What are the small worm things in your hermit crabs cage?

oh yeah i had little white worms in my hermit crabitat a couple of weeks ago...sift the sand or if that will take too long put all the sand on a tray and sit it in the sun for a couple of hrs or put it in the oven. check online to see if they are harmful to our little creepy-crawly friends and check how long it takes for it to bake in an oven! hope this helps! xo
