Just curious....what do you know about lavendar & eucalyptus as flea repelents?
In the early 17th century, eucalyptus was unknown to Culpepper, whose HERBAL, is the best known book of that time dealing with herbs and their uses. Lavender was used as both as medicine and cleaner but not for a flea repellent. Fleabane was used as a flea repellent.
