What did you find difficult about raising crickets? I remember as a kid I had a lizard and a cricket box for feeding and it was just a matter of adding cricket food and cardboard tubes (disregarding the one "dropped the box of crickets on the ground and all the crickets escaped into the kitchen" incident, to be fair). That said, I wasn't trying to raise human-food-grade crickets, lizards are probably less picky.
Desperately hoping that this response means you want to catch them from the wild or around your property, and not that your house naturally contains a volume of insects large enough to support a nontrivial population of these things. :)
I tried to grow crickets to make flour out of them, but it was much harder than I thought, those spiders seem easier, and are also meatier.
