If there is a certainty they would not be contaminated with pesticides, yes,
It is easy enough to breed your own feeders, maybe consider that. Crickets, meal and wax worms, fly larvae etc.
I had a good number of spiders I tried breeding earwigs for, it works, but they don't populate very fast.
Breed meal worms, you can have more than you need, feed excess to the wild fence lizards and birds. The adult darkling beetle may be too hard for their liking, but some needed for propagating colonies.
