Re: Red worm in toilet

I could not see anything on the link but these are most likely free living worms - anneleda (earthworms) or if they have legs, millipedes or centipedes. Check the toilet bowel seal where it connects to the sewer line, it may need to be replaced or there may be a break in the sewer line leading to the cesspool. They could be dropping in after crawling up the toilet or from the ceiling. Check for cracks in the flooring.
