Ah yes, the false widow spider, thats another creature that is 'over hysterified' (made up word). I know some people do react badly to them, someone in my family did and had a lot of swelling and pain/infection. I used to feel the same way until I saw someone saving a nest of them by transfering on his bare hands (unbitten, and yes he knew they were false widow). I was horrified, and then looked up info about them, as below, taken from natural history museum site...

False widows are not the deadly spiders they are sometimes thought to be.

Although false widows do have a venomous bite, the venom is not particularly potent. Usually the only symptom is pain at the site which may radiate away from the bite. It ordinarily lasts between one and 12 hours, and rarely for more than 24 hours.
Often, the symptoms are no worse than the pain of a wasp sting.
Males are more prone to biting. But this is only because they leave the nest in search of a mate, often venturing indoors looking for females. They are only known to bite when provoked or trapped against skin.

There are sometimes reports of false widow bites that present with more sinister symptoms like rotting flesh and excruciating pain. But these are usually not backed up with formal spider identification.

The extreme side effects experienced are most likely the result of a secondary infection, likely bacterial, if the wound is not kept clean.
There is often hysteria surrounding these spiders, and they have unjustly earned a reputation for being a dangerous pest. But these spiders only bite when they feel threatened.
Jan Beccaloni, Curator of Arachnida and Myriapoda, says 'During my time at the Natural History Museum I have, not surprisingly, met many people who are scared of spiders. That’s a great pity because spiders are awesome creatures which are sadly misunderstood.

'Aside from their key role in feeding on pest insect species, their silk is being developed to make specialist clothing such as bullet-proof vests and their venom can be used in pain relief.
'So next time you find an unwanted spider in your house, please don’t kill it! Either leave it in peace, or humanely put it out in your shed.'
False widows can live in relative harmony with us - they're even tidy houseguests, helping to keep the place clear of flying insects and other pesky invertebrates.
