“What are these worms and should we be worried?” asks this reader, who is worried that the worms are inside her and the people who have used the toilet. The creature, who was found “swimming in [her] toilet”, seems to be a dark-brown color, with a brighter, yellowish tail/head (though it is difficult to tell).

Small, dark brown worms of about 0.6cm (roughly 0.2-inches) have been popping up in the bathrooms and kitchen of this reader’s townhouse. Our reader tends to find multiple at a time in the kitchen, but only one at a time in the bathroom, and has been finding these worms for about a year now.
