Keeping fleas out of your RV

How do you keep fleas from invading your RV when camping?
Sara in Seattle says, ” I’m a big believer in Borax. Sprinkle it on your carpets in the RV and car. When traveling, just put it around the edges of the carpet. If anyone brings in any fleas, the Borax sucks all the moisture out of their little bodies. Sorry if I sound cruel, but I HATE fleas!”
