Who's the spider ?

L'araignée : Latrodectus tredecimguttatusThe spider is part of the large family of arthropods (articulated feet) such as insects, and belongs to the class of arachnides such as aan, tick or scorpion.

Small difference with the family of insects, it has 8 legs instead of 6 and its body is composed of 2 parts, the head and the abdomen, instead of 3 for insects (the 1000 legs being of course part of the exceptions)..

His name would come from Greek mythology: arached, great tisseuse and embroidered, provoked the anger of athena that transformed it into spider.

  

Fear of spider or arachnophobia

L'araignée : Steatoda bipunctata Most people are afraid of spiders and this for a very long time, but few people really know why ! 

It is likely that this fear comes from rumours like what spider steals, that it is dangerous, that it can be mortal, attack man, lay under the skin, ... most of these rumours are false or out of their contexts.
The spider, unlike the scorpions, cannot sting but it can possibly bite. in france, very few species are physically able to bite a human being (the gap of the hooks being too low). Only 12 of them can penetrate our skin.
When talking about spider bites, it is usually a slight irritation caused by the injection of venom between the dermis and the epidermis. Apart from an allergic reaction like with the wasps, bees or fries, the "piqûre" is quite benign.
In most cases, when you titilate a spider, either she flees, or she folds her legs and dies.
Spider is not a vampire, unlike mosquitoes, ticks or bed bugs. If she bites, it's just to defend herself and not to feed herself. but it is true, with a few exceptions, that the spiders have avenine glands, which serves them to paralyse their prey.
Aachnophobia can be treated. There are several therapies that will help you lose this spider phobia.

 

Is the spider dangerous ?

L'araignée : Segestria florentina There are about 40,000 species of spiders in the world, of which 1,600 species in france but only about ten are dangerous to man.
Most European spiders live only a year. Depending on the species, they perform from 5 to 10 mues to the adult stage where they are able to reproduce.
For most spider bites, a simple disinfectant is required. but for some particularly venomous species, it will not be sufficient. following the venom there may be neurovegetative disorders, headaches, muscle spasms, paresthesia, psychic disorders, nausea, erythema and local edema. In all these cases, you must immediately go to the hospital.

On the entire American continent there is a particularly dangerous species, latrodectus mactans (black). its venom contains alpha-latrotoxin, a powerful neurotoxic.
The most dangerous in the world is the mexicanus latrodectus mactans but be reassured, it is normally not found in france.
The latrodectus tredecimguttatus (the malmignatte,) cousin of the famous black widow, can meet in the south of the france but also along the Atlantic coast to Morbihan. this spider appreciates the immediate vicinity of our homes. Morsure cases are more common.
Can also be found in france:
- the lycose of narbonne (lycosa narbonensis): living away from any dwelling, it is rarely in contact with man
- Florentine segestria (segestria florentina): this species, which can be found everywhere in france, dwells in the holes of the walls. It is therefore often present near the dwellings. This spider is not particularly aggressive "if you don't bother her, she won't bother you!"
- the steatoda nobilis: although a native of the Canary Islands, it is extremely common in the south of the Corsica. It is found everywhere on vegetation, tree bark, kidneys, buildings.

We still have to relativize. in france, only a few large species can be dangerous for man (such as latrodectus whose bite is particularly venomous but who is very well treated in hospital). Spiders are in fact much more harmless than wasps and mosquitoes, and for the moment, no cases of death caused by a spider bite from france have ever been identified.

To learn more about the malmignatte see the site INRA and for the black widow wikipedia

 

Is the spider useful or harmful ?

L'araignée : Lycosa narbonensis

Except for a risk of bite by a person who has enfiled a garment or put a pair of shoes with the spider in, the spider is more useful than harmful.
Apart from the bagheera kiplingi, South American spider, which mainly feeds with acacia shoots, spiders are carnivorous and kill mainly flying or crawling insects. They catch them either using traps or on the lookout. They can also feed on small crustaceans such as cloports or even other spiders.

We will not go so far as to say that we have to do a spider farm in his home to get rid of flies and mosquitoes but if you have some and they don't bother you, leave them alone !
In order to respect the balance of nature, the spider also to its predators. of course there is man and his pesticides... but also birds, lizards, insects like religious mantle, and even other spiders.

 

The hawking spider or opiliones

L'araignée faucheuse - Pholcus phalangioidesMost people who do not support spiders tolerate the hawk (pholcus phalangioides), probably because everyone knows it is perfectly harmless. And it's true! This spider is safe for man. It has neither venom nor silk (no gland to weave canvases).

 

Unlike other spiders, she will also feed herself with already dead prey. This spider that is carnivorous, feeds on insect bodies or other small animals. she captures her prey with hooks around her mouth. the paws of the opiliones are easily removed, so it is not uncommon to meet individuals with less than eight paws.

 

According to some gardeners, opilione would be a predator of the red spider, frequent in plants. Its predators are mainly birds, reptiles, spiders and other carnivorous insects.

 

How do I get the spider away ?

The spiders being frilous, they go back mainly to the houses in the autumn, hoping to find a little dark and hot corner.
To get them away, we found on different forums (we let you test them):

  • in the various pieces, place in a cupella some tomato leaves,
  • the chestnut wood and chestnuts: the smell is unbearable and makes them flee. It is true that on the chestnut carpenters, you never see a spider's canvas !
  • put gasoline of turkey or turkeyessential oil of lavender on the edge of the doors and windows,
  • apply a mixture of 0.5 litre of oil on your oils white vinegar added 40 drops ofessential oil of niaouli,
  • pass a potassium alun solution (80g of alun stone in a liter of warm water) on the door and window contours.

 

Our repulsive "Repulsive insect habitat"will also give very good results. composed of citriodiol, extracted from eucalyptus citriodora, this substance has a very powerful repulsive power.
