I have a Russian (3 years) and a sulcata (about 1 yr) in am outdoor pen about 14ft by 12ft. I was wondering if eucalyptus mulch is safe to use as a substrate both in the outdoor part of the pen and in the deck box where the UVA UVB an heat lamp are...anyone with information on the effects of ingestion and inhalation of eucalyptus mulch/fumes would be appreciated. I live in central Florida if that helps
