I do wonder about women who willingly undergo the pain and trauma of childbirth, but go into a panic at the sight of any harmless spider.
For those who have a genuine spider phobia, it is a horrible affliction. Fortunately in most cases it can be successfully treated, as has been documented on MN at various times.
It doesn't help anyone suffering from spider phobia to make jokes about having to burn the house down. Neither does it help to put up warning flags. As with any phobia, warning and avoidance of something lurking only reinforces the fear.
As for the much hyped 'false widow', steatoda nobilis, it is still quite uncommon in the UK in spite of scare stories in the press. There are many far more numerous spiders that look very similar.
If you actually do see one and can positively identify it you are quite fortunate. If you disturb it sufficiently to provoke a bite you may possibly find it as painful as a wasp sting. If you are one of the minority who suffer a severe allergic reaction to a wasp sting then you may have a similar reaction to a defensive bite from a nobilis. The chances of you having such an allergy and being bitten by one are very remote.
And please, if you do have any anxiety about spiders, do not show it in front of your children or you will be teaching them a fear of these generally harmless and very beneficial creatures.
Sermon over!
