You must know these dangerous spiders

Such incidents are not uncommon. It was only in May that a supermarket manager discovered a strange spider among bananas in Schöneberg, Bavaria. At first it was suspected that it was a highly venomous Brazilian wandering spider, but this suspicion was not confirmed – fortunately. Because the supermarket manager caught the spider himself with a bottle.

How dangerous are “banana spiders”

First of all: “banana spiders” do not exist like that. However, some types of spider webs are so named because they are frequently found among bananas imported from Brazil or Colombia. But why among bananas of all places?

Spiders are ambush hunters and always prefer to hide where they can hope for prey. Since bananas are always packed in groups, spiders can hide quite well among them. But it is quite clear: spiders are rarely found that are really dangerous to humans.

Because often the animals found are large stray spiders (Cupiennius salei) or the giant warm crab spider, both of which have little interest in biting people. With a size of up to 34 cm, the latter is frightening, but non-toxic to humans.

The situation is different with web spiders (Phoneutria epilata). They are much more aggressive than the spiders we just mentioned, love to bite, but are relatively harmless. Maximum consequences after a bite: swelling and irritation of the lymphatic system. By the way: “Phoneutria” is a Greek word and means “murderer”.

It only gets really dangerous with Brazilian wandering spider (Phoneutria nigriventer) …

Danger among bananas: this is the Brazilian wandering spider

It also belongs to the genus of web spiders and is actually native to South America. But it was repeatedly brought to Europe by freight traffic.

It is particularly aggressive, poisonous in a life-threatening manner, and one of the most dangerous spiders in the world. The Brazilian wandering spider is believed to be responsible for the majority of fatal spider poisoning incidents worldwide. Their venom causes severe pain and can also lead to impotence – if not death – in men.

The big problem in German supermarkets: large wandering spiders are hardly distinguishable from the deadly Brazilian spider with the naked eye.

If you’re really scared, let me tell you: The Brazilian wandering spider isn’t the only deadly specimen. We present the three most venomous spiders in the world.

These are the 3 most dangerous spiders

1. Sydney funnel spider / Brazilian wandering spider

Researchers disagree about which type of spider is the most dangerous in the world. Two species consistently top the rankings: the previously described Brazilian wandering spider and the Australian spider on the Sydney funnel web. Both are in the Guinness Book of Records. Because one bite can kill.

The funnel web spider is very dangerous primarily because it lives within a 100-mile radius of Sydney, where it loves to move into people’s gardens. Their poison is deadly mainly to children and the elderly. In 1981 an antidote was developed.

You will quickly notice if you have been bitten: first, numbness in your mouth, twitches of your tongue, profuse sweating, muscle cramps, high blood pressure, increased heart rate and shortness of breath. Such a spider bites about 30-40 people per year.

2. Black Widow

Even young children know her name: the black widow. Females are dangerous here, males are rarely encountered, as the female eats them after mating – hence the name “black widow”. In the United States alone, about 2,500 people need a bite treatment each year.

A distinction is made between the European or Mediterranean black widow (Latrodectus tredecimguttatus) and the Western black widow – also called the “true widow”.

A bite from the first rarely turns out to be fatal – only in exceptional cases, such as respiratory paralysis or a heart attack. According to experts, the mortality rate is one percent. As the name “Mediterranean black widow” suggests, this species can be found in the Mediterranean region, such as in Italy or in southern France and Spain.

More dangerous “true widows” prefer to migrate to dark and cool places such as basements, huts or toilets … This is also where most bites occur, which victims usually do not notice. The venom acts more slowly than in a funnel-shaped spider or a Brazilian wandering spider: sufferers experience severe pain accompanied by sweating. After a few days, a rash and itching usually appear. In severe cases, it can cause insomnia, high blood pressure, and convulsions. Those who have been bitten usually recover after a few days, but deaths are common.

3. Chilean spider angle

The Chilean corner spider (Loxosceles laeta) may look harmless and small, but it can be deadly. It is native to western South America, especially Chile, hence its name. She especially loves to crawl into dark corners. According to statistics, it is found in up to 40 percent of all Chilean families.

You hardly notice their bites. But within a maximum of two to 18 hours, severe pain usually occurs around the site of the sting. The poison causes severe tissue damage and, in the worst cases, can lead to liver failure. BUT: The Chilean angular spider is not considered aggressive and is also nocturnal, so it rarely bites.
