Since it has been getting cooler in Oklahoma, I have been getting these red/pink larvae looking creatures on my tile floors. They are fat and close to the size of my pinky finger. So far, I have found 7 lying in different rooms in my house. I do not have pets, so it couldn't be dog/cat food that is bringing them inside. They are becoming a problem because I freak out every time I see one. I refuse to allow them to live with me and quickly send them packing when I run across one.

Those are some big worms. Post a picture for a better answer.
