Honestly I am not a fan of DE. Its very drying for the skin and can cause Respiratory issues. No5 much proof it works. Feeding it is usless and if it gets wet topical or ground treatment it also voids effectiveness.
If you are not seeing lice, just scratchy, check his skin to see if hes dried out..maybe needs some helathy fat in his diet. I like using coconut oil with flax seed and wheat germ mixed in. A tablespoon of that a few times a day for a week or so seems to help. Or a drizzle of a quality Ex virgin olive oil. Other causes can be zinc or copper deficiency....
If at closer examination you do find lice..Cylence works well. If you prefer natural treatment, feeding fresh raw garlic helps and petting him with a quality te tree ess oil diluted with carrier oil.
Best wishes
