Hi, my question is When is ring worm no longer contagious in guinea pigs? Is there certain signs? Or a time period or both.

I’ve no clue. But have a read of the guide below. Remember the spores can remain on washable bedding, cardboard and wood. It’s advised you soak the wood and wash bedding on a high temp. Anything cardboard should be thrown away.

Spores can live in the environment, in cracks in the cages etc, for well over a year so hygiene is vital - deep cleaning everything with a good disinfectant such as F10 (which is vet grade and does kill ringworm spores, other cage Cleaners may not), then the spores can remain and cause reinfection
