Exterminating Rats With Deadly Automobile Exhaust Gas
“IF THE fumes from an automobile exhaust can kill humans, they should have the same effect on rats,” said the head of the Department of Health of Highland Park, Michigan. And so onto the exhaust pipe of a dilapidated Model T Ford discarded by the police officials, the health officers rigged up a rubber hose and established themselves as modern pied pipers.
The “hunters” first seal all the holes of the building to be operated upon, leaving just two openings. The hose is then inserted into one of these, the engine of the Ford coaxed to wheeze a bit, and the carbon monoxide does the rest.
