First point: almost no garden spider harms humans, except for exceptions like the Brazilian wandering spider, black widow, brown recluse, and others.
The tarantulas (as they are called in Brazil) and tarantulas (in the rest of the world) despite their size and having that look of a nasty creature, are not venomous to humans although their bite is quite painful. The tarantula is an harmless and extremely docile spider with humans. Many people keep these arachnids as pets. Only the urticating hairs it expels when it feels threatened can cause more serious problems if they reach our eyes.
Completely different from tarantulas, one of the most dangerous and aggressive is the Brazilian wandering spider, which is not afraid of anything. Both the brown recluse and the black widow are also dangerous, but these are more fearful; however, if threatened, an attack is certain.
The tarantula (caranguejeira) is a threatened species mainly due to habitat destruction and hunting for keeping as pets. On the other hand, it is one of the most commonly bred spiders in captivity.
There are thousands of spider species (35 thousand in the world), many are harmless, others are not, but all are bothersome when they decide to live inside the house. Some herbs or drops of peppermint, orange, lemon, vinegar, tobacco, lavender, camphor, or cloves around the house are scents that house spiders hate.
Meet the most venomous spiders in the world:
• Brazilian wandering spider: The Brazilian wandering spider is considered the most dangerous in the world, being found in Brazil. To give you an idea, only 0.006 mg of its venom is enough to kill a rat and is more lethal than many snakes.
• Brown recluse: Eight species of brown recluse are found in Brazil. At the site of the bite, necrosis usually occurs. It is not an aggressive spider and can often be found inside shoes.
• Funnel-web spider: The funnel-web spider is native to Australia, and its name comes from the fact that it weaves webs resembling funnels. The venom of the funnel-web spider is one of the most dangerous and can be fatal to humans by affecting the nervous system.
• Black widow: The black widow spider, known for killing and feeding on the male after copulation, is found throughout America. Only females bite humans and cause accidents. Without medical help, the victim can die.
• Mouse spider: The mouse spider is found in Australia, and its name derives from the fact that they dig burrows to serve as hiding places from predators and a safe place to keep their eggs and young. They are not aggressive, but they have a powerful venom.
• Redback spider: The redback spider is native to Australia and introduced in various locations around the world. It is distinguished by the presence of a red longitudinal stripe on the upper part of the abdomen and, like black widows, also feeds on males after copulation. Its bite causes intense pain and has been responsible for the death of some people.
• Sand spider: The sand spider gets its name because it uses sand to camouflage itself, as it inhabits the deserts of Africa and South America. Its bite can lead to death.
Spiders can be terrifying creatures for some people, where 5% of the global population develops what is called arachnophobia.
