They show up everywhere. Have been seeing these nasty, maybe 1 in. brown worms in our house and am wondering if it's dangerous for our dog and if we need to call a bug guy of some sort to get rid of them. HELP!

Have you noticed if they morph into anything else, like a small moth ?

Do they have legs? Millipedes look very similar to worms with a "fringe" of legs.
