I agree with the need for change in the temp readings and need for thermostat. I am a bit confused as far as not wanting to aggressively treat for mites. PAM or Provent-a-mite (not the cooking spray) can be treatment for mites but like the title says it also prevents mites. Its a quick, easy way to stop mites if you got them or prevent them if you dont. Either way I wouldnt consider it aggressive, although if it is mites and you dont treat them... they may get out of hand a require aggressive treatment.
