It’s always a good idea to buy organic for the hermit crabs. Hermit crabs are classified as arthropods, like insects and spiders. We really don’t want to be giving them pesticides. However, some fruits and veggies are worse than others. I found a website, EWG that provides a yearly updated guide on the dirty 15 (most pesticides used) and the clean 15 (least pesticides used) and thought I’d share that with you.
