Left out overnight there were no cockroaches in the house

Hello you placed the cockroach house, cockroach bait, but did not catch them, does it mean that there are no cockroaches in our house? This doesn't mean if there are cockroaches, how can you tell if there are cockroaches at home? 1. Because cockroaches are afraid of light during the day and will not come out, they can only pay attention to whether there are cockroaches at night.

The easiest places to spot cockroaches are in the kitchen and bathroom. Around 10 p.m., turn off the lights, quietly light a candle and other faint lights to the kitchen or bathroom to see if there are any cockroaches. Remember quietly.

2. Scrub the kitchen stove clean, and then look carefully in the morning to see if there are any small particles on it. If yes, it's cockroach. If not, maybe not.

3. Sprinkle a layer of flour evenly on the kitchen table, just sprinkle it locally, don't waste too much. Because cockroaches also like to eat starchy foods, then flour is the best choice, so as long as there are cockroaches, they will climb on them to eat and pull. Then in the morning, just white flour.

There are traces of cockroach legs or small black particles, there are cockroaches.

The cockroaches didn't enter the cockroach house all night because you didn't put the cockroach house with the attractant food, which can give off the smell that cockroaches like. So that the cockroaches will find the taste and enter the cockroach house, so that we can achieve the purpose of eliminating cockroaches

It should be gone, or not put in the right place, and put it back in the corner, kitchen, bathroom.

No bait, no cockroach medicine.

When the day dawned, the cockroaches were hidden.

There are several reasons why cockroaches appear at night in the kitchen:

1.Cockroaches are nocturnal insects, and they are active at night.

2.There is usually an abundance of food and water in the kitchen, which are basic needs for cockroaches to survive, so they are attracted to the kitchen.

3.Cockroaches are sensitive to light when they are nocturnal, so the light in the kitchen is relatively dim, making it easier for cockroaches to move around here.

4.The noise in the kitchen is relatively low, and it is a relatively quiet environment for cockroaches, which is more suitable for their activities.

5.If the hygiene of the kitchen is poor, then it is easier to attract cockroaches to come and feed.

6.The kitchen is usually a confined space, relatively warm and humid, and this environment is also more suitable for cockroaches to survive and breed.

To prevent cockroaches from moving around in the kitchen at night, you can take the following measures:

1.Keep your kitchen clean and hygienic by regularly cleaning up food scraps, garbage and grease stains to reduce cockroach food**.

2.Use equipment such as range hoods at night to reduce noise and light in the kitchen and reduce the frequency of cockroach activity.

3.Using insecticides, such as spray insecticides or cockroach houses, can effectively kill cockroaches and prevent them from multiplying in the kitchen.

4.Install airtight trash cans and food storage containers to reduce the chance of cockroaches coming into contact with food and water.

5.If the cockroach problem is serious, you can consider asking a professional pest control company to deal with it.

Please note that these methods may need to be done consistently to effectively control cockroach activity. At the same time, if you find that the number of cockroaches is large or cannot be handled, please contact a professional pest control company for help in time.

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. Generally, 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 completely inactive at 4. In the tropics.

Cockroaches can reproduce and move throughout the four seasons. Northern Regions.

In winter, there is a heating equipment in the room, 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 the environment, and are not easy to be killed by pesticides, and can hatch larvae when the conditions are suitable.

Cockroaches are nocturnal insects, and if the climate is mild and moderate, they can breed a nest of 40 to 50 per nest in ten days. Cockroaches mainly live in kitchens, in all the gaps between the cabinet and the wall, in the cracks in the wall, in the kitchen drain are its habitat, can spray insecticide on these places, plug their gaps, scalded with boiling water.

Cockroaches like to nest in dark and damp places, and they need to be able to find food easily, if there are no such conditions in the room, cockroaches generally do not appear.

Probably not, cockroaches live conditionally, like shade and have a place with food!

Yes, but it will give birth to countless offspring. Cockroaches are extremely reproductive, so it's best to buy some cockroach medicine to get rid of them early.

If there are cockroaches in the house, there will be cockroaches no matter how long you don't live in people. There are cockroaches at home, only by cleaning frequently, ventilating frequently, keeping the home ventilated, dry, hygienic and bright, supplemented by insecticides, cockroaches can not be extinguished, because cockroaches like a dark and humid environment, and long-term inhabitation will only make the environment darker and more damp, which is more conducive to cockroach breeding.

That's it resting,Cockroaches like darkness and fear light, and they come out at night. During the day, they are hidden in dark and dark places, such as indoor furniture, crevices in walls, caves and corners, and piles of debris.

During the day, they lie dormant and rest on the bench to talk, and at night, especially after the lights are turned off and people go to sleep, they go out to do activities, or forage for food, or seek a mate. As a result, about 75% of the 24-hour day is spent at rest.

Place of residence

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.

It is not difficult to find that whether it is in a restaurant, a home, a train or a ship, the kitchen is always the most invasive. Even in the kitchen, they generally like to live near stoves and sinks. Like the dark and afraid of light, day and night, this is also an important habit of cockroaches.

During the day, they are hidden in dark and dark places, such as indoor furniture, crevices in walls, caves and corners, and piles of debris.

At night, especially after the lights are turned off and people go to sleep, they go out to do activities, or forage for food, or seek a mate. As a result, about 75% of the 24-hour day is spent at rest. Cockroaches also have a habit of living in groups.

It is often possible to send a perch, always a few less, more than a few.

Ten or hundreds of them are clustered together, mainly due to the attraction of pheromones.

Both adults and larvae of cockroaches secrete limbs or a "aggregation 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.

When the American cockroach is only given dry food and no water, the female can only survive for 40 days, and the male can only survive for 27 days. Conversely, if there is no water to eat, the female can survive for 90 days and the male can survive for 43 days. When under harsh environmental conditions, when there is no food and no water, cockroaches will eat each other, eat big and small, strong eat weak, especially the insects that have just molted, can not move, the skin is tender, and it has become the prey of competing for food.

There are two reasons for this:

Clause. 1. From the perspective of the habits of cockroaches, cockroaches are insects that emerge at night during the day, which means that cockroaches hide and rest during the day and come out to move at night.

Clause. Second, only if there are a lot of cockroaches in the room, there will be a situation where there are many cockroaches coming out at night.

There are a lot of cockroaches at night, which means that there are a lot of cockroaches in the room, and you can use some cockroach medicine to get rid of cockroaches, and it is best to use them in the evening, because this time the cockroaches are just starting to come out.

The larval stage of cockroaches.

The larvae that have just hatched from the egg sheath are gathered around the egg sheath, which is white, and then the color gradually darkens and spreads out, and the larvae are similar in shape to adults, but the body is small, wingless, and the sexual organs are immature. The larvae develop slowly. It must undergo multiple molts to grow gradually, and the number of antennae and tail whiskers also increases with age.

After the last molt, the larvae grow wings and emerge into adults. Freshly molted larvae and newly emerged adults are also white and gradually darker in color, so that a species of cockroach can also change in a population according to environmental conditions. The larval stage is long, generally lasting about 30 450 days.

In the dead of night, the temperature and humidity are more suitable for cockroach activities, so you will see a lot when you get up in the middle of the night to go to the bathroom.
