Who can live in a bed besides bed bugs? - briefly
A bed can accommodate humans—adults, children, infants—and domestic pets like cats or dogs. These occupants share the space intentionally, unlike parasitic insects.
Who can live in a bed besides bed bugs? - in detail
Various organisms can occupy a mattress in addition to the well‑known pests. The most common are microscopic arthropods and microorganisms that thrive in the warm, humid environment created by human occupancy.
Dust mites (Dermatophagoides spp.) are tiny arachnids that feed on shed skin cells. They proliferate in humidity levels above 50 % and can reach densities of several thousand per gram of fabric. Their presence contributes to allergic reactions and asthma.
Fleas (Ctenocephalides spp.) may seek refuge in bedding when hosts are present. Adult fleas lay eggs that fall onto the mattress, where larvae develop on organic debris. Flea infestations often accompany pet ownership.
Lice, particularly body lice (Pediculus humanus corporis), can temporarily reside in clothing and bedding, feeding on blood and laying eggs on fabric fibers. Their survival is limited to a few days without a host.
Mold and fungi, such as Aspergillus and Penicillium species, grow on damp mattress surfaces. They produce spores that become airborne, potentially causing respiratory irritation. Mold growth is accelerated by spills, sweat, or inadequate ventilation.
Bacteria, including Staphylococcus aureus and Streptococcus spp., colonize the skin and can be transferred to bedding. While most strains are harmless, pathogenic variants may cause skin infections if the mattress is not regularly cleaned.
Skin flakes, hair, and bodily fluids accumulate nightly, providing nutrients for the aforementioned organisms. Over time, these organic deposits create a micro‑ecosystem that supports a diverse community.
To minimize unwanted inhabitants, maintain mattress humidity below 50 %, wash bedding weekly in hot water, vacuum the mattress surface regularly, and replace or rotate the mattress according to manufacturer recommendations.
