Brown recluse female, 10 – 11 mm, very poisonous.
Whether crawling on eight legs along their webs or scurrying from their dens – ready to pounce and kill anything that they wish to eat – spiders can be the stuff of nightmares. Yet, even as they spin their silk to lure hapless prey, spiders hold a fascination for us as well.
Many spiders are venomous, of course, and some can even kill people; they can certainly kill their dinner many times over! Here we take a look at the ten most venomous spiders on earth – taking into account not just the toxicity of the venom but also the amount the spider administers (and its aggressiveness as well).

10. Yellow Sac Spider
The beautiful Yellow sac spider is one of the least venomous in our list – but is still a seriously poisonous proposition. Yellow sac spiders are likely to make the drag line webs of the type you might get rid of with a broom or vacuum cleaner, but thankfully they rarely get near humans to bite. One of the dangers of their bite is a close connection with MRSA infections, which can be very serious; however the level of toxicity itself is disputed, even though the bite can leave necrotic – or dead tissue – lesions.
