Thank you to all who had answers to my question. I've had mice before & I think thats probably what it is. My husband is bringing d-con home tonight. Don't worry, I only have a 15 yr old son who hates the basement, he thinks its creepy & never goes down there. My dog is a boxer & because of her size cannot get in small places. But I put the poison up on a dirt bank where nothing but those nasty little rodents can get to it. Gaye E TN z6 Gaye Stanton wrote: > > a month ago.
