There are always a lot of cockroaches at home, big and small, and I have bought a lot of medicines b

There are many ways to find cockroaches at home, but they can't do it.

A month ago, a large cockroach was found at home, and more than a dozen were eliminated, but the big one was gone in the past two days, but I found a very small cockroach, and I also used cockroach medicine, is it ——— cockroaches are often killed, which can only play a role in easing and reducing, and cannot be completely solved, once and for all. Cockroach activities are too extensive, on the walls, in the sewers, and everywhere they have the chance. The kind of mosquito and cockroach killer spray in the cockroach supermarket ** is very effective.

The egg period of cockroaches is about 30 to 90 days, and the medication time should be more than 3 months, and the home should be kept clean. Cockroaches are humid animals, and try not to leave stagnant water in the kitchen. This can greatly reduce its population density, but it does not guarantee complete eradication. Hope to adopt.

Can't say that unless you can keep the cockroaches out and don't let them in.

The cockroaches are super fertile, put some medicine, and take a look.

I also feel this way, because of work reasons often change rooms, and then sometimes I find that there were no cockroaches in the room before, and after someone came to knock on the door to sell cockroach medicine, suddenly there were cockroaches!

To use cockroach medicine, to cut the grass and eradicate the roots, cockroaches have a strong reproductive ability, and they cannot be allowed to grow. The corpse of the large cockroach is to be cremated. And cockroaches are walking back and forth through some pipes, so there may be a lot of cockroaches all of a sudden.

Also buy some cockroach medicine, we haven't seen cockroaches in our bedroom since we used cockroach medicine, it's quite effective, anyway, there are cockroaches, just use medicine to get rid of it.

What should I do if I have cockroaches in my house? Teach you a trick to get rid of the "cockroach squad" at home

Clean (especially in small corners), keep the room well ventilated and keep it dry.

If you don't use medicine, then you can catch it yourself!

1. Artificial hunting

Under normal circumstances, when cleaning, it is necessary to look for cockroaches and their egg sheaths in their respective gaps and corners, especially in spring and autumn, to rummage through boxes and cabinets to search for cockroaches hiding in the cabinets. During the peak breeding period in summer, 1-2 hours after the night light goes out, suddenly enter the house, catch cockroaches with a fly swatter, and hit cockroaches when they see them.

2. Rinse with boiling water

There are a lot of cockroaches in the kitchen, and with boiling water and steam poured directly into every crevice, hole and corner, it is easy to scald the cockroaches and egg sheaths hidden inside, which is economical, frequent, and very effective.

3. Bottle trapping

Put a small slice of bread or other sweet food, or a spoonful of brown sugar into an empty can, smear the mouth of the bottle with some sesame oil, and use cardboard to separate the mouth of the bottle from the tabletop.

The main methods of environmental prevention and control are:

1. Do a good job of indoor and outdoor hygiene.

Places where cockroaches often inhabit and move should be cleaned and kept clean, garbage and sundries should be removed in a timely manner, sewers should be unblocked, and the drain should be sealed when not in use, and the garbage should be cleaned daily.

2. Eliminate the nest of cockroaches so that cockroaches have nowhere to hide.

Eliminate cockroach parasites, so that cockroaches have nowhere to hide, as we all know, cockroaches mostly hide in the hollows in the walls and furniture, the holes and hollows on the window cabinets that can breed cockroaches must be blocked, small holes are plugged with putty, cement, etc., large ones are nailed with wooden boards or iron sheets, and often turn over the items in the kitchen and utility room, and remove the egg sheaths and fecal residues in the cabinets and drawers.

3. Cut off food and water sources so that cockroaches have nothing to eat.

Cut off food and water sources, so that cockroaches can not eat food, all kinds of food can not be placed everywhere, cockroaches should be placed in the refrigerator, in a vegetable cabinet with screen doors or in a container with a lid, the stove, table, and ground should be kept clean, do not leave food residues, and clean up kitchen garbage in time.

4. Check all kinds of goods, including express parcels, etc., especially non-staple foods before bringing them indoors, and clean up the packaging boxes (boxes) in time.

Find a drink, make a funnel with barbed wire, kill the mouth of the bottle, make the small mouth of the funnel into the shape of a fence, put it horizontally after it is done, and tiptoe up at the end of the bottle to make the mouth of the funnel hit the ground, and you can also put some food in it to attract cockroaches.

Physical methods can't effectively kill cockroaches, you can only see one dozen one, it is also called Xiaoqiang, how many can you fight?

If you don't want to use insecticides, on the one hand, it is necessary to keep the home dry and hygienic, and on the other hand, you should exercise your quick reaction ability, holding a fly swatter or foot board, and pat one at a time.

The small cockroach is a German cockroach, it is more difficult to exterminate, the physical method is estimated to be no, you can use a safe and non-toxic clean soldier to kill the cockroach bait or the gold thick to kill the cockroach bait (golden yellow syringe), the small cockroach is effective, the medicine is not harmful to people, and the cockroach can be exterminated in a few days.

The small cockroach is called the German cockroach, and the name has the word Germany, so it is said to be imported, but it was first discovered by the Germans, and the small cockroach is particularly difficult to exterminate. It is recommended that you use cockroach medicine that has a special effect on small cockroaches:

1. Clean soldiers kill cockroach bait.

2. Gold thick cockroach bait (golden syringe).

Remember to buy ** to kill, and carefully distribute the medicine, if the medicine is not good, the effect of killing cockroaches is not ideal.

Use cucumbers and onions to drive it away, because cockroaches are afraid of these two things.

You can use electric mosquito swatting, you can eliminate them without medication, the best of both worlds!

Physically, you have to turn on the lights, because cockroaches are protected from light.

I was tortured by cockroaches, that is the German Xiaolian, more than half a year, every day in the middle of the night up to fight cockroaches, scalded with boiling water, smoked onions, a lot of soil methods do not work, after using insecticides, at first I felt that there was no more, and then the scope of cockroach activities has expanded a lot, because cockroaches make me sleep all day long, because there are children at home, so I dare not use drugs indiscriminately, watching cockroaches crawl around, disgusting to death, the heart of selling the house has, and then a friend recommended to me Killing cockroach ointment in** The 22 yuan one I bought is a kind of ointment, squeezed on a plastic board, placed in a place infested by cockroaches, used for about a week, the cockroaches are gone unconsciously, it is amazing, there is no taste at all, and finally this nasty cockroach is exterminated, and now there are no cockroaches for four months, it is very quiet, you can also try it, I hope it can help you!

Yes, cockroaches are particularly strong in their ability to reproduce, cockroaches are reproductive, male cockroaches that have been maturing can produce 14 to 40 eggs in a week or twoThis kind of egg generally hatches between 20 and 40 degrees, but the higher the temperature, the faster it hatches, and it takes 20 to 30 days at a constant temperature.

But there are up to three months, in general, a cockroach can produce tens of thousands of cockroaches in a year, and the vitality of cockroaches is tenacious, even in a difficult environment, it can be produced. Just one cockroach can produce so many eggs, which is the fundamental reason why cockroaches in the home can never be eradicated.

Ways to control cockroaches:

To get rid of cockroaches, the first thing to do is to ensure environmental hygiene, clean up in a timely manner, including toilets and sewers, and clean up garbage. In order to prevent cockroach breeding, there is no need to leave sanitary dead corners in the home, food in the kitchen should not be left in the open air, and water should not be left indoors to block the gaps. It should be double-checked, and even an old computer case should not be placed.

The best thing to do to live in a building is to keep cockroaches hidden.

Any slit of 1 6 mm is a shelter for cockroaches. A cockroach nest will be built in place of paper bags, boxes, and corrugated paper. Some people pile cardboard boxes with books, newspapers, and magazines next to the refrigerator.

A warm and humid refrigerator is a breeding ground for cockroaches. These cartons become the best breathing space for cockroaches when they are active.

Cockroach nests are often hidden behind operating rooms, laundry rooms, heating boxes, televisions, computers, refrigerators, kitchens, and sewer pipes. In order to completely eradicate cockroaches, we must find the nest of cockroaches and destroy the cockroach eggs. Did you know that an ordinary cockroach can breed tens of thousands in half a year?

Possible. But if you find a big cockroach in your house, then there must be a lot of cockroaches in your house... Cockroaches have a strong reproductive ability, and a pair of cockroaches can breed hundreds of small cockroaches. Spray some insecticide

It is possible to replace it with another cockroach medicine. In the case of small cockroaches with cockroach medicine, it is generally because the cockroach has become resistant to cockroach medicine, and other drugs can be replaced at this time.

It is recommended to use dinotefuran cockroach drugs, and the proportion of ingredients is a little better.

Dinotefuran is a nicotinic insecticide developed by Mitsui Corporation of Japan. The chemical structure is very different from that of existing nicotinoid pesticides. It has the following features:

1. Safety. Dinotefuran is very safe for mammals, and its acute oral LD50 for mice is about 2500mg kg.

In other words, a 10kg pet will be fatal if it consumes about 25g of dinotefuran at a time. The dinotefuran content of cockroach medicine is equivalent to eating 5kg of cockroach medicine. In fact, dinotefuran cockroach medicine is less toxic than table salt.

Therefore, dinotefuran cockroach medicine is generally safe for cats, dogs and people, and pets at home can also be used with confidence.

2. Low resistance of cockroaches.

Dinotefuran, as a third-generation nicotinoid insecticide, has no cross-resistance with other nicotinoid insecticides. At present, it has excellent effect on the control of cockroaches, and there are almost no reports of drug resistance.

3. It has high insecticidal activity at low doses.

Cockroaches have a strong ability to reproduce, which requires cockroach medicine to have the ability to infect and kill.

The current cockroach medicine will take advantage of the characteristics of cockroaches eating the corpses and feces of their companions, and after the cockroaches eat the medicine, they will not die immediately, but after returning to the nest and dying, they will poison and eat the cockroaches that eat their corpses again.

This requires that the compounds of the cockroach medicine have high insecticidal activity at low doses, after all, the concentration of the cockroach medicine will be greatly reduced when it enters the cockroach's body. In order for cockroaches that eat their carcasses and feces to be killed, the compound needs to have high insecticidal activity at low doses.

Many people's homes are actually very clean, but cockroaches are occasionally found, which is actually a warning signal, and we must pay attention to it.

1. Bait drug: There is a "powerful cockroach bait" that can attract cockroaches to eat actively with the attractant factor, and then rely on the excellent effect of the cockroaches at home to achieve the effect of eliminating the eggs together.

2. Boric acid: Boric acid can block the stomach of cockroaches, causing cockroaches to starve to death because they cannot eat.

3. Boiling water: Boiled water can inactivate cockroaches by virtue of high temperature.

To eradicate cockroaches, we must first ensure environmental hygiene, clean them in time, including toilets and sewers, and clean up garbage in time. Do not leave sanitary dead corners in the home, do not place food in the open air in the kitchen, do not leave stagnant water in the home, and plug the cracks and holes in time, so as to prevent cockroach breeding. It should be carefully inspected, even the old computer case.

It is best for the whole building to act in unison, so that the cockroaches have nowhere to hide.
