Stomp on some ants and sing with me:

Dead ant, dead ant dead ant-ant-ant, dead ant dead ant dead ant-ant-ant, dead ant dead ant dead ant-ant-ant .... deaaaaaaaaaad ant, deaaad ant!

In case you can't tell, I HATE ANTS!!

We don't have a problem in this house, thank Heavens, but we've had troubles in other houses. I will take the chalk suggestion on board!
