Cockroaches might not be able to survive a nuclear war, but they sure can survive an attack from your broomstick!  Cockroaches can run up to 50 times their body length in one second, and they can squeeze through cracks as small as 3 millimeters. They also can withstand forces up to 900 times their body weight.  These invincible creatures also can quickly develop a resistance to insecticides, which is why it's always important to implement multiple control techniques.
