Lately I've been using grubco for my feeders because they dont charge me for shipping But, after using their larvae i noticed that one of my BDs "droppings" was rather...liquidy and smelt horrible. That sounds like parasites right? Guess i'll be tossing the rest of my larvae...and noww ill have to take my 2nd BD to the vet also because shes been eating from the same feeders! Just a heads up...
