I've got some 100l sacks, in heavy paper, of perlite that I need to store.

Does anyone know if mice will eat the perlite? I know they love
styrofoam, in some ways it's not that different.

Thanks, -E

Perlite is poisonous. Even humans must most definitely not breathe it in let alone eat it...it can cause lung cancer.

Perlite toxicology and epidemiology – a review

"Perlite is a generic name for an amorphous volcanic alumina–silicate
rock that expands by a factor of 4–20 when rapidly heated to 1400–1800?°
F (760–980?°C). Both the ore and the expanded product have extensive and
widespread commercial applications. Limited data on the toxicology of
perlite in animal studies indicate that the LD50 (oral ingestion) is
more than 10?g/kg and, from a chronic inhalation study in guinea pigs
and rats, that the NOAEL for the inhalation pathway is 226?mg/m3. Health
surveillance studies of workers in US perlite mines and expansion plants
(including some workers exposed to levels greater than prevailing
occupational exposure limits (OELs) conducted over 20 years indicate
that the respiratory health of workers is not adversely affected."
