Do you have any other pics of a pinworm? We had a pretty good rain storm this past Wed. and the next day I found a bunch of pinkish tan very small worms crawling about my concrete patio. They appeared to have come from the lawn. I have never seen them before,and I am not sure what they are or even if I should be concerned about them. I have a feral cat colony also two dogs who live indoors. I am worried for their safety.
