Where do you live that raccoons are invasive? I had never heard of them spreading into other areas before.
Definition for invasive;
especially of plants or a disease) tending to spread prolifically and undesirably or harmfully.
I live where they DON'T BELONG, the Rockies...So, they're INVASIVE here and spread disease and wreak havoc.... All because they were "cute" "exquisite creatures"... Dirty vermin. Nobody else wants them either.
