In the townhouse I live in we are ajoined to another building. The next door neighbor had mice to lodge under her side, so when she put down pestiside it killed them, but the odor was awful. So someone suggested I put mothballs in my vents, but I can't get the smell to leave, I need help! my boyfriend say's he can't wear anything good to my place or he leaves smelling like mothballs. So do I! can you help?
