Should i change the bark in my snake's tank?

[frankykeno]

ive had my BP for about 5 months now.. but i never changed the bark inside the tank.. i just shake it around once in awhile 2 get some cleaner pieces on the top.. should i go buy some new bark?

Well let's see, would you enjoy sleeping in your bed if you hadn't changed the sheets in 5 months and you had a problem with bedwetting?
