If you cannot identify a spider, why assume it is a false widow?
Please, please, listen the folk who actually work on spiders (in this case = me) - there is basically zero risk from these spiders.
You shouldn't be killing any animal, especially if you can't identify them for certain. There's lots of spiders that look like "false widows" and for starters the ENTIRE GENUS steatoda are not all "false widows" despite what the papers will have you believe.
If papers ran the same headlines for things of equal danger to these spiders then we'd be awash with stories of killer peanuts and genocidal cat and horse hair.
If you read back, I never once said 'assume its a false widow'. I did however say. do not go and wipe out any spider you see..we need them. I also never read the papers, 99% of every story is total bull, and the 1% is suspect. If I want information I go to the source material. In this case keys for the species.
The one I got in the box today was definitely a false widow, and not going by google pics either, since most of those are not, but are showing up in the search.
I did say. Be aware of them, simple.
check boxes for spiders before you open them, and if there is a spider in there, then go careful.
I would much rather be aware of something, than blissfully ignorant of the possibility of them being around. If people are made aware of the facts of false widows, then its also much less likely that they will randomly squish every spider that is near them and be able to identify one if they saw it.
These are also an invading species and not natural to the UK. Would you have people then in essence letting an invasive species loose in their back yard if they found one? hmmm.
As to what was posted earlier about 'pick it up and put it outside'...yeah..advise people to simply pick up a spider that could possibly be venemous and put it outside...great advice.
If you want over-reaction to things, then look at half the posts going on in these forums lately in reply to threads.....
