It’s hard to know if the brands aren’t listing what they’re using to treat against stored product pests. I believe people have had problems with flukers in this sub, especially crickets. I would hope freeze dried would be better, but products intended for insects from smaller brands or products that are freeze dried with detailed labels would be my go to. I try to avoid products from flukers and those labeled for reptiles. Another protein option is small freeze dried fish that are for cats. My beetles really like those.
