Answer:
People are hired to get rid of me. I'm often hiding under your bed. In time I'll always return you see. Bite me and you're surely dead.
As soft as silk, as white as milk, as bitter as gall, a thick green wall, and a green coat covers me all.
Through its wounds, water does run. It once held many but now has none. What is it?
Add a T and I shoot through the sky. Then add an S and I multiply. What word is it?
I always run but never walk, I sometimes sing but cannot talk, No head on which a hat to place, You always look me in the face.
The warmer I am the fresher I am.
