[Cluesless]

The cells that line the nose have tiny hairs on them, they collect and trap a lot of dirt and "stuff" when u breath in-- this eventually builds up and Le Voila-- Boggies! Might be some sort of bodily secretion invoved too but most of it is the filterd "stuff"

[WaldoMcFroog]

Mucus is produced by the nasal lining, and is there to catch any alien objects in a breath of air, and the hairs, as the previous correspondant said, act as trap.
