Gigantic spiders , more like disgusting cockroaches !! I'm lucky enough to live very close to a reptile store. they have all size crickets . usually regular pet stores only have 2 size crickets , small and large. it gets to the point that small are too small, but the large are too large. your beardie could probably eat 3/4 size crix, my beardies are 15 and 16 inches and they've been eating 3/4 crix for awhile now, probably since they've been 13 inches, and i have no problems. if you give your beardie larger crickets you probably won't go thru them as fast either, since the bigger ones are meatier and your beardie won't require as many.
