Spiders are REALLY tricky to get rid of. I have quarterly pest control and the spiders, they still come. BF goes out at night with flashlight and those big lighters and kills the black widows. (thought this post was his for a minute!) My pest control says that some chemical was banned 5 years ago, and so that is why spiders still come.
Water down as much as you can. Sweep daily. Keep bushes pruned and away from the house. You don’t want to give them anywhere to hide out. The good news is that the widows seem to be seasonal and when the temperature decreases, black widow sightings decrease as well.
