Why are roaches so unkillable?
They are remarkably strong, which is why they cannot be simply squished. Healing is another attribute that makes these nuisances so invulnerable. Cockroaches can endure horrible injuries due to their ability to regenerate limbs. While they can repair their exterior, they can also heal their body from the inside too.
Why are cockroaches resilient?

Why cockroaches will outlive us all?
According to Slate, it may be "because [roaches] are relatively simple organisms with fewer genes that might develop mutations." Their cells divide far more slowly than human cells, affording the roach's cellular chemistry more time to fix the problems caused by radiation, like broken strands of DNA.
