Bed Bugs: Causes, Prevention, and Treatment

Bed bugs (Cimex lectularius) are small, blood‑feeding insects that infest homes regardless of cleanliness. They hitchhike on luggage, furniture, clothing, and used items.

How Infestations Start

• Travel (hotels, public transit)
• Secondhand furniture/mattresses
• Visitors or shared laundry facilities
• Adjacent units in multi‑unit buildings

Signs

• Itchy, red bites often in lines/clusters (face, neck, arms, legs)
• Blood spots on sheets
• Dark fecal stains on mattress seams
• Shed exoskeletons, live bugs in crevices

Prevention

• Inspect hotel rooms; keep luggage off floor/bed.
• Wash/dry clothes on high heat after travel.
• Encase mattress/box spring in bed‑bug‑proof covers.
• Reduce clutter; vacuum frequently.

Treatment

• Professional extermination (heat treatment, targeted insecticides) is most effective.
• DIY: thorough vacuuming, steam cleaning, diatomaceous earth, laundering all fabrics on high heat.
• Multiple treatments usually needed; follow‑up inspections essential.

Bed bugs don’t transmit disease but cause distress, insomnia, and secondary infections from scratching. Early detection and professional help are key.
