Beijing's multi -regional "noise"?Experts explained doubts-

"Such a big bug, scared me half of his life ..." "It seems like a cockroach!" ...

On August 20, a number of Beijing citizens reported that China greedy steps appeared in their homes.

What type of insect is this? How should we deal with it?

At first glance, this kind of bug looks like a cockroach, with a black shell, with two tentacles above the head and three pairs of feet.

Liang Hongbin, an associate researcher at the Institute of Animal Research of the Chinese Academy of Sciences, told the Beijing Daily (ID: bepming_daily), "Greated step armor is a large genus, and it is generally a insect that is beneficial to humans." Greeding step armor is mainly based on the tender seeds and softness of the plants and the softness of the plants. The small insects are food, whether it is to people or the environment, there is no harm. "Greated sideline is also a natural enemy of many pests, such as mosquito, fly maggots, and bulb -winged pests. From this perspective, it can also be said that it is a pest."

But this insect is not completely beneficial to humans. "It is called greedy step armor because it is more greedy." Liang Hongbin said that experts had investigated in Inner Mongolia and northern Hebei and found that in Xiaomi's fast -mature grouting period, greedy steps would climb on the spikes to eat. It is very sensitive to light, and a beam of light on the grassland may attract thousands of greedy step armor.

Some experts also believe that the appearance of Chinese greedy steps in the community is not only a bad thing, but it means that the biodiversity of the city is relatively abundant and can provide sufficient food for greedy step armor.

To block the greedy steps, experts suggest that you can use the simplest way: if you turn off the unnecessary lights and close the window. Once there is a greedy step in the home, the citizens only need to sweep them out with a broom.
