The holes in the horn look like bettle/bug damage to me as well (Fearns silverfish sound like tough little customers, the ones I rarely see here are cute and about 1cm long).
The only real option for that damage is to mix up a little resin based filler of similar colour and fill the holes in. They aren't very big, it'll work OK.
Have a look round a car boot sale and buy something made from black buffalo horn and use a rough file to grind off a kind of chunky dust and mix it with a little black wood stain and epoxy then spatula it in and smooth it off. When it's dry polish it with fine sandpaper and it'll look much better. Not invisible, but better than holes.

Salaams Atlantia~ Thoroughly great advice there on the restoration of the hilt ... Shukran... Ibrahiim.
