We had those spiders in droves at our farm. They like to web between things...like posts, fence rails, etc....not so much in corners. They start off quite small (and manageably sized) then over the summer they grow to enormous proportions...I have seen a few the size of my hand.

When we first moved in, the whole farm was very overgrown and unused...the people who owned it previously were old and died and the place sat empty. When we moved, we used the side door to go in and out...close to the garage and just easier. So on the second day I brought my horses, but no cross fencing yet, so they just grazed at large. In the middle of the night, I heard a creaking and looked out the window to see my big Irish horse scratching his butt on the front pillars. He is a big guy and I was afraid he was going to knock the porch down! So I went charging down the stairs and out the FRONT door to whack Curragh on the backside to stop his scratching. I opened the unused front door and went face - first into one of those spiders in all its full sized glory. Much screaming and arm waving followed...I am sure the spider was just as surprised to be awakened by a charging woman only to be flung about my frenzied waving.

I scared Curragh half to death...and stopped his butt scratching in the process.

Also, the babies are carried on Mom's back...I know this because I accidentally got one in the line of fire of the fly spray. About a zillion little dots popped off Mom and ran for their lives. It was amazing...because you can't see them otherwise.
