How Do Bed Worms Get in My Bed?
Bed worms can land in your bed in one of two ways: either eggs were laid in or on the bed by a mature parasite, or the worms were carried to the bed by a human or animal previously exposed to the worms or their eggs.
Fleas and bed bugs are attracted to beds because host humans spend so much time there. Bed bugs can sense a sleeping human by sensing the CO2 they exhale, while fleas can detect humans’ body heat, movements, and vibrations caused by breathing.
Carpet beetles, though not harmful to humans directly, are attracted to animal fibers, such as skin cells, silk, hair, feathers, and fur. They may also feed on plant materials, including books, grains, spices, and pet foods. If your bedding includes silk, cotton, or wool fibers, it may be an attractive breeding ground for carpet beetles.
Likewise, clothes moths are also attracted to animal fibers — only they can fly. These moths, found all over the world, might mate in your home and lay eggs in, on, or near your bedding so the larvae can have access to fibers as soon as they hatch. Once these eggs hatch, the larvae will build a small cocoon-like tunnel around their body to use as camouflage, making these pests relatively easy to spot and identify.
