Silkworms are great, but I always felt they’re very hit or miss. Sometimes you order them and they die so easily, other times they live long

. Naturally they tend to be susceptible to a lot of pathogens and require a bit of upkeep.
You can order banded crickets, pet store crickets are almost always crap and just waiting to spread parasites. Banded crickets don’t die easily if kept correctly.
On paper BSFL are fairly nutritious, but I question their digestibility. They’ll often pop up in the poop undigested. Not to say you shouldn’t feed them and I think it’s great that they can hatch into flies as well. They’re just wayyyy overhyped. IDK how many people I’ve seen talk about them like they’re a super food that can replace everything without even needing dusting… having a good calcium to phosphorus ratio doesn’t mean they have every vitamin and mineral an animal needs lol.
There’s a lot of great feeders, search some of my more recent thread posts. I threw a lot of options out there in a couple of threads not too long ago.
