Why is there a spider web in someone's room, but not in someone's room?

Spiders like to live in an environment with a temperature of 25-35 degrees and a humidity of 35%-55%. Of course, this is most of the spiders we usually see, but there are also some lake spiders and water spiders, who live in coastal lakes and fresh water areas.

Then, we are likely to see cobwebs in places with suitable temperature and humidity, because spiders are always here. So personally, I think it's not just because people are alive and people are not. After all, my experience tells me that cobwebs may appear in both occupied rooms and unoccupied rooms, and spiders will patronize them. Under the same environmental conditions, the probability of occurrence is 50% each.

Of course, in addition to the environmental requirements of the room itself, let's solve the problem of this article. In fact, accurate incoming parts have the same other prerequisites, which can be explained by the principle of control variable method. The only variable is whether the room is occupied. Other conditions, such as temperature, humidity, room material and so on. In addition, we all know that spiders are afraid of light, so they will make webs in places with light and ventilation, because more insects will pass by in such places, and then more insects can be netted as food. If the two rooms have equal lighting, why on earth is there a spider web in the living room, but not in the living room?

The answer I give may only be for people who live in the room. Maybe people don't pay attention to hygiene, for example, they don't take out the garbage, don't tidy up the room, the kitchen is in a mess, there are many flowers and plants, but they don't have time to take care of them. Because of the owner of the room, there are many mosquitoes in this room, because the temperature is moderate and the environment is not dry, which is suitable for the life of spiders. In addition, mosquitoes, flies and flying insects are easy to get as spider food, so it is bound to attract many spiders to live here with you.

In another room, although the environmental conditions such as temperature and humidity are also suitable for spiders to live, there are no people to live in, there are no countless food sources, only endless dust, and the dust can't satisfy the spiders.

I think if you are a spider, you also know where to choose as your home.

Actually, this is easy to understand. Even if we don't understand it from the perspective of ordinary creatures, we humans are creatures who seek advantages and avoid disadvantages and often make choices. Yan Fu put forward "natural selection, survival of the fittest". Since human beings have developed to this point, I think they know the importance of choice better than spiders and other creatures. If you have studied a little economics, you will know that there is a theory called "benefit optimization" and "benefit maximization", and the typical statements of other disciplines will not be detailed here.

In short, under the premise of controlling variables, people's personal living habits, as the only variable, have become an important factor that makes the probability of cobwebs in the living room far greater than that in the unmanned room.
