I stopped by and talked to the lady I work for yesterday, She knew the name of the ant but I cant remember started with an F (no not that one) anyway she said they were not normal inside ants and that they do not eat stuff in your house, their food is outside, and that there is probably some sort of a weather condition that caused them to move inside. It is just getting them to stay out. hope this helps. Or at least makes you feel better that it is just a fluke that they got in you bedroom.
