Does anyone know how to clean the trees from a cage where the cham has round worms? I use Novasann to wipe daily and clean cages but don't know how to clean a tree in winter in Montana. I can toss the plant but plants are extremely hard to get up here in the winter. I can't have them shipped by LLL or whoever as they would freeze before arrival. Also how long can a round worm live outside the host? Thanks.
