I had my dragons out in the trees when I was taking photos back about six months ago.
I didnt notice it right away but shortly after I noticed a red small mite on one of my dragons.
I started to investigate and realized they were all infested with these little red mites.
They were soft bodied and if sprayed with mite off would almost instantly let go and then were easy to get off. Otherwise without the mite off... they would stay pretty well attached and if scrubbed hard enough they would burst. They were about the size of the tip of a number two pencil led if sharpened to a fine point.
They would go mostly into the armpits and tail region and neck also. I had to scrub everything and bleach all the furniture for weeks to finally rid my dragons of them.
If your working with an enclosure of some sort I dont think its as big of a deal but when you let them scamper around under or in trees it could be an issue and if I ever do that again I will pretreat with mite off first.
They may be regionally specific to Florida.
I only had small amounts like 5 or six on each dragon.
here is a dragon infested with red mites:
