Spiders, despite their bad press (and the significant percentage of people who feel phobia towards them), are often our allies. Despite the fact that thousands of bites of them are reported every year around the world, it is actually quite rare for a spider to bite a human being .
In fact, most bites are actually infections due to MRSA resistant bacteria misdiagnosed by patients and doctors, as Rob Dunn points out in his book Home Alone?
How much do you need to bother the spider to bite?
Spiders use their venom mostly for their prey, not for defense. So it is almost always easier for spiders to flee than to fight. There is even a study that tried to calculate how many times you need to harass a spider to get bitten. It was made with 43 specimens of black widow spider and had to bite an artificial finger.
After 70 pushes with the artificial fingers, no spider stung:
The only time the study found that a black widow stung the artificial fingers was when they were used intentionally three times in a row to crush the spider. Sixty percent of spiders imprisoned three times in a row between two artificial fingers bite. And even then the spiders released venom only half the time, so half the bites weren’t troublesome, just painful. Venom is expensive for spiders, and they are not willing to waste it on us; They reserve it for mosquitoes and house flies.
That does not mean that there are no bites, but that they are very unlikely. The banana spider, Brazilian wandering spider or armadeira, for example, is the most poisonous spider in the world (0.006 milligrams of its venom is enough to kill a mouse), and it produces more than 2,700 bites annually in Brazil (although only two or three deaths ). When it happens, yes, it causes a long and painful erection in men.
