Do Ants Have Noses?

My granddaughter F noticed that ants always come in her room when it rains and they seem to "find food crumbs" on the carpet. She said, "It really bugs me." "Grandma, do ants have noses?" I tried to explain the antennae to her, but she didn't believe it.
Then, she was talking to my husband about school (he's in chiropractic college) and he told her he had to study for a test. She said she hated tests and that "You need to finish school and bring Grandma back here." "You're too old for school." "Grandma has a job to do here." He asked her what grandma's job is to do and she said, "To love little kids!"
