Would this damage my car?
I just learned about this "Underground Exterminator" product (please follow link below). Sounds like it could fix my garden pest problem. However, a friend tells me that if the engine is forced to run for 15-30 minutes exhausting into a garden hose, it might get damaged before the 30 minutes were up.
What do you think?
Many thanks in advance.
