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 mm is a shelter 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: For the egg sheath, it must be burned. 2: Rush into the sewer. )
E try to avoid using plywood or ceiling wall for furniture, and 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 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 a strict eating area, and do not eat any food except the restaurant 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 at home, dog friends must pay attention)
C. completely empty the trash can at least once a day. Tie the mouth of the garbage bag tightly before putting it.
D. don't eat in bed.
Prevent cockroaches from coming in
Pipes extending in all directions are the rapid transport system of 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.
In order to prevent cockroaches from entering the house, you must do:
Install screen doors and screens, or add fine nets to 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.
catch
At 8 ~ 12 pm, when cockroaches were active, they suddenly turned on the light to search and killed adults and nymphs. Before the cockroach breeding season, it can be killed for several nights continuously, 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 medicine:
All kinds of shops have all kinds of drugs to kill cockroaches, so I won't go into details. 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. (Drugs must use biological cockroach killing drugs that are environmentally friendly, effective and harmless to people, such as Xiao Taijian and Poison Island)
When applying pesticide, the food and water of cockroaches should be removed, because cockroaches are hungry and dry-resistant, especially pregnant female cockroaches with eggs, and they must have enough food and water, otherwise the egg sheath cannot hatch.
7. Dispose of cockroach carcasses
Wear gloves; 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 movement around them, which is as sensitive as hearing organs. So there was an instrument to drive away cockroaches like a mouse. Driving away will hurt the neighbors. Suggest elimination.
9. plant flowers to avoid cockroaches
Does planting flowers 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. Regular inspection
Anything you buy home or bring into the house, you'd better confirm it 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 natural enemy that can effectively control the pest has been found. In addition, it also has a unique high fertility, so it quickly ranked first among the four pests in China.
(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. Glue bait is an effective way 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.
The commonly used effective methods include throwing poisonous bait to kill cockroaches, spraying pesticides, smearing cockroach-killing chalk, dusting powder, spraying insecticidal smoke and so on. , according to the actual situation. In addition to chemical methods to kill pests, cockroaches can also be trapped and killed by physical methods such as sticking boxes and catching bottles. How to reasonably spray drugs to kill cockroaches?
Cockroaches often live and hide in crevices and holes, so when spraying drugs with a sprayer, they must be sprayed around crevices, holes and corners, so that the spraying effect is good and the drugs are saved. Cockroaches are reptiles. Don't spray them into the space and don't wear masks. Spray around.
The trick of throwing cockroach bait
Putting poison bait is a common and simple method to kill cockroaches, but if it is used properly, the trick is "less and more, wider", that is, there are many poison spots in a house, with less dosage and wide distribution. In this way, cockroaches can eat poison bait when they climb out of their habitat, and the killing effect is remarkable.
In order to prevent the poison bait from failing due to moisture, it is suggested that the poison bait particles be put into the bottle cap. Use chalk containing pesticides to draw pictures where cockroaches are active. In the crevices, holes and corners where cockroaches inhabit, and in places where cockroaches often move, the word "well" is used to smear powder marks on cockroaches when they go in and out or move to poison cockroaches. The drawn road should not be too thin, it should be a thick line of 2-3 cm.
