. They are so hard to kill because of their structure. They have a unique cellular structure. They have a hard outer coat surrounding the spore. This makes it hard for disinfectants to penetrate. There is a very thick layer beneath the coat call the cortex. This gives it resistance to heat. There is a germ cell wall under the cortex.Under the germ cell is the inner membrane and it is a permeability barrier against many potentially damaging chemicals.
