Who. Phoneutria. Where. Brazil Brazil. The world's most venomous spiders are the Brazilian wandering spiders of the genus Phoneutria, and particularly the Brazilian huntsman Phoneutria fera, which has the most active neurotoxic venom of any living spider. Its venom is so potent that only 0.006 mg (0.00000021 oz) is sufficient to kill a mouse. Phoneutria spiders are usually dark in colour and have a body-and-leg spread of approximately 17 cm (6.75 in). These large and highly aggressive creatures often enter human dwellings and hide in clothing or shoes.
That's how they hunt. Most spiders are too small, or their venom too weak, to be dangerous to humans. Some spiders are pretty well-known and seem to get blamed for most of the spider bites out there. In the United States, black widow spiders are often considered the most venomous.
