What damage do centipedes and millipedes typically cause in homes?

Centipedes and millipedes generally do not cause significant damage to structures or belongings in homes. They are primarily scavengers and feed on decaying organic matter, such as dead insects and plant material, which means they don't pose a direct threat to furniture or structures. While their presence might be undesirable, they are not known for causing harm like termites or carpenter ants, which actively damage wood and other materials in homes. Therefore, it is accurate to state that these creatures typically cause no meaningful damage to homes or the items within them.

The other choices reflect scenarios that do not associate with the behavior and characteristics of centipedes and millipedes. For instance, they do not typically affect human health through allergies, nor do they contribute to structural damage, making the idea that they cause any significant issues in residences misleading.
