this is how ive dealt with mites.

get tthe hottest freshest chillis u can. dice them and cover with boiled water.
i use 1 cup chillis and cover with 1 cup boiling water.
let it soak overnight. strain and top up this concentrate with water in a 500ml sprayer. spray all over, undersides, every bit of em. wear dustmask and goggle/sunnies. this shit burns to breathe.
make sure lights are off or its done in the cool of the day.
repeat next day.

worked wonders for me.
all the best.
