Anyone know of a good Copperhead repellent? I just killed a full grown Copperhead by my back door. Not a good place to find a poisonous snake. Not to mention that I have little kids (6 and 9 years old) who play out there. I would like to stick with natural stuff, but I've heard that mothballs work. I'll try that first. Anyone know of anything else? Also, I have 2 dogs (large) and 4 outside cats, but my 9 year old daughter spotted it first.
