Which pest is often not associated with any notable damage in homes?

Millipedes and centipedes are often not associated with significant damage in homes despite being considered pests. Millipedes typically feed primarily on decaying organic matter and are not harmful to structures or living spaces. They may invade homes in large numbers, especially in moist environments, but they do not cause damage to wood or other materials, nor do they bite or pose health risks.

Centipedes, on the other hand, may enter homes seeking shelter but primarily feed on insects and other pests. While they can give a painful bite if provoked, their presence does not typically correlate with structural damage or infestations that would result in notable damage.

Springtails are different; they can become a nuisance in damp areas, but they do not cause structural damage. However, considering the context of the question, millipedes and centipedes are both notable for their lack of association with damage in homes, reinforcing the idea that both of these pests fit the criteria outlined in the question. Therefore, recognizing both millipedes and centipedes as pests that do not typically cause damage leads to the conclusion that the correct answer includes both of these options.
