Etymology 1

/tani/ → /dani/

From Old Japanese. Shift from earlier reading tani.[1][2] This reading persists in some modern dialects.

The kanji spelling is unrelated to the reading, and appears to be a case of semantic ateji or jukujikun. The characters literally mean 壁 (“wall”) + 蝨 (“louse”), possibly as an indication that ticks and mites may be found on walls.
