditch will crawl indoors in droves along the drainage pipe, from the drainage holes, walls and cracks in doors and windows.
To prevent cockroaches from entering the house, you must do the following: install screen doors, screens, or add detailed nets to drainage holes; At night, the external drainage holes at home should be covered to prevent cockroaches from entering. Seal the holes left on the external wall, floor and platform for the pipes and wires of split air conditioning system to pass through or install the system. Coat a layer of vaseline with a minimum width of10cm 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. When cockroaches are active at 8 ~12 o'clock in the evening, they suddenly turn on the light to search and kill adults and nymphs. Before the cockroach breeding season, they can be killed for several nights continuously, which can greatly reduce the insect density. Use hot soap or washing powder to scald cockroaches, eggs and nymphs hiding in various gaps. Carefully fill and smooth the gaps in stoves and cabinets that are easy to hide cockroaches. Bamboo, wooden furniture, drawers, etc. inhabited by cockroaches can be scalded with boiling water. Add a little sesame oil with No.0 ink blending oil, spread it on kraft paper, sprinkle a little sugar in the center of the paper to fry noodles, put the paper on the stove, cupboard, etc., and collect it in the morning at night. Cockroaches get stuck when they are active. Generally, the validity period is 10 day. HD and others also sell special sticky paper.
6. Method of using cockroach medicine: There are various cockroach-killing drugs in various stores, so I won't repeat them here. It should be noted that cockroaches like to repeat the route, and the medicine will be effective if it is put in the right position. Drugs should be placed or sprayed on cockroach nests and routes. The location of cockroach nests 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 their adaptability is super strong. 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 change the medicine as soon as a drug fails. (The drugs must use biological cockroach killing drugs that are environmentally friendly, effective and harmless to people, such as Xiaotaijian and Poison Island)
During the application, the food and water of cockroaches should be removed, because cockroaches are resistant to hunger and dryness, especially female cockroaches with eggs in pregnancy, and they must have enough food and water, otherwise the egg sheath cannot hatch.
7. Wear gloves when handling cockroach carcasses; The areas or equipment (including gloves) that roach corpses have come into contact with should be cleaned and disinfected with household disinfectant as soon as possible.
8. Ways to drive cockroaches: Cockroaches use the bristles of their tails to detect the surrounding movements, just like hearing organs, which are very sensitive. So there are instruments to drive away cockroaches like mice. Driving away will hurt the neighbors. It is recommended to eliminate it.
9. Does planting flowers to avoid cockroaches have anything to do with controlling cockroaches? A little. 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 home or bring into the house. It is best to confirm it before entering the house. Spiders, scorpions, ants, parasitic flies, parasitic wasps, toads, lizards, birds and mice are all common natural enemies of cockroaches. However, Blattella germanica is an exotic species in China, and its natural enemies that can effectively control it have not been found yet. In addition, it has a unique high fecundity, so it has quickly become the first of the four pests in China in recent years.
