LOL funny you say no proof but
myself 10 years no deaths or illnesses from using it ..
people who been in reptiles longer then me using it same thing no deaths or illnesses ...
the ton of people i have recommended it to thank me for doing so
and they have not had 1 death or illness from using it .

PAM / death to snake if inhaled, but yet effective on mites
Powder / no deaths to date from using it and yet is effective on killing mites .


guess the proofs in the usage for over 10 years .

so use what u like , we all have our opinons on what works best
the OP needed help and i helped him .
if you dont like it keep using what your using , its that simple ..
