In summary - keep on or start worm farming, but be aware that there are
pros and cons to using castings. With a bit of knowledge and observation you

A caution: As said above, raw organic matter is full of pathogens.
Vermicompost is not pure worm castings, i.e. it does have a component of
unbroken down organic matter. Be careful handling this material since
disturbing it will generate clouds of airborne fungal spores and toxic
bacteria, which can give you what?s called organic dust toxic syndrome (ODTS).
ODTS features symptoms such as gastrointestinal upsets, influenza type
symptoms and irritation to the airways.[4] You?ll be more likely to have
problems in summertime, when everything is dustier, so wearing a dust mask is
recommended.[5]
