Where do bedbugs on a sofa come from? - in detail
Bedbugs are typically introduced to upholstered furniture through human movement and the transport of infested items. The most common pathways include:
- Travel luggage – suitcases, backpacks, or duffel bags that have rested on an infested surface can deposit insects onto the sofa when placed nearby.
- Second‑hand furniture – sofas acquired from thrift stores, garage sales, or online marketplaces may already harbor a population if previously exposed to an infestation.
- Clothing and personal belongings – garments, blankets, or shoes that have been in contact with a contaminated environment can carry nymphs or adults that crawl onto the couch.
- Pets – dogs, cats, or other animals that have visited an infested dwelling may bring bedbugs on their fur or in their bedding, later shedding them onto the furniture.
- Visitors – guests staying in a home with an active problem can unintentionally transfer insects on their belongings or bodies.
Bedbugs locate a sofa by detecting carbon dioxide, heat, and the scent of a sleeping host. Once on the upholstery, they hide in seams, folds, and the fabric backing, where they are protected from disturbance. Repeated exposure to any of the listed vectors increases the likelihood that a sofa will become a harbor for these pests. Regular inspection of seams, removal of clutter, and careful handling of second‑hand items are essential preventive measures.
