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 the stove and the sink.

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.

Cockroaches are diurnal and nocturnal, showing a distinct circadian rhythm. It has been observed that the German cockroach starts to be active at 19 o'clock, with a peak of activity from 21 to 22 o'clock, a small peak at 2 o'clock in the next morning, and a disappearance at 5 o'clock. The black-breasted cockroach starts its activity at 7 p.m., peaks at 8 p.m., and has two smaller peaks at 23 p.m. and 2 a.m. the next morning, and ends at 4 a.m.

It has been observed that the activity of the American cockroach in the 12-hour alternating environment of day and night can be divided into six periods.

Period 1: Activity levels begin to rise before the darkness begins.

Phase 2: After the darkness begins, there is a noticeable increase in activity.

Phase 3: Peak period, lasting 2-3 hours.

Period 4: Sudden drop in activity levels.

Period 5: During the second half of the darkness, activity remains low.

Period 6: 5 hours after dawn, either still have a low level of activity, or be completely rested.

In addition, although the German cockroach is mainly a nocturnal insect, turning on the lights at night sometimes does not make them flee immediately, and even in bright lights or during the day, they can be seen crawling on the table, wall, etc.

The activity and reproduction of cockroaches, like other insects, are affected by temperature. Under normal circumstances, the seasonal growth and decline of cockroaches is a change in the number of populations or communities that manifest themselves in response to changes in temperature.

Cockroaches are omnivorous and possess what scientists call "non-specialized" mouthparts. This allows them to live around humans and easily find food in food waste. Spilled food, garbage, and sewage can attract cockroaches, and they can even eat adhesives from books and even pastes from stamps.

Although they do not bite humans, medical entomologists have found that they feed on human fingernails, eyelashes, hair, **, calluses on hands and feet, and even food scraps on the faces of sleeping people.

The feet of cockroaches secrete oil in the micron diameter (minus 6th power of 10), and they can climb up and down smoothly by the capillary phenomenon generated by the surface tension of the grease, so they can climb walls without falling.

Eat. Eat. Crawl everywhere, crawl at night, crawl in corners, crawl in wet places, then reproduce and multiply, and then continue to eat and eat, crawl and crawl, and scare people everywhere.

Habitats vary from species to species. German cockroaches are mostly found in various crevices, such as around pipes, in the cracks in walls, wainscoting, etc., and in the cracks between floors. The American cockroach also likes to inhabit large holes, prefers humid and hot environments, such as brewery fermentation workshops, soy product processing plants, etc., and often lives in groups in wells, sewers, basements, etc.

Black-breasted cockroaches are mostly found in the corners of bowls, cabinets, tables and sinks.

In winter, they tend to live in kitchens, close to heat sources such as stoves and radiators. In the middle of summer, when the kitchen temperature is too high, they disperse and migrate to other places, so the density of cockroaches in the kitchen decreases, but the distribution increases.

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.
