There's no need to commit a huge force to destroy the Numidians. After wiping out the Carthaginian presence in Africa, take and exterminate Cirta and Tingi, while wiping out the huge Numidian armies usually present in the area. The southern part of Africa in the game is usually deserted and easily taken by a few units of equites recruited from Carthage, which gives you a few general promotions as well.
