I googled home remdies last week in desperation as my poor Jack Russel struggles so much and chews her back and feet raw from the resulting allergy. I find products like Frontline dont work very well and are very expensive when you have lots of pets (I have 6).
There were so many options that I just combind the ones I felt were best, and Ive had such great results. Lulu's back is already starting to clear up a week later and I havent noticed any fleas on any of my 6 animals so far.
I used the following combination:
Presoak: several lemons boiled in water with a few teaspoons of salt. Once cooled, I added vinegar to this and sprayed their coats as solidily as they would allow, then left to dry.
Wash: I mixed Johnsons baby bedtime bath or shampoo, with a dishwashing liquid and a washing powder, and lathered them thoroughly before rinsing well.
Conditioning: I mixed 300mls Johnsons baby oil with 10 drops of each of the following essential oils: lavender, grapefruit and teatree. I massaged this into their coats as much as I could.
Sprinkle: I put a line of washing powder from each dogs neck to tail once they were compltely dry. I did not do this to the cats however.
I also used the peels of the lemons from the presoak to put under their bedding to help keep the fleas out and Ive been adding apple cider vinegar to their food about 3 times a week.
Its a fair amount of work, but just make it part of your routine and keep the washing days to a sunny weekend.
Seems to work for me, so I hope it does for you!
