How to identify a Brazilian Wandering Spider
The Brazilian Wandering Spider can be identified by its physical characteristics. It has a large, robust body with long legs and a distinctive pattern on its abdomen. The spider’s body is usually brown or tan in color, with darker markings that resemble a violin shape on its abdomen.
One way to differentiate between male and female Brazilian Wandering Spiders is by looking at their pedipalps, which are appendages near their mouth used for mating. Male spiders have enlarged pedipalps that resemble boxing gloves, while female spiders have smaller, less pronounced pedipalps.
The venom of the Brazilian Wandering Spider
The venom of the Brazilian Wandering Spider is extremely potent and can cause severe symptoms in humans. It contains a neurotoxin called PhTx3, which affects the nervous system and can lead to paralysis. The venom also contains other toxins that can cause pain, inflammation, and tissue damage.
The potency of the venom varies depending on the species of Brazilian Wandering Spider. Some species have venom that is more potent than others, but all are considered dangerous to humans. The venom is primarily used to immobilize and kill the spider’s prey, which includes insects, small mammals, and even other spiders.

Prevention of Brazilian Wandering Spider bites
To avoid encounters with Brazilian Wandering Spiders, it is important to take certain precautions. When traveling to regions where the spider is commonly found, it is advisable to wear protective clothing such as long sleeves and pants. It is also important to shake out clothing and shoes before putting them on, as spiders may hide in them.

Seal any cracks or openings in walls, windows, and doors to prevent spiders from entering. Regularly inspect and clean outdoor areas such as gardens and sheds to remove potential hiding spots for spiders.
