If there are cockroaches in the house, should you turn on the lights at night?

Want.

Cockroaches are nocturnal animals.

Cockroaches are naturally very timid, as long as there is any movement, cockroaches will immediately hide, they will not come out when there are people during the day, only in the dead of night is their best time to move.

In addition, cockroaches are very afraid of seeing light, they like darkness and fear light, especially strong light, so they can only move freely at night. So at night, as soon as the lights are turned on, they will hide. Cockroaches like to come out at night, which is related to the habits of the cockroaches themselves.

Cockroach hazards.

Cockroaches carry bacteria all over their bodies, and food contaminated by cockroaches can cause severe gastroenteritis and food poisoning.

or dysentery. It is a carrier of infectious bacteria and viruses, because of the food everywhere, crawling, wide range of damage, miscellaneous food, can be in the garbage, toilets, washrooms, and food, if you eat the cockroach contaminated food may transmit diseases.

Therefore, the harm of cockroach-borne diseases cannot be ignored.

Cockroaches have the habit of eating, spitting, and excreting at the same time, and secrete odorous liquids, and in their activities, they can not only carry leprosy.

Mycobacteria, Yersinia pestis.

Shigella dysentery bacillus and more than 40 other pathogens.

It is also an important vector for the transmission of intestinal diseases and parasitic diseases, and its secretions and feces contain a variety of carcinogens.

Cockroaches will also crawl out to sleep with the lights on, which has more to do with whether the environment is quiet or not, of course, the light also has a partly effect, but there is still a relatively large possibility of cockroaches. Generally, after dusk, they begin to crawl out and forage for food, and return to their nests in the morning. Cockroaches are good at crawling, swimming, and can fly in times of crisis.

You will not die if you do not eat or drink for an extended period of time.

Cockroaches belong to photoapathic animals, theoretically if the strong light is turned on at night, the movement of cockroaches can be limited to a certain extent, just like cockroaches can rarely be seen out to forage during the day, but if they are irradiated for a long time, cockroaches will also patrol the dark corners to carry out activities after adaptation, so light is not a good way to kill cockroaches.

Cockroach control methods:

1. Use soapy water skillfully. Cockroaches hate the smell of soapy water, so they soak soap or transparent soap in water and sprinkle it in places where cockroaches often hang out, and the cockroaches will quickly flee and prevent cockroaches from recurring. This is an economical and practical way to put cockroaches, don't add too much water during the splashing process, just use more foam, don't make the house full of water.

2. Cut the onion or fresh cucumber into pieces and put it in the corner of the room or in a humid place. The smell of onions and fresh cucumbers can be unbearable for cockroaches, and they will not care. You can also put onions and the like in the pantry so that cockroaches don't dare to approach the cabinet.

3. Place poisonous bait to prevent cockroaches. Go to the pharmacy and buy some medicine for poisonous cockroaches, like boric acid or something. When putting it in, it is necessary to "have a small amount, many points, and a wide area", that is, there are more places to poison in a room, and the amount of drugs in each place is less, and the distribution area should be wider.

Afraid of light, but turning on the lights has no effect.

Cockroaches are a kind of insects that like darkness and are afraid of light, have an obvious diurnal and nocturnal activity rhythm, generally start to move at 17 o'clock in the evening, 21-22 o'clock for the peak of activity, appear at 2 o'clock in the next morning, disappear at 5 o'clock, but they are not afraid of the light, turn on the light at night, sometimes it will not make them run away immediately, some cockroach varieties even in bright lights or daytime, you can also see them crawling on the desktop, wall, etc., so sleeping at night and turning on the light does not work for cockroaches.

Cockroaches are indeed more afraid of light, so it is basically difficult to find cockroaches during the day, cockroaches will basically not be active during the day, they like to hide in some hidden places during the day, for example, cockroaches will hide in some wall gaps or some corner debris, so that they can avoid the sun, sleep peacefully in it, and wait until the dead of night at night, people are asleep and turn off the lights after the black cockroaches will run out, At this time, cockroaches are able to forage for food and mate, engaging in a variety of activities.

Cockroaches are not afraid of lights at night, especially in some homes with relatively low floors, if there are bows and arrows below, it is some catering enterprises, and cockroaches often appear at home.

Cockroaches are not afraid of lights, but they are afraid of people, and they will run as soon as you come by.

Turning on the lights does not really prevent cockroaches, and if you want to prevent cockroaches from coming out, the most effective way is to eliminate them, so that cockroaches will not come out.

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. At night, cockroaches only go out to hunt for food, or seek mates, especially after the lights are turned off and people are sleeping.

As a result, about 75% of the 24-hour day is spent at rest.

Although cockroaches are photoapathic and usually move in the dark, they can also be found at night in bright places. Therefore, turning on the lights at night may still attract the appearance of cockroaches. However, prolonged exposure to light may allow cockroaches to adapt and move in shady corners, so light is not a good way to kill cockroaches.

To effectively prevent the appearance of cockroaches, other measures can be taken, such as keeping the house clean, using adhesives or chemical insecticides, etc.

In fact, cockroaches will come out like cockroaches, cockroaches are nocturnal insects, and their activity ability at night is particularly strong, especially in the middle of the night, even if the lights are on, they will crawl out.
