Bleach kills all teh bugs and parasites living on /in the wood.
depending on the size put them in a tub or trash can with water and bleach.. let them set for a night.. rinse them off and all will be well
I bake my branches at 350 for an hour for my panther chameleon. Bleach works even better but if your impatient like me baking them in the oven is just as good :main_yes:
