They inject their venom, which produces toxins called agatoxins. These toxins paralyse the prey, making it very easy for the spider to feed on them.

They simply bite to defend themselves, even though we humans will do the same when threatened.

However, for hypersensitive human skin, it is advised that you visit or contact a medical expert near you.
