In San Diego California Brown Widows are taking over Black widows areas.
On any given night, I can go in my backyard and find a dozen of them.
I tried spraying them however, they play dead and then when you come back they are gone.
They get on lawn furniture and hide out in the day and at night they come out. They females have egg sacks that can contain up to 200 spiders.
