I wouldn't just use that as a diet. If you can't stand live crickets then you probably should reconsider keeping an insectivorous animal like tree frogs. Just a thought
Canned insects often lack a lot of nutritional value. Also they may have "enhancements" that really aren't good for critters. Also frogs don't normally take to dead bugs. My bullfrog and pacific tree frogs only ate live and only when it was moving lots. I will second the idea for dubias I clean my dubia tub 2x a week and that only consists of pulling out the paper towel with the food on it and replacing it. My dubias produce around 30 babies a month and I only have 8 females a lot of this also depends on what type of tree frogs you are wanting. Red eyes and monkey frogs probably won't take bigger dubias, where dumpys or Cubans and other thicker tree frogs would probably love some bulkier dubias.
I only had one frog that ever took dead food, and I raised him from a tadpole. don't know what kind it was. but even he would only eat something that he "perceived" to have moved.
