SAD, I myself am SOO against the use of chemicals when it comes to treatment of mites on snakes..I would have suggested soaking it in water to kill/drown any harboring mites and hydrate..Then being a rosy I would have set it up in a VERY dry habitat without water for 2 weeks..( rosies have been maintained without water for extended periods) Mites also desicate (dry up) and gone from there..2 food items may have been too much for the creature, hopefully it wasn't poisioned by the use of chemicals..Additional info would be of help..
