I'm sort of in the country and backed up to woods and I've noticed a lack of spiders, too. Used to see jumpers, daddy longlegs, crab spiders, all kinds. Also had orb-weavers, all over the outside back of the house. Beautiful webs in the corners of windows, the sliders, between the gutters and downspouts, everywhere. Fascinating, watching them spin their webs each night. Past couple years? Not a one in sight. I kind of miss them!
