Oh Gross!

Next suggestion?

Crushed cockroaches can be applied to a stinging wound to help relieve the pain.

And now this ... yuck!!

Cockroaches have quite a capacity for survival. If the head of one is removed carefully, so as to prevent it from bleeding to death, the cockroach can survive for several weeks. When it dies, it is from starvation.

Sorry.  At least I didn't post any pictures.
