Extermination of spiders
There are several thousand species of spiders in the world. In Quebec, known spiders comprise more than 600 species. The largest family present is that of the Linyphiidae.
The fertilization process is characterized by egg laying in capsules. Each of these capsules can contain up to 1000 eggs depending on the species. Each spider must go through several metamorphoses before reaching full maturity.
There are no threatening and poisonous spiders in Quebec, only Cheiracanthium mildei sometimes inflicts bites that can cause skin reactions.
It can also happen that some species such as the Black Widoow, Latrodectus mactans(black widow)very dangerous are transported by train or boat, in goods from tropical countries. It is important to check the provenance of foreign goods. We have dealt with warehouses invaded by these visitors from California and Mexico.
The Black Widow (Black Widoow) Latrodectus mactans is a small spider whose venomous bite can be fatal to humans. It feeds on insects.
Spiders don’t sting, they bite
Its bite contains a toxic poison that paralyzes breathing and can lead to death. The black widow is about 15 mm, but the male is smaller and measures only 7 mm.
She has 8 eyes and 2 hooks with which she injects her venom.
Only the female is dangerous and is recognized by the red dots she wears on her back, or also a shape of two reddish triangles on the abdomen. The American Black Widow is the most dangerous. Its lifespan is about a year and a half while the male lives only 8 months.
Mating lasts only a few seconds and the male flees immediately, as he may well be eaten.
The Black Widow
We usually find the black widow on fresh fruits and vegetables.
During the summer, in the warm regions of the United States and Canada, it is also found under shrubs and garden plantings. Their legs are long and tapered. The black widow bites to defend herself, if you touch her. His venom is toxic. In the event of a bite, proper and prompt care is required.
Children and adults with unstable health conditions should be extremely careful. They should never interfere with these spiders, in order to avoid being bitten.
