What type of insect prefers to build up around pipes in bathrooms?

Silverfish are known to thrive in damp, humid environments, which makes bathrooms an ideal habitat for them. They are particularly attracted to the moisture around pipes, as well as the organic materials often found in such locations, like paper, glue, and other carbohydrates. Their presence is frequently associated with bathrooms due to the availability of moisture and dark corners where they can hide. This affinity for humidity is why silverfish are commonly found building up around water sources like plumbing fixtures.

Other insects, such as ants, termites, and moths, have different habitat preferences or nesting behaviors that do not specifically align with building up around pipes in bathrooms. Ants generally seek out food sources, termites are more inclined to infest wood structures rather than thrive in moist bathroom environments, and moths are primarily attracted to fabrics and food sources rather than plumbing areas. Thus, silverfish distinctly fit the description in question.
