Yesterday I discovered what I believe to be false widow spiders on my decking, a couple of years ago a saw one in my shed but didn't think to much about it, however I have a seven year old and two younger grandsons who are always playing on or around the decking, should I be worried?.
I am pretty sure this is what they are as when I was younger I lived in Australia and these look just like the red back only with beige makings on there back rather than the red.
Any help would be much appreciated.
