Why you can’t kill spiders in an apartment and a house a sign

Curiosity prompts to look into the world of spiders. Modern life, as we know, would never be possible without their engineering experience. No doubt, these are charming little creatures!

Facts about spiders

Spiders, along with other insects and crustaceans, belong to the arthropod. Pajshaped divide this class with ticks and scorpions. Arachnids-as they are called, because a long time ago a little girl named Arachne defeated the Greek goddess Athena in the weaving competition. As a revenge, Athena turned her into a spider.

  • To date, more than 36,000 species of spiders have been identified.
  • They exist around the world, from Arctic to Everest. The only place where they cannot be found is Antarctic. Spiders live in nooks, on the bark of trees, in the forest, in the desert and even walk on the water.
  • As a rule, spiders live 1-2 years, although there are some types of tarantulas that live up to 20 years!
  • Many spiders eat insects, plants and even dead animals. They prefer to stay away from people.
  • Many spiders lead a night lifestyle. That is, they are most active at night.
  • It is best to watch spiders at a distance. It is interesting that in many houses, at least several dozen spiders live.
  • You can not kill spiders because they eat harmful insects! The average spider eats about 2000 insects in one year.
  • Spiders existed at least 150 million years before dinosaurs, according to fossils. Fossils, which are 380 million years old, indicate the existence of spiders.
  • Each spider makes silk threads

    Each spider makes silk, but not all spiders make a web. Those who make the web use tiny claws to walk without sticking.

    Spiders are used for:

  • creation of nests;
  • manufacturing loops for shutters closing the nest;
  • manufacturing bags for eggs;
  • Mummification of production.
  • If the spiders depart from the nest, they will leave the silk thread, and if they feel danger, they use the thread to return.

    Tiny filters in the back of their body produce liquid silk. When he comes into contact with the air, he hardens. Interestingly, some silk is sticky, while others are not.

    Small spiders also weave silk, and some use it to create a “balloon”. They climb high enough to catch the wind, and silk weaving takes them to another place.

    Some spiders are quite sociable and even “cooperate”, create cities from the web. They will connect individual networks that they make to one large network, sometimes large enough to cover the tree!
