“Can you identify this as a worm and if so, what species?” asks Kim about the gooey, strand of matter pictured below. “I picked it up, put it in a container and soaked it in tea tree oil to hopefully kill it if it was a living thing. Have found these on the floor in my Central Florida mobile home that has a well and that has had some stopped-up septic problems and overflows. Could either be the cause? I will also add that we are in a rural area and we have, or have had in the past, cats, dogs, donkeys, cows, goats, pigs, chickens, and rabbits; we fed out a wild boar twice. I would like to know your opinion on the type of whatever this may be, and maybe even the potential host if it is a parasite so I can pinpoint the area and treat it and the tenant on its rented acre of land. We are in a wooded area of twelve acres. Don’t know if it was carried in the home or, like I mentioned, a result of the septic issue. The other “samples” looked like they could have been stepped on. Oh, and I should mention that my cat stares at the floor because she can see something we cannot. She refuses to walk in certain areas and bolts through, jumping as fast and far as her pudgy little self can go, to avoid these spaces. I have sent as many photos as I have and tried to take different vantage points for you. Thanks again for your considerable help.”
