The way to kill cockroaches

The most direct way is to spray pesticides, then find out the cockroach carcasses and dispose of them in time.

Keep it clean for a long time, and put mothballs in wardrobes and other places to avoid cockroach outbreaks.

Kill cockroaches

1. First of all, 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:

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.

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.

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.

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.
