This evening, once its dark, take your flash light and hold it up to your forehead and sweep the beam across your yard. All those little green and blue shiny dots... Thems spiders!
You can walk in my back yard at night, and watch the wolf spiders scatter!!
I was spraying the weeds in my yard a few weeks ago with a pump up sprayer and the wolf spiders were a scattering! It was like a horror movie, I think there was one or two in every square foot of my entire lot. I'm not exaggerating either.
