WB has been treated for fleas and is still scratching. i googled for a cure incase he already had an infestation and found one that said if you bath him using washing up liquid and then spray diluted lavender oil on his coat it should get rid and keep them away. i actually put a few drops of lavender in tha bath water and washed him with the washing up liquid. i rinsd him really well and dried him as well as i could. he still scratches.
