BEARDED DRAGON SMALL INSECT INFESTATION

Question
WE RECENTLY PURCHASED A LARGE BREEDERS TANK AND NOTICED SOON AFTER THAT THERE WERE SMALL INSECTS ROUGHLY THE SIZE OF ANTS CRAWLING AROUND IN THE SAND. WE IMMEDIATELY THOUGHT THAT THEY WERE SOME KIND OF HARMFUL PARASITE AND COMPLETELY REPLACED EVERYTHING INSIDE. I HAVE SINCE CONSIDERED THE POSSIBILITY THAT THEY WERE YOUNG CRICKETS. THEY WERE SO SMALL WE COULDN'T TELL. ONE THING THAT CHANGED WITH THE LARGER HABITAT IS THAT THE ADULT CRICKETS HAD MORE PLACES TO HIDE AND SOMETIMES WOULD BE ALIVE INSIDE FOR DAYS (I COULD HEAR THEM DAYS LATER). IS IT POSSIBLE THAT THE TINY GNAT LOOKING INSECTS WERE BABY CRICKETS? AND IF SO, IS THERE A NEED TO BE ALARMED IF IT HAPPENS AGAIN?

Answer
Hello Shirl,
Yes, if they looked like tiny ants, they were baby crickets.  Too bad.  
They are so so tiny that unless you have seen them before you could mistake them for something else.  
The adult crickets need places to lay eggs such as soil or moss usually works best but it has to stay moist.  I am surprised some hatched if you did not have any humidity for them!  :-))
Well, no need to be alarmed just do not leave any crickets to hatch in with a bearded dragon so they don't bite him.
