Any tips? What should I ingest to keep fleas from biting me?

I know of NO. Food or chemical to ingest to prevent flea bites. If you have fleas in your home: wash everything fleas touch w hot water ; dry on high heat. Vacuum house several times.Empty vacuum bag outdoors ; put disposable bag in 2nd sealable bag in outdoor trash can. Spray corners, carpets etc with food grade diatomaceous earth or a natural flea spray. See: http://www.Fleaseason.Com/fleas-humans.Shtml.
