I found a black widow in my closet today. It was a juvenile male and he'd built a web from the wall to my coat. I killed him. This is the fourth black widow I've seen around my house recently but it's the first one I found inside. About a month ago I found a huge female on my porch with two egg sacs. I didn't have any bug spray so I ran inside and grabbed lysol and sprayed it all over the egg sacs. They shriveled up and turned brown so I'm pretty sure I killed them. The others were one adult male and another adult female on the back porch. My question is what would you do? I guess I should get an exterminator out here. Is there some other approach to keep them out of the yard?
