I use to gut load crickets for my reptiles, but I didn't get the sense that the OP was gut loading them. But why go through the effort of gut loading when you can just give high quality pellets imho
I go through the effort because it has worked for me for 2decades of raising aros along with superworms and the dreaded thawed MP. When I kept crickets alive and dealt with that mess..that was effort. But 1k count boxes of crickets and gutloading them with minced baby spinach n baby carrot while they're still in the box (unopened) isn't much effort at all. Throw the box in the freezer for 30min, bag them up..easy peezy..not too far from the ease of pellets and plenty healthy too
