We think the worms our reader has discovered in her home are probably earthworms. If our reader is concerned about her son’s health or worried that the worm she found in his bed came from him, then we recommend that she take him to the doctor immediately.
One of our readers asked about the impact of “thin black worms with many legs” on her plants. We believe she is probably dealing with millipedes, and that she shouldn’t worry because they are typically beneficial.
We aren’t able to identify the specimen our reader found in his laundry room. We don’t think it is related to his pets or a parasitic organism. If any of our readers recognize this creature we invite them to comment below!
