Fleas Itching:

Repel fleas with one or two drops of essential oil
of lavender, cloves, citrus or eucalyptus.
Put on yourself, pet, furniture, or rugs either neat,
diluted with a little jojoba or almond oil, or mixed
in glass spray bottle
with a little bit of distilled water.
Home Health makes a refreshing "Lavender Water".
Another trick which works,
--ingesting garlic or brewer's yeast.

The Greeks and Romans fumigated rooms by burning thyme,
a costom that helped to repel fleas and other insects.
