Can drain flies come from the toilet?

Can drain flies lay eggs in humans?
The maggots (larvae) of some drain fly species can cause myiasis, a parasitic infestation. Although their breeding behaviour makes them potential carriers of disease causing pathogens, drain flies are not known to transmit such pathogens to humans.
How did I get drain flies?

Where do drain flies lay eggs?
The adults live for about 20 days, during which they will breed only once, often within hours of emerging from their pupal casings. Females will lay their eggs (between 30 and 100) just above the water line inside moist drains. Within 48 hours these eggs hatch into drain worms, the larval form.
