There Are Some Treatment Resistant Strains Of Skin Mites Cropping

There are some treatment resistant strains of skin mites cropping up (see cdc petition and or bird mites.org) which medical science is laggging on acknowledging meanwhile people are seriously suffering and are NOT delusional parasitosis and need something other than the standard permithrin or ivermectin. If they reach out they are slapped down or given the runaround by un up to date docs. Question can you help me locate Spregal spray in the USA? Thx
