Try putting the super worms in a small dish to prevent them from burrowing. I have never used sw's myself so I cannot speak from experience but I do seem to recall reading, possibly more than once, that they can resurface later and eat or chew into your tarantula. I'd probably keep an eye on that until someone can chime in with hard facts on the subject. A forum search may dig up something too.Zorack said:I go to feed my T's the super worms and before they get a sniff, they borrow into the substrate must be about 3 in each now, would this cause a prob (none of them are in molt)
