Anyone have (or have had) a black widow (or any other species of widow) problem?

I have a horrible brown widow infestation (yes…I said brown!), mainly in my back yard. The eggs are all over the place, under lawn furniture, my childrens toys, etc. I have had an exterminator come twice in the last year and they keep coming back. I’m scared to let my kids go outside and play!!! I’ve even gathered up some of the eggs myself and torched them but one of them broke and little widows crawled out all over so that was not the best of ideas, but I dont know how else to get rid of them!! Help!!! :-O
