My wife took a photo of this and after a bit of searching, could it be a Spider Wasp?
I have 2 kids under the age of 2 who love to play outside, are they a pest and should i try to exterminate them?

Spider Wasp stalks Spider

Dear Michael,
You are correct that this is a Spider Wasp, and it is stalking a Spider in one of your photos.  You do not need to fear this Spider Wasp attacking your children unless they look like spiders, which we highly doubt.  Female Spider Wasps are more concerned about providing food for their broods than they are about stinging innocent children, though we would not entirely discount the possibility of getting stung if the Spider Wasps are handled or stepped on.  Again, we want to stress that they are not aggressive toward humans and we don’t believe there is any need to take the steps to exterminate them, which would probably be nearly impossible anyways.  Social Wasps pose a much greater threat because they try to defend their nests, while solitary wasps like Spider Wasps do not have the same defense instincts.  We will try to identify both the wasp and the spider after we do some yardwork in our own neglected garden.  Alas, you photo does lack critical detail, but the spider appears to be a Wolf Spider.  We have nice photos in our archive of a Spider Wasp preying upon a Wolf Spider.

One Response to Spider Wasp from Australia stalking a Wolf Spider

    i beg to differ re they wont attack humans
    indeed that are thinking about how to get the paralysed spider back to its nest so they can lay eggs in it but they will attack you if you come too close and they are relentless.
    another time i was trying to save a huntsman spider from a stalking wasp that was chasingg it round and round a flower pot but it attacked me and i fended it off with a tennis racquet. they dont die very easily either.
