What should I do if there are suddenly cockroaches in my computer desk at home? How to exterminate?

1. Measures to cure the root cause.

The environment is dirty and messy, and cockroaches are rampant. Therefore, doing a good job in sanitation and environmental control is a fundamental measure. To kill cockroaches indoors, we must first do a good job of sanitation and remove cockroach habitat conditions, and extensively carry out plugging holes and wiping cracks and "eight checks" activities to remove cockroach habitat egg sheaths and cockroach traces.

Cockroach traces refer to insect corpses, residual limbs, bodies, wings, molting, cockroach feces, empty egg sheaths, etc. "Eight checks" refer to: one check table, two check cabinets, three check chairs, four check (sewer mouth), five check pools (washing pools), six check cases (food processing boards), seven check seams, eight check piles (coal piles, firewood piles, sundries piles).

Cockroaches like to burrow and hide in the cracks. Taking advantage of the living habit of pests, you can choose putty, cement or silicone to plug the caulking gaps and burrows, so that cockroaches have no place to hide. For those kitchens with severely damaged interior walls and outdated furniture, in order to eradicate cockroaches, it is necessary to completely repair the house and replace the furniture.

2. Reasonable spraying to kill cockroaches.

Cockroaches often drill cracks and holes to inhabit and hide, so when using a sprayer to spray, be sure to spray for cracks, holes, corners, and around them, so that the spraying effect is good and the drug is saved. Cockroaches are reptiles, spray cockroaches should not be sprayed into the space, and they do not have to be masks, spray on all four walls.

3. The trick of putting cockroach poison bait.

Putting poison bait is a common and simple way to kill cockroaches, but to use it properly, the trick is to "small amount, more points, and wide area", that is, to inject more poison points in a room, and the amount of medicine on each point is less, and the distribution area should be wider. In this way, cockroaches can crawl out of the habitat and eat the poisonous bait, and the killing effect is obvious. In order to prevent the poison bait from failing when damp, it is advisable to put the erbium poison particles in the cap of the bottle.

Use insecticide-containing chalk to draw on cockroach sites. Around the crevices, holes and corners where cockroaches inhabit and where they often move, use medicine to draw circles or the word "well" so that cockroaches are poisoned by scribbled powder when they enter and exit the movement. The scribing should not be too thin, it should be a thick line of 2-3 cm.

4. When moving to a new home, don't forget to exterminate cockroaches.

In recent years, urban buildings have sprung up and residents have moved into new homes. Warning to the public: When you move, please be sure to remove the cockroaches and their egg sheaths hidden in old furniture, clothes, books, cardboard boxes, and wooden boxes, otherwise, cockroaches will soon appear in the new house.

Cockroaches do not fly, they rely on vehicles and goods such as luggage, parcels, and furniture to spread, causing regional and even international spread.

In addition, there are: 1. Fresh cucumbers repel cockroaches. Put fresh cucumbers in the pantry so that cockroaches won't get close to the pantry. After two or three days of fresh cucumbers, cut them open and continue to emit a cucumber flavor, which can also effectively repel cockroaches.

2. Fresh peach leaves repel cockroaches. Put the freshly picked peach leaves in a place where cockroaches often haunt, and cockroaches will avoid the smell of peach leaves when they smell them.

3. Onions repel cockroaches. If you put a plate of sliced onions indoors, the cockroaches will flee immediately when they smell it, and it can also delay the smell of other foods in the room.

It is best to go to the supermarket and buy some cockroach bait, insecticides can only kill the cockroaches found, and bait is the long-term solution.

The methods and drugs for killing cockroaches include sticky cockroach paper sticky trapping, fumigation to kill cockroaches, powder contact killing, poisonous bait trapping (bait and glue bait), and drugs.

The types and products are aerosols, powders, baits, sprays, fumigants, cockroach houses and other insecticides.

Among them, the use of aerosols, powders, sprays, fumigants and other cockroach killing characteristics is that the effect is fast, the disadvantage is that cockroaches flee and avoid when killing cockroaches, choking people, short efficacy, cockroaches rebound quickly, easy to produce resistance; When exterminating cockroaches, it is necessary to close the doors and windows, evacuate personnel, and open the windows for ventilation after the cockroaches are exterminated to prevent people and pets from being poisoned and polluting the indoor living environment.

Therefore, indoor medicine should be based on environmentally friendly insecticides that do not contain chemical pesticides to protect people's health. At the same time, it is also necessary to choose bait (glue bait) that is not volatile, has long-lasting efficacy and high killing rate for cockroach control.

Find the cause, address the root cause, and prevent it.

Cockroaches prefer dark, damp places, and usually prefer to climb along the corners of walls, as long as there is food and grease, they will come from far and wide. Cockroaches don't come to the house and don't leave right away.

If the cockroach thinks that the environment here is good, it is very likely to choose to start a family and have children here, so to deal with the cockroach to its nest, such as the drawer, it is not enough to clean up the inside, to pull out the whole drawer, because there may be many cockroach eggs hidden in the back, is giving birth to cockroach babies.

Prevention and control measures

1. Always keep hidden places clean. To find the source of the insects, you can suddenly turn on the lights at night when the cockroaches are active, observe where the cockroaches are, and where they are going, find their hiding places and then eliminate them.

2. For sheltered places, Keswei can be used in places where cockroaches often come and go.

3. Apply paper tendons and lime (500 grams of paper tendons plus 50 kg of lime, and then add water to mix) paint to all the gaps, and plug the gaps.

4. If there are too many cockroaches in the warehouse, workshop or indoors, and the harm is serious, it can be eliminated by sulfur or aluminum phosphide fumigation.

Cockroaches in laptops require professional maintenance personnel to be responsible for disassembling parts to avoid damage to the computer.

What can be done is to cut off the power supply to avoid causing greater harm because the power is not cut off in time.

Do not spray liquid drugs into the computer, which is easy to cause a short circuit; Ask a professional maintenance personnel to be responsible for disassembling the parts to avoid damage to the computer.

Don't try to disassemble your laptop yourself, as laptops are more sophisticated than desktops, and different brands disassemble and assemble them differently. Otherwise, it will have an immeasurable impact on the computer. Do not use insecticides or slap the laptop with your hands to drive out the cockroaches, the former is easy to cause a short circuit and burn the motherboard, and the latter is a taboo in the daily maintenance of the laptop - impact.

Cleanliness: Cockroaches love damp and messy places, so keep your home clean and hygienic. Regularly clean the trash cans, wipe down the tables, wash the dishes, sweep the floor, etc., so that they are left without food and hiding places.

Plugging entrances: Blocking cockroach entrances as much as possible, including repairing water leaks, plugging cracks and gaps, installing sealed doors and windows, etc.

Use of agents: There are many types of cockroach agents available in the market, such as sprays, baits, powders, etc. When using, you need to pay attention to the use of the stool according to the instructions, and avoid contact with the area where the medicine or edible medicine is located.

Use a gooey board: Place the gooy board where it is likely to hide and wait for the cockroaches to get caught. This method is relatively safe and does not cause harm to humans and pets.

Hire a professional pest control company: If none of the above methods work, or if there are a lot of cockroaches, you can ask a professional pest control company to get rid of them. They will use more professional methods and tools to ensure that the cockroaches are completely eradicated and that they prevent the re-breeding of the cockroaches.

Removing cardboard from the home, cleaning up food debris at home, and putting in anti-cockroach drugs can all effectively solve cockroaches.

1. Cockroach medicine: "Cockroach bait", which is a trick to eliminate cockroaches, because the product can not only effectively kill cockroaches and eggs, but also attract cockroaches to take the initiative with the help of attractant factors, so that cockroaches can throw themselves into the net to achieve the effect of a nest. Moreover, the product is almost non-toxic to people, so you can use it with confidence.

2. Sanitation and cleaning: The indoor hygiene must be maintained to avoid dirty and messy situations.

3. Orange peel: After putting the orange peel in the sun, it can become a good helper to drive cockroaches away.

Don't shoot cockroaches when you see them, in fact, the eggs of cockroaches may be preserved and many small cockroaches will develop, and cockroaches may also come into contact with parasites.

It is recommended that it is best to take drugs to kill cockroaches or cockroach house to kill cockroaches. It is best to disinfect the dwelling after killing the cockroaches.

Picking down cockroaches with a nuclear smile is the most effective way to kill cockroaches:

1. Buy drugs for poisonous cockroaches and place them in places that are often haunted:

Nowadays, there are a lot of cockroach medicines sold outside, and they can be bought everywhere. In fact, it can also be seen how widespread cockroaches are. This method is very quick and straightforward.

I remember the last time I bought it in the form of powder, (it seems that the current one is a small box that has already been made, and you can just put it on.) Take the paper and separate it, put it in various corners, corners, mainly along the wall, and the next day, you will find that there are corpses all over the ground, so that after a few days, you will find that there are no corpses, which means that it is basically cleaned up.

But this must be paid attention to, when cleaning every day, pay attention to hygiene, and the washing must be well cleaned and disinfected.

2. Use spray insecticides

This method is the fastest and most effective. Close the doors and windows, encounter the insecticide directly in the corner where the cockroaches are infested and hiding, and remember to wear a mask, this insecticide is still very uncomfortable and harmful to the human body when the door is closed. After touching, the person leaves, closes the doors and windows for a while, and then you can go to clean up.

Remember to ventilate for a period of time before going in, so as not to poison yourself and get dizzy.

3. Cockroach sticker:

Now in the market, in addition to buying drugs to kill cockroaches, there are also cockroach stickers, which I saw last time. If it is placed in a place where cockroaches often crawl, it will directly attract cockroaches, and then it will stick directly. However, I personally feel that this practice can't ** cockroaches, and can only be reduced to a certain extent.

However, it is not as harmful as drugs.

4. Eliminate dead corners in the home and clean up the hiding places of cockroaches

This method is the most environmentally friendly and natural. Do a good job of cleaning the home, and pay attention to the cleaning and disposal of garbage every day. At the same time, we must pay attention to the corners, door cracks or wall cracks placed in the seats, cabinets, etc., all clean up and seal the seal, let go of the release, in short, let it have no place, suitable for the room where the furniture is not too much, there is always a place to hide if there is too much furniture.

In this way, if the cockroaches have nothing to eat and no place to live, there will naturally be no cockroaches.

5. Place orange peels in cockroach hideouts to prevent and drive away cockroaches

The previous talk is about exterminating cockroaches, but there are no good habits and effective prevention and control methods, and there will be after a period of cleanup. Well, the best thing to do is clean, clean rooms and kitchens. At the same time, you can put the orange peel or grapefruit peel that you usually eat into the hiding place or action place of cockroaches, which can be a good way to prevent cockroaches, and also remove odors from the dead corners of the room.

But the fool is that you must remember to replace and clean it regularly, so as not to let it rot or become moldy and smelly, which will attract mosquitoes.

First, in places where cockroaches are frequent, stick some moisture-proof aluminum foil. Generally speaking, bathrooms and kitchens are where this insect often appears, especially in kitchens.

Second, it is to use cockroach medicine, many people will use cockroach medicine at will, or when they see cockroaches appearing, they will put cockroach medicine, which is actually wrong. We should grasp their dynamics before placing drugs to be able to play a good role.

Third, plug the source where cockroaches often appear.

Fourth, after finding cockroaches, even the corpses should be cleaned up in time. That's because cockroaches don't just eat food, they may also eat the corpses of their own companions.

How to eradicate cockroaches at home: clean up the environment and do a good job of cleaning and hygiene. The holes and gaps that can be plugged are plugged in time.

Cut off water and food sources. 1. Laundry detergent is a highly effective agent for trapping cockroaches, and its effect is even better than some chemical insecticides. Sprinkle laundry detergent in areas where cockroaches may be infested, and it will die after eating the laundry detergent.

2. Take a portion of borax and flour, a little sugar, mix well to make rice-sized balls, and sprinkle them in the place where it haunts, and the cockroaches will be poisoned to death after eating.

3. Hot soapy water to kill cockroaches, add a piece of soap to 4 liters of hot water, dissolve it and spray it directly on the cockroaches, which can effectively kill cockroaches.

4. Soda cockroach removal method, mix half of sugar and baking soda powder, put it in the cockroach infest, about 3 14 days later, the cockroaches will disappear.

5. Boric acid mopping and cockroach prevention method, after dissolving an appropriate amount of boric acid with hot water, wipe the floor with a mop or rag, after drying, white boric acid crystals will penetrate into the cracks of the floor, which can prevent cockroaches, ants, etc.

6. Orange and lemon peel cockroach prevention method, after drying or roasting the peel of orange and lemon, put it in various cabinets, which not only has the effect of flavor agent, but also has a certain anti-cockroach effect.

7. Mix a little borax with flour and add a few drops of sesame oil. Make a ball. Roll the medicine into a cylinder with paper and place the prepared medicine dough in the paper tube.

8. Take 1-2 canned bottles, put 3 tablespoons of sugar water, add half a bowl of boiling water to make it bait, and put the bottle in the place where the cockroaches are active.

9. Buy 100-150 grams of tung oil for cockroaches, heat and boil it into a viscous colloid, coat it around a 15 cm square board or cardboard, put greasy and fragrant food in the middle as bait, and cover other foods to prevent them from stealing food. When cockroaches are foraging, they can be stuck as long as they crawl to a place with tung oil.

10. Cockroaches are omnivorous insects, and they are resistant to hunger and thirst. When killing cockroaches at home, block the water source, turn off the faucet, wipe off the water traces, and scratch with a medicine pen or place poisonous bait around the base of the pool, urinal and refrigerator so that the cockroaches are exposed to poisoning when taking water and feeding.

11. Put fresh cucumbers in the pantry, and cockroaches will stay away.
