What is a bed worm?

As an AI language model, I could not find any relevant information about a "bed worm". However, there are some common pests that are associated with beds like bed bugs, dust mites, and carpet beetles. Bed bugs are small, reddish-brown insects that feed on human blood and can cause itchy bites. Dust mites are microscopic creatures that thrive on dust in bedding and mattresses, and they can cause respiratory problems. Carpet beetles can cause damage to carpets, furniture, and clothing, and their larvae can sometimes be found on or near beds. It is important to keep your sleeping areas clean and free from pests to ensure a good night's sleep and to prevent health hazards.
