What if there are cockroaches in the bathroom?

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. Move the articles and furniture that roaches inhabit to the place below -5- 10 for 30 minutes, and the 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.

Chemical control

Chemical spraying technology, when spraying chemicals, close doors and windows and exhaust facilities of electric fans. 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.

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, wind troughs 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.
