I'm going to try some.
I've had such a problem feeding commercial crickets and edema in the quads. There is no doubt in my mind that some crickets will immediately cause edemas. I don't know if it is the supplier's feed or what the pet shop feeds them once they get them, but it doesn't matter how long I hold them (sometimes more than 2 weeks) feeding really nutritious foods like fresh grass and cricket crack. They can still instantly cause most of my quads to develop an edema a day or so after I switch to certain lots of crickets.
Whatever is going into the crickets that seem to bother the quads doesn't clear the crickets' system even after weeks of good food. I'm afraid that the Timberline Vitabugs will have lots of synthetic vitamins that bother the quads.
My veileds have no problems with anything I feed them.
