What are spiders needed for in nature and how are they useful for humans?

Spiders are quite voracious. No spider will ever settle where there are no insects for it to catch and eat. Thus, if a lot of cobwebs and their owners suddenly appear in your apartment, you need to look for other tenants who serve as food for them, for example flies, midges. But you still need to get rid of spiders in the house because such a neighborhood is unsafe and scary.

Having settled in an apartment, such a “pet” first of all weaves a web, since it is with its help that the spider obtains food for itself. “Removing the web” is not a sufficient measure to get rid of these insects, since they are very hardy and patient, and will weave the web again by the next day. Most species of spiders live in nature. Only a few species are able to settle in a house or apartment.

What spiders live in houses?

House spiders love dry climates and warmth, so they can most often be found during the warm seasons of the year.

It’s quite normal for several species to coexist next to a person, so it’s worth thinking about how to get rid of spiders in an apartment . The most common ones include:

• The haymaker spider is also known by other names - the centipede or window spider. The body of this spider consists of a round or oval abdomen up to 1 cm in length and eight or six legs, which are the most noticeable part of the body, since their length often reaches 5 cm. The haymaker sets up special nets in the corners of his home for his prey. Various small insects, once trapped, begin to flutter and become even more entangled. While the spider guarding them injects poison with a paralyzing effect into the body of the victim and feeds on it, or leaves it for the future. In apartments, the haymaker likes to settle in dark corners and near windows, prefers to hang upside down. Seeing a large insect approaching, she tries to prevent it from getting into the web and begins to swing it.

• Gray and black house spiders are distinguished by much smaller bodies and legs. The total body length is generally 14 millimeters. These subspecies of house spiders weave their webs in the shape of a tube. Moreover, after catching a victim, they restore it. Thus, the entire network can be a rather complex system. In the web of black and gray house spiders, as a rule, a female remains to wait for the victim.

• Sometimes a hobo spider can enter an apartment through open windows or doors. They also have an elongated body and long legs. Their main difference is the absence of a web, which they simply do not need. The hobo spider rushes at the victim with a swift, sharp jump. Then it injects poison, devours the prey and migrates further, without staying in the apartment for long. The poison of hobo spiders that live in our climate is harmless to humans. However, in hot countries these spiders, or rather the secretion of their glands, are considered very dangerous for people and can lead to skin inflammation, as well as general poisoning.

Safe types

Safe species of spiders in Russia hunt insects, waiting for a long time for prey to fall into the net. Their bites are not dangerous for humans. These species live not only in nature; many live in courtyards and settle next to people in their homes.

Safe types of spiders in Russia include the following varieties:

• brownies;
• orb weavers;
• argiope;
• knitters.

House spiders

This species prefers outbuildings and human habitation for its habitat. Preys on moths, bedbugs, cockroaches and other small insects. In nature, dense grass or a crack in tree bark serves as housing. The variety spreads evenly throughout Russia.

External signs of a house spider:

• the body is colored yellow with a brown tint; there is a brown pattern on the surface of the back;
• spider size is from 0.7 to 1.2 cm, females are always larger;
• The legs are colored darker than the body, their length is approximately 2 times the size of the body.

Orb weaver in nature

The species lives in tree crowns, nets are placed between the branches, and the leaves are used to make shelter

Wheel-shaped traps immediately attract attention in a forest or garden. Sometimes round nets are placed under the eaves, in the window frames of abandoned houses

The poison is toxic to invertebrates and small vertebrates; it affects rats, rabbits, mice, but horses, dogs, guinea pigs and sheep do not react to the bite. The locust's muscles lock up after 35 minutes, and the frog stops moving within 15 minutes. When bitten, a person experiences mild pain, but the volume of injected poison remains safe.

Orb weavers have an increased appetite and eat up to 8 insects at one time. If there is prey that is unacceptable to it in the trap, then the owner breaks off the web around it and the insect falls. It does network cleaning in the same way.

Argiope arthropods

Arachnids of this species are not dangerous to large mammals and humans. Males are modest in size and rarely exceed 0.5 cm, while females grow up to 2.5−3 cm. The color of the back resembles a wasp due to its bright black and yellow stripes. Short hair grows on the chest and partly on the head. The long legs consist of several jointed sections and are black with pale yellow spots.

Argiopes are spiders of central Russia, because they prefer areas with a temperate climate. They are also found in the southern part of the Stavropol Territory. The bite of an arthropod is compared to that of a bee; spiders do not attack first and do not show aggression. A slight pain is felt at the site of the lesion, swelling appears, but everything returns to normal after 2-3 days.

Trudoviks knitters

The species is distributed throughout the Russian territory and is found more often than in other countries. They almost always prefer nature and do not live in buildings. For hunting, round nets with large rectangular cells are made. The observer sees that such a product is not suitable for fishing due to the rare threads, but it’s all about the specific victim that must fall into the net. Knitters hunt for long-legged mosquitoes, which are a favorite delicacy.

Knitter Description:

• the body has an oblong shape;
• long legs consist of segmented segments;
• many outgrowths are observed on the chelicerae;
• females are large, reaching 3 cm, but males are inferior in height.

The long body saves the knitter in case of danger. At a moment of anxiety, he stretches his legs along his body and in this position resembles a dry twig. If it is disturbed in this state, the spider quickly falls and quickly runs away.

The benefits and harms of spiders in the house

The most important benefit that spiders bring is the destruction of various harmful insects. Therefore, you may not need to think about how to get rid of spiders in a private house .
Spiders are quite voracious creatures. Every day one spider eats as much food as it weighs. For example, a crossbreed can catch and eat up to 500 insects in a net in one day, the vast majority of which are flies. Of course, everyone who is afraid of spiders is very afraid of being bitten.
However, only a few species of poisonous arachnids pose a danger to humans. Most of the spiders living near us are completely harmless. And the greatest harm they cause is their not very aesthetic appearance, as well as ugly cobwebs in the corners of the house. Everyone chooses for themselves a certain behavior in relation to these animals. Before you kill a little spider, be sure to remember that spiders are more friends than enemies for people. Perhaps it would be much easier to take him to a place that is safe for him and just let him go?

What are they needed for in nature?

Arachnids are the most common species of animals; they live everywhere. Found in the northernmost regions, near glaciers, many species have inhabited deserts. Spiders were not too lazy to climb mountain peaks; they were found even on the approaches to Everest.

The species diversity of arachnids allows them to colonize different territories. They live in the soil cover, on trees and in grass, take over animal burrows, and make their way into a person’s house.

By their feeding method, spiders are classified as predators. They do not chase prey like cats, they weave webs and patiently wait for the food to end up in the web. When considering the benefits spiders bring to wildlife, we must not forget that they themselves serve as food for other animals.

The food chain created by nature makes spiders not only a predator, but also prey that is also hunted. Lizards, birds, wasps, and small mammals feed on arachnids. The extermination of spiders during cultivation of farmland causes significant harm to those for whom they serve as food.

Arachnids, like all predators, regulate the number of species they feed on. They are entomophagous (insect eaters), protecting plants from attack by pests and their excessive spread. According to some studies, spiders eat more insects than all other species combined.

Arachnids protect forests from the invasion of small pests, because humans only care about agricultural land. Hanging trap nets catch insects and significantly reduce their numbers.

The venom of the majority of arachnids is dangerous only for insects and serves to kill them. Poisonous species, dangerous to humans and animals, live in tropical zones.

Folk sign - a spider in the house

According to the ancient beliefs of our ancestors, the well-known sign about a spider in the house means well-being and wealth. It is noticeable that regarding the question of why spiders appear, the signs of different nationalities have almost the same meaning, and, as a rule, are only positive.

Why do spiders appear?

If you've seen spiders in your home, you're probably wondering where they came from. Here are a few reasons for their appearance:

• In cold weather, spiders like to climb into warm houses, because they are very heat-loving insects.
• High humidity in the home. Have you noticed that spiders most often weave webs in the bathroom and kitchen? As a rule, these are the dampest places in the house.
• Spiders prefer to eat midges, flies and other small insects, so if there are a lot of them in your house, then spiders will definitely settle in your place.

Spiders are quite frequent guests in the house.
To get rid of them, you can first try such a well-known method as spring cleaning. Remove all cobwebs, not forgetting closets and pantries.

If you don't remove them, then within a few weeks there will be small spiders running around the house. It is also necessary to find all other insects that live in your apartment, since their presence forces spiders to remain in your home.

Fighting spiders - blocking the entrances

Spiders in the apartment most often appear due to our sloppiness. Poorly done repairs, cracks in the walls and floors, and the appearance of other insects. All this attracts spiders.

Special preventive measures

Spiders often begin to colonize not the house itself, but the space nearby. If there is a lot of garbage near the building, and there are fallen leaves on the floor, then these insects are happy to settle in such conditions. And from there they move to your home.

Spiders also love grassy thickets and bright flowers on verandas. For these animals this is food. You can make a shelter in their leaves. Thus, to answer the question of how to get rid of spiders in a private house , it is important to remove flowers from the windowsills, as well as clear the home of excess vegetation.

It is better not to leave lighting near the house at night. After all, light attracts flies, moths and other flying inhabitants. And this is food for spiders. You can switch to special gas-discharge lamps; their light is unattractive to cockroaches, butterflies and ants.

Arachnids do not harm humans. They try not to show themselves to people at all. But, alas, the rightful owners never like invaders, and if you have them, you can remove them in a couple of days.

Proven ways to get rid of spiders

How does a house spider hunt?

The house spider goes hunting mainly at night, when it is dark, and it can catch prey not only with a web, but also without it. The web of this spider does not have adhesive properties; it has a thick, dense layer.

When an insect hits the web, it begins to shake and vibration is created. The hunter quickly picks up the signal and approaches the prey, plunges his sharp jaws into it, injects poison and digestive juices that help liquefy the insides. The victim dies, and the spider carries it deep into the living tube. Digestive juices help liquefy the insides; when they are partially digested, the spider sucks out the contents, leaving an empty chitinous shell. On average, a house spider can catch about 10-12 insects per day. Of course, he won’t be able to eat them right away, so the hunter makes supplies.

Sometimes the victim manages to defeat the spider and survive. For example, ants, despite their small size, fight a spider, which quickly exhausts it. Tired, the hunter can go into the tube, as a result the ant remains alive and calmly leaves the web.

The house spider does not live long in one web, because the remains of the insects it has caught accumulate in it. On average, a spider changes its habitat every 2-3 weeks.

As already mentioned, a spider can hunt without a web. In this case, he stretches two signal threads in a certain area. When the victim clings to the thread, the spider catches up with it and attacks.

The diet of a spider in a human home includes fruit flies, large house flies and other household pests.

Despite the fact that spiders are unwelcome neighbors in an apartment or house, they provide people with a service: they reduce the number of insects in the home.

Why were arachnids created?

The importance of arachnids in nature and human life is quite great: they bring many benefits to people and at the same time can be carriers of dangerous diseases. Playing the role of predatory creatures, they kill insects, while at the same time being part of the food chain of various animals, birds, and aquatic inhabitants. In nature, they perform the work of creating a habitat for other creatures; for example, the process of soil formation cannot do without soil mites.

In agricultural activities, arachnids provide first aid in combating pests that spoil seedlings in the fields and in the forest belt. This is an important feature of the importance of arachnids in nature and human life. Sometimes special predator mites are placed in closed ground to conduct a biological rescue operation.

Traditional methods of fighting spiders.

Of course, when they find spiders in their home, people immediately think about how to get rid of them as quickly as possible. First, you should try safe methods based on folk recipes.

• Peppermint oil. The scent that many people love is very scary to spiders. You can plant mint in a pot and grow it as a houseplant, or you can use the oil to treat furniture, corners and cabinets. You can also soak cotton pads in a solution of oil and water and place them in the corners. Repeat the procedure twice a week. If the option with disks does not suit you, you can spray this solution in the same places. In addition to mint, you can use eucalyptus and tea tree oils. Be careful when using if your loved ones are allergic to these oils.
• Fir oil. The smell of coniferous trees always has a very negative effect on arthropod insects. Use the same as mint, treat the corners with a solution or place cotton pads soaked in such a solution. Spiders will hurry to escape from such a smell.
