I recently had the opportunity to see and treat a truly disastrous mite 
infestation. Each line is a record of the mite drops each day after an 
oxalic acid treatment.

August 29:         858, 254, 254,254, 237, 237, 237, 237, 334, 296, 188, 238

Sept 10              2805, 753, 388, 191, 215, 198, 205

Sept 17              2428, 1077, 467, 325, 112, 144, 166

Sept 24              1121, 871, 347, 270, 174,

Sept 29               691, 266, 62, 16, 21

Oct    4                9, 29, 27, 9, 4, 4, 4, 4,

It is hard to draw any conclusions from this, although it appears that 
vaporizing every 5th day is more effective than every 7th day. It  also 
seems that the vapour kills the mites almost immediately and loses its 
effect very quickly.



Best regards,
