I ignored them up until I found about 10 large females (and some males) with webs established in about a 30sf rectangular area. Trust me, you cannot co-exist with these spiders.
After considering various means to kill them (salt guns, air gun, shocking devices) I settled on a slingshot loaded with a pinch of clean kitty litter. It's very effective, safe for your property, and safe for your yard. Cheap too. Like a little beehive round for these bastards. I suggest you kill every one you see.
This year I am considering using a pesticide. Can any experts out there suggest what I could use safely? I recall reading that the Joro spider lays eggs in the ground. Please help! Lol.
