Pinworms can be contracted through sand. You may have heard of kids getting pinworms from playing in sand. Crickets are also a known vector for pinworms.
For those of you who use play sand for substrate, you may want to reconsider. I am currently treating my dragons for pinworms (panacur), but don't know how exactly they contracted them. I am eliminating all possibilities though...
I know the Reptile Sand or CalciSand sold in pet stores can be a little expensive (~$5-$6 for a small bag), but it is worth getting for you beardies sake.
Play sand can be bought at stores like Home Depot or Lowe's for ~$1-$2, but cheaper is not always better.
