Spiders appeared in the house: reasons and what to do about it

Spiders often live near humans. Arthropods appeared on the planet long before people and settled everywhere. In a house or apartment you can find about 10 varieties of eight-legged creatures. Not a single species is capable of causing significant harm to human health, except perhaps to frighten, sometimes very strongly.

According to statistics, 7% of the world's population suffers from arachnophobia - the fear of spiders. There are more such people than those who are afraid of weapons, cars and airplanes combined.

Why do spiders appear in a house or apartment?

Human housing provides many suitable corners for spiders. Spiders have adapted to live in different conditions, and a comfortable apartment is a much safer place than the conditions of a forest or city street. There are several reasons why spiders appear in the house.

Lots of clutter in the space and infrequent cleaning. The house spider does not need much space to weave its trapping web or cocoon and live there. If you regularly clean up, sweeping away cobwebs in the corners, then the animals will not have time to weave a new one.
Dampness. Leaking pipes, wet rags, and never-drying puddles attract spiders.
Availability of feed for arthropods. Spiders are predators that feed on other insects:
midges
mosquitoes;
cockroaches, etc.

Humidity

In order for these eight-legged arthropods to appear in a home, unsanitary conditions and an abundance of insect pests are necessary.

Why see a spider in the morning, during the day, in the evening, at night: a sign

Also pay attention to what time of day you noticed the insect, because this will also help you correctly interpret the sign.

Signs, interpretation:

A spider at dawn - portends a good, successful day, positive events, good deeds and well-being, making the right decisions.
A spider at noon is a sign that tells you about true love that you already have or that you are yet to meet.
A spider at sunset means that financial difficulties will soon overtake you: payments, debts, big expenses, losses.
A spider on a dark night tells you that in the near future you will be lucky enough to have a good income.
A spider in the light of the moon means profit, prosperity, a good long and happy life.

Is it good or bad?

On the one hand, if spiders appear in an apartment, they are capable of destroying the pests living there. On the other hand, the networks they weave, and the very sight of many-legged creatures, can please few people. In advanced cases, there can be so many cobwebs that the home takes on a neglected, uninhabited appearance.

Spider-Man is certainly more afraid of him than he is of them. Arthropods will never hunt or specifically attack people. The spider flees from large opponents.

Important! Any spider living in the house, regardless of size, can bite. All types of spiders inject venom. It is not capable of killing a person or pet because its concentration is very low, but spider toxins can cause itching and allergies, especially in young children, allergy sufferers and people with weakened immune systems.

Spider Body Size and Structure

The body size of an animal depends on its gender. An adult female grows up to twelve millimeters in length, a male up to eight millimeters. Taking into account the distance between the legs, this size increases to twenty millimeters.

Tarantula spider on a man's hand

A characteristic feature of this species is the brown marking that resembles a violin. It appears in mature individuals, but is sometimes noted in young spiders. The recluse spider has six eyes, unlike other arthropod species that have eight visual organs.

At rest, the animal’s paws, devoid of spines, are thin and long, evenly distributed on the sides. In case of danger, the front legs are pulled under the body, the side legs are raised, and the hind legs are straightened.

The paws and lower part of the body are uniformly colored, without spots or stripes. On the bends of the joints of the legs, pigmentation is lighter compared to the main one. The color of the animal's body depends on its habitat and environmental conditions, from brown and dark brown to completely black.

The abdominal cavity of the hermit beetle is covered with fine hairs that look like fur when viewed under a microscope.

Routes of entry into human habitation

If you analyze where the spiders in the apartment come from, you can note several options:

Spiders appear in the apartment through ventilation holes, cracks in window frames, and between floorboards. If your neighbors are doing renovations or poisoning insects, you can expect an invasion of all sorts of uninvited guests.
You can bring a spider (or an egg from which a spider will later hatch) on shoes, outerwear, or in a bag from the place where it lived. Often insects “move” to a warm apartment from shops, warehouses, attics, and basements.
Doors and windows that do not close tightly, cracks in the walls (in particular, behind the baseboards, where they are not visible) are a direct way for spiders to enter the house.

What types of spiders are there?

Spiders, represented by several species, live in the house with humans. Most often it is:

haymaker (also known as centipede or windowcutter);
black or gray;
tramp.

The harvester has a body with a round or oval abdomen, six or eight legs, which are its distinctive feature. The length of the window spider's legs reaches 5 cm. The centipede weaves complex, extensive webs that trap small insects. The spider guards the victim who falls into the web, and as soon as the active desire to escape makes her so entangled that she cannot move, she injects paralyzing poison into her.

In a house or apartment, the haymaker chooses places near windows or in dark corners, hanging mostly upside down. When large insects approach, the spider, guarding the web, tries to swing it as actively as possible.

Black or gray house spiders are noticeably smaller than harvest spiders. Their body length does not exceed 14 mm. The web of such spiders resembles a pipe in shape, which after each victim the arthropod returns to its original position, repairing damage. Most often, female gray and black spiders hunt for small insects in the house.

An interesting type of domestic arthropod is the vagrant. They can be distinguished by their elongated body and long legs. The main feature of spiders is the absence of webs. They don't need it for hunting. Vagrants attack their prey while jumping, instantly paralyze it with poison, and then actively eat it. Predators do not stay in one house for long.

For humans, the poison of tramps is not dangerous, given the characteristics of our climate. In countries with hot climates, spider venom can cause inflammation of the skin.

In addition to the arthropods listed above, other species may appear in the house, but this does not happen so often.

Favorite Habitats

Spiders in the house prefer to settle in secluded, safe corners.

Often arthropods can be seen between wooden window frames, under window sills, behind radiators.
On the balcony, especially if it is used as a place to store necessary and not so necessary things.
A spider can live in the bathroom - in inaccessible crevices behind pipes and plumbing.
Dark basements, closets, and attics are the usual habitat of spiders.
Some spiders prefer to place catching nets on indoor plants or in pots.

Folk signs

Whether a meeting with a spider will be favorable or not is determined by environmental conditions, time of year or day, movement along the web, position and shape. You can listen to these signs, or you can ignore them. Although why, if superstitions, as a rule, bring positive news.

Let's remember the signs about the consequences of meeting spiders:

found on your head - get a big sum of money that you don’t expect;
to see in the morning means good luck for today, at noon (when the sun is at its zenith) - wait for the beginning of a great love story;
a spider hanging on a thread hangs in front of your face - an unexpected conversation with a person you haven’t seen for ten years;
appeared on the bathroom wall - to quick changes;
a spider hanging over the dinner plates means they are talking behind your back or eavesdropping;
a catching net over the bed - discord or betrayal (This sign will lose its meaning if you simply clean up, check the corners in the bedroom, remove traces of cobwebs from the ceiling, and send the spiders into the yard.);
if the spider moves upward on the web, expect a promotion, advancement in work matters.

What determines the number of spiders at home?

If you do nothing, then one fine (or rather not so fine) day there will be a lot, a lot of spiders in the house. Arthropods at home can live for many years and reproduce well. Sometimes you can see newborn spiders leaving the clutch. Having hatched from the egg, small spiders are immediately capable of independent life and scatter away from the “parental” nest. Each spider weaves a new web, grows, and upon reaching sexual maturity, increases the number of tenants. So after a certain period of time there will be a lot of spiders in the apartment.

Attention! To lay eggs, the female often chooses a quiet place where the spiders will not be in danger before hatching:

in cracks behind furniture, in the corners of cabinets, chests of drawers, under the bed;
behind the toilet or sink, where people almost never look;
behind the baseboards, under the window sill.

What do spiders eat?

A representative of the described species is able to do without food and water for a long time. The spider preys on insects, including their larvae. Hermites, however, do not despise their fellows and small vertebrates. Unlike most other species, recluse spiders do not use webs to catch prey.

Flies and mosquitoes

Spiders hunt their prey while moving away from the nest. The killing is carried out by injecting a toxin from special glands located on the cephalothorax.

The hunter spider does not resort to preserving the prey with a net, but immediately begins to process it, tearing the meat with its jaws and injecting gastric juice.

Insects

When hunting insects, spiders wait for the deadly effect of the poison. After the prey dies, they proceed to eat, turning the carcass into a comfortable position as they eat.

Insect larvae

The easiest prey for hermits due to low mobility and lack of immunity.

How to get rid of it?

The fight against unpleasant neighbors in the house must begin with mechanical capture or destruction of arthropods.

mosquito net

What to do next:

Spiders must be prevented from entering housing. To do this, the windows should be covered with mosquito nets (at the same time flies and mosquitoes will not fly in);
Seal cracks and holes (putty, fill with foam);
Get rid of pests to deprive spiders of food. Mosquito nets will come in handy;
Cover the ventilation grilles with fine mesh (at the same time cockroaches will not get in);
Carry out a thorough cleaning, sort out heaps of rubbish in closets, basements, and on the balcony;
Eliminate leaks and dry all rooms.

To get rid of spiders, you can use folk remedies:

Boric acid is poisonous to all living beings, including arthropods. 1 tbsp. l. The powder should be diluted in 1 liter of clean water, and the solution should be used to wipe the corners and surfaces where spiders were noticed. When using, you should take precautions, do not apply treatment near pets, children, and remove food products.
Essential oils of mint, tea tree, eucalyptus, and citrus fruits (lemon, orange, grapefruit) perfectly repel arthropods. Dilute 15 drops in 1 liter of water. Spray the spiders' habitats with the resulting aromatic liquid.
the chestnut fruits and scatter them on the floor, under furniture, in the bathroom, pantry, behind baseboards.
Diatomite (other names: keselkur, mountain earth) is a sedimentary rock with a high concentration of silicon; it is not dangerous for humans and domestic animals. The abrasive powder is used in the same way as crushed chestnuts (see above).
Table vinegar (9%) is sprayed onto spider nests.

Ready-made chemicals for fighting spiders are available in a wide range.

An aqueous solution of the drug “Butox 50” (30 ml per 10 liters of water) is sprayed onto the masonry site. After 20 minutes, the area is washed with a large amount of soap solution.
Dobrokhim Phos is used similarly, dosage 10 ml per 1 liter. water.
An insecticidal pencil (crayon) is also harmful to spiders.
Sprays such as “Dichlorvos” and “Raid” are sprayed in the habitats of spiders, then the room is ventilated.
Trap tablets attract spiders with their scent. After some time, the animals die.
A relatively new way to combat spiders is aquafumigators. Within 10-12 hours, all flying and crawling insects, spiders, bedbugs, etc. die in the room.

Classification and habitat

There are three types of house recluse spiders:

brown;
black;
brown.

This arthropod is found on three continents, including:

Africa;
North and South America.
The Mediterranean variety of spiders, which are harmless to humans, are found in Europe. Other species are rare and occasionally enter areas or vehicles. The hermit spider in Russia is widespread in the middle and southern latitudes; in the north they live in human houses and utility rooms.

Reasons for appearance

Spiders settle where there is food. If the home is perfectly clean and there are no small insects to hunt, then spiders are unlikely to settle in the home. Some individuals can climb into an apartment from a nearby tree or through a choke, but in the absence of favorable conditions, if there is no food in the room, spiders do not stay for long and crawl into neighboring dwellings.

The risk of colonization by eight-legged arthropods increases in the presence of factors:

the housewife rarely cleans the house;
a lot of dust and debris accumulate in secluded places; there are dark areas where it is easy to create cobwebs;
food for spiders lives in the home: cockroaches (Prussians), red house ants, flies, beetles, midges;
unsanitary conditions, clutter combined with a lack of sunlight and infrequent treatment of hard-to-reach places;
the gaps between the front door and the staircase are poorly sealed, there are access areas through air vents, torn mosquito nets, cracks in the floor and walls, near sewer pipes, through cracked balcony frames and wooden doors;
the owners did not install mosquito nets on the windows or the structure is worn out, there are holes and torn areas; in the dark, when the lights in the apartment are turned on, spiders easily sneak into the home. Until the situation with the protective net is corrected, it is advisable not to light a light bulb in the room or close the windows in the evening: not only spiders, but also mosquitoes, midges, moths, and butterflies penetrate into a lit home.

Correct interpretation of signs with spiders

Options for dealing with spiders depending on location

When exterminating spiders, the main thing is not to go to extremes. Before you sweep all possible remedies from store shelves, assess the scale of the disaster. Much depends on the room and place in which the arachnids have settled.

In a country house

In a country house or in a private house, life without spiders is impossible. But their presence also has its advantages. They will help you get rid of almost all annoying insects (cockroaches, flies, mosquitoes, etc.). To protect the room itself from eight-legged “pets”, take care to install mosquito nets on windows and doors with the smallest holes.

Do not forget about external lighting, light attracts mosquitoes and moths, and spiders come after them to prey on them. Try to turn on the lights as little as possible, or replace regular lamps with yellow-light sodium gas-discharge lamps.

On a personal plot

Spiders in the garden or in greenhouses do more good than harm, so it is not worth exterminating them. They help protect seedlings from pests such as aphids, bugs, leaf rollers. If spiders still haunt you, plant peppermint in your garden.

In the flower garden

In the garden and flower garden the situation is the same as in the vegetable garden; there are no problems with spiders, other than cobwebs and a frightening appearance. You can plant the same mint or install an ultrasonic repeller; along with spiders, other insects will also leave your garden.

In a garage or car

For most people, a garage is the same as an attic; all unnecessary things are stored there. A cluttered room is simply a paradise for a spider, and if there are large cracks in the garage, then insects from all over the area will crawl towards you. They can move from the garage to the car, and there are hardly anyone who will appreciate such passengers. The fight scheme is the same:

thorough cleaning;
blockage of all cracks and holes;
treating the premises with chemicals or improvised means.

Why does a spider crawl in bed, on a bed, on a pillow: a sign

A spider seen in the bedroom and in a place to sleep should also be taken as a sign.

Signs and interpretations:

A spider on the bed means betrayal by one of the spouses or possible deception on the part of a loved one.
A spider on the wall near the bed means that one of the spouses has a rival.
A spider crawled out from under the bed - deception and betrayal of one of the spouses, a loved one.
Spider on the pillow - male infidelity
A spider on the ceiling above the bed - quarrels, problems and scandals caused by the betrayal of spouses.

The spider and the signs it brings

What not to use for fighting

When exterminating spiders, you should avoid using the following methods:

Use of ineffective drugs. When choosing a chemical, it is important to ensure that it is intended to control arthropods. Most drugs against flies and mosquitoes can only stupefy the spider, but not kill it.
Sticky tapes. Many arthropods live in one place, weaving webs and waiting for their prey. Therefore, catching them with Velcro is practically useless.
Collecting spiders by hand. Some gardeners prefer to collect adult individuals in jars and then destroy them or transfer them to another place, but this method is ineffective and dangerous. To clear an area of spiders, you have to risk your own health. According to pediatrician Komarovsky, an arthropod bite can be accompanied by severe pain and the development of an allergic reaction.
Used to scare away dead spiders. There is no point in laying out the corpses of arthropods on the site, since this does not affect the behavior of their relatives.

If there are few spiders in the dacha and they do not cause discomfort, there is no need to exterminate them. In nature, arthropods perform an important function by reducing insect populations and protecting plants from pests. This recommendation does not apply to areas with large numbers of spiders. The magazine “Super Summer Resident” recommends: “when a large space is covered with cobwebs, you should contact the sanitary service.”
