The cockroaches have been exterminated in the summer, and will there still be cockroaches in the win

In summer, if the indoor cockroaches are eliminated, there is generally no winter, and in the cold winter, cockroaches have little activity, and there will be less reproduction, and they are generally in places with higher storage temperatures.

Cockroaches like heat and are afraid of cold, cockroaches are killed in summer, they will not appear in winter, and there will be the year after tomorrow, it is difficult to get rid of them, the most effective way to deal with them, clean up the house, dry the ground, and the cockroaches will disappear from your house forever.

There will be, because the house will be hot in winter, and it is better to kill cockroaches in winter, and there will be no in summer.

Comprehensively analyze how families use cockroach exterminators to kill cockroaches completely.

1. Drug to kill adult insects: Use long-term insecticides to spray cockroaches in places where they live or often move, so that they are poisoned and die in contact with the drug surface. Spray on cockroach habitats and crevices.

When spraying, follow the principle of outside to inside, top to bottom. Close the doors and windows, open the cabinet door, open the drawer, spray a circle of about 20 cm of barrier medicine belt on the periphery, and then spray the gaps, holes, and corners, and be sure to spray enough moisture. After spraying, it should be turned off for 1 hour, which has a good killing effect on cockroaches.

Be sure to pay attention to safety when spraying. The pesticide can be applied again at intervals of 1 to 2 months.

However, all kinds of insecticides and cockroach killers sold on the market can be divided into three levels according to their toxicity: highly toxic, poisonous and low-toxic. Even low-toxicity insecticides and cockroach killers are more toxic to humans and animals, and highly toxic insecticides are even more harmful. There is information to prove that for example, a person with a body weight of 60 kg may be poisoned and die as long as the oral gram or ** absorption gram is adopted, and the chronic toxicity of pesticides to humans can be carcinogenic and teratogenic.

Therefore, consumers should be highly vigilant about the use of insecticides and cockroach killers, and do not think that everything will be fine without acute poisoning symptoms such as dizziness and nausea at that time.

In addition, taking the currently widely used sanitary insecticides cockroachicides as an example, most of them use the world's recognized and safe deltamethrin as an active ingredient for insecticide, which has been confirmed by relevant expert tests that it is also significantly toxic to the nervous system of the body, and long-term, regular contact will cause nerve paralysis, sensory nerve abnormalities and dizziness and headache and other neurological symptoms. The insecticides and cockroach killers that belong to insecticidal components such as organophosphorus, organochlorine and carbamate are more toxic to humans and animals. Not only that, there is now a class of insecticidal aerosol cockroach killers (commonly known as insecticidal water) and early emulsifiable concentrate, etc., which generally use benzene and its homologues with high toxicity as solutions, and long-term exposure to these additives will damage the hematopoietic system and even have the potential danger of inducing leukemia.

2. Biological cockroach killer bait: The two most effective cockroach killer baits on the market are Xiaotaijian cockroach bait and Virulence Island cockroach bait. These two cockroach killers are pure biological agents, do not contain any chemical pesticides, are non-toxic and pollution-free, and ensure the safety and health of people and the environment.

Cockroaches have been wiped out in the summer, and those that have not been extinct still exist (including the young cockroaches that have been transformed from insect eggs), but the temperature is low in winter, and they rarely come out to feed.

The cockroaches have been exterminated in the summer, and the cockroaches will still be there in the winter, but there are fewer activities in the winter.

Cockroaches like heat and fear cold, and in winter it is not that there is none, but that there is less activity. It's mostly concentrated in places with higher temperatures, such as behind the heater, and there are basically no activities, so you rarely see it. In fact, this is a good time to get rid of them.

Yes, because there are still cockroach eggs that have not been destroyed, so keep the room clean.

As long as the cockroaches are completely eliminated, and the neighbors also eliminate the cockroaches at the same time. Then there will be no more cockroaches in a year or two.

It depends on how closed your room is, and whether the neighbor's house is still there, and if so, it is easy to run to your house again.

Therefore, it is best to exterminate cockroaches at the same time, completely eliminate them to prevent cockroaches from running back and forth.

See if the interior is clean and if you've cleaned it at the time. If not cleaned up. There will also be crevices and toilets.

It is best to sprinkle some cockroach medicine on the place where cockroaches are frequented, because the cockroach is very fertile and will appear if its eggs are not killed.

Cockroaches like to be in warm and humid places, and in winter they may hide in places such as the heating or kitchen, such as small cockroaches may also be inside the wifi router.

Cockroaches don't disappear in winter, they hide. In winter, the temperature drops, and when the temperature drops to a certain level, cockroaches will feel cold and find a warm place to hide. Most of the warm places in winter are relatively hidden, and generally we rarely go to check them, and cockroaches hide in these places and do not come out to move.

So, in the winter, we will feel that the cockroaches are gone, and there are no cockroaches.

In fact, the cockroaches are gone in winter, and it is relatively simple to find them, just check the warm places in your home. For example: the fan heat vent on the back of the refrigerator, the heat vent of the induction cooker, the router fan heat vent, etc.

Generally, electrical appliances that have been energized for a long time will generate heat, and this heat will form a heat source, and cockroaches like to hide in these places in winter.

Ways to get rid of cockroaches.

1. Use sticky cockroach paper to stick one by one, which is very accurate and effective. Don't step on it, if you step on it, it will release a large number of germs in the cockroach's body.

2. Use a sugar water bottle to catch cockroaches, take 1 to 2 canned food bottles, put 3 tablespoons of sugar water, and add half a bowl of boiling water to rinse it, as a bait. Put the bottle in the place where the cockroaches are active, once the cockroaches smell the sweetness, they will crawl into the "trap" of the canned bottle, which is simple and easy.

3. Hot soapy water to kill cockroaches, put the soap in 4 liters of hot water, and then spray it directly on the cockroach after it is dissolved, which can effectively kill cockroaches.

There will be cockroaches in winter. Cockroaches hide in dark and warm corners in the winter and come out to feed at night, especially in air-conditioned rooms, which are no different from summer and autumn.

Cockroaches like warmth and cold, and may even freeze to death in sub-zero conditions. For the weather in the south, the temperature in winter is a few degrees to more than ten degrees, and there are few extremely cold conditions, so cockroaches can still survive normally. And in the north, because there is heating in the room, so in fact, it is not the southern region.

Or the northern region.

Cockroaches can still be found indoors in winter. It's just that because of the cold weather in winter, the cockroach reproduction rate slows down, in this case, the cockroaches will look for a warm place to move, so that the range of cockroach activities is also relatively concentrated, and this time is also to exterminate cockroaches.

The best timing.

Cockroaches like darkness and fear of light, like to lie in the day and come out at night, and can be seen occasionally during the day. After dusk, they begin to crawl out and forage for food, and return to their nests in the morning. The temperature is most active at 24 32 and can be active at 0. In the tropics.

Cockroaches can reproduce and move throughout the four seasons.

In the northern region, there is a heating equipment in the indoor room in winter, the temperature is suitable, and cockroaches can move and breed as usual. Most cockroaches are oviparous, and their eggs are arranged in an orderly manner in the egg sheath, which can resist the influence of a bad environment, and are not easy to be killed by agents, and larvae can hatch when conditions are suitable.

Summer sortie.

Details:Cockroaches i.e. cockroaches.

Cockroaches are commonly known as cockroaches. It is one of the oldest and most successful insect groups in the world. Cockroaches are commonly known as cockroaches. It is one of the oldest and most successful insect groups in the world.

Origin

Cockroaches and other insects originated in the Devonian period, and are saprophagophagoes that like to lie dormant and live in caves. It has withstood the test of extreme heat and cold, and has been widely distributed so far. Cockroaches are one of the oldest insects on the planet, having lived in the same era as ancient creatures such as dinosaurs, trilobites, and dunkles.

It was even more than 100 million years before the first dinosaur on land was born. According to fossil evidence, primitive cockroaches appeared on Earth about 400 million years ago in the Silurian period. The fossils of cockroaches that we have found or those found in coal and amber have become more and more resilient and have flourished to this day, widely distributed in all corners of the world.

It is worth mentioning that a cockroach that has been decapitated by humans can live for 9 days, and the cause of death after 9 days is excessive hunger and thirst.

Cockroaches are active all year round. Cockroaches prefer to choose warm, moist, abundant food and crevices to live, which are the 4 basic conditions they need to breed. All buildings where people live and live generally have these conditions, so cockroaches have become a sanitary pest that infests thousands of households.

Warmth and love tide is an important habit of cockroaches.

Cockroaches spend about 75% of their time at rest 24 hours a day. Cockroaches also have a habit of living in groups. It can often be found in a single habitat, always with a few or a few.

Ten or hundreds of them are clustered together, mainly due to the attraction of pheromones. Both adults and nymphs of cockroaches secrete an "aggregate pheromone" that is secreted by the rectal pad and excreted in the stool.

In places where cockroaches live, it is common to see brown fecal spots formed by their droppings, and the more feces there are, the more cockroaches gather. It can be seen that in the prevention and control of cockroaches, it is an important measure to do a good job in hygiene and remove cockroach traces. Water is more important for the survival of cockroaches than food.

Cockroaches are resistant to hunger but not thirst.

I think cockroaches like to decompose oily dirt. Cockroaches can easily grow in areas with water or humidity, and can occur in both summer and winter. There is no difference in time.

The room I live in is also quite annoying to have cockroaches all year round.

Summer! I have cockroaches alive on the 19th floor of my house. At 12 o'clock in the evening, the kitchen is full of cockroaches. I'm going to be scared to death!

Both summer and winter will have cockroaches that are extremely vigorous.

It had a broken head, and it could live for 15 days, and the cause of death was starvation.

As long as you keep your home clean and clean, don't leave food behind.

Then the number of cockroaches can be greatly reduced.

And cockroaches like humid environments, so they'll be seen in the gutters.

There will be more summers, and now that the overall global temperature has risen, there will be a small number of activities in winter.

Cockroaches don't come out in winter, cockroaches prefer dark, damp and warm places.

There will be unclean or damp places.

In the summer, but also in the winter.

Summer sortie. However, it is easy to appear if it is not clean.

Summary: No.

Below -3 degrees, it will take 17 consecutive hours for cockroaches to freeze to death and disappear. Water above 70 degrees can kill. Cockroaches, generally referred to as belonging to the "order of cockroaches."

The wings are flat, the forewings are leathery, the hindwings are membranous, and the fore and rear wings are basically the same size.

Cockroaches:

Most of them look similar, but a closer look reveals the difference. Current taxonomists classify cockroaches into about 6,000 species, of which about 50 are pests, such as the common Asian cockroach.

In addition, the American cockroach (American cockroach.

German cockroach (German cockroach.

Brown cockroaches and Australian.
