How does a domestic bed bug look and how can it be eliminated? - briefly
The common household bed bug is a tiny, oval, reddish‑brown insect roughly 4–5 mm long, flat when unfed and balloon‑shaped after feeding. Effective control combines thorough vacuuming, laundering of infested fabrics at high temperature, and targeted use of approved insecticides or professional heat treatment.
How does a domestic bed bug look and how can it be eliminated? - in detail
The common household bed bug is a small, wingless insect measuring 4–5 mm in length when unfed and expanding to about 7 mm after a blood meal. Its body is oval, flattened laterally, and covered with a reddish‑brown exoskeleton that darkens after feeding. The head is concealed beneath the thorax, and the antennae consist of six segments. Six legs are attached to the thorax, each ending in a claw that enables rapid movement across fabrics. Nymphs resemble adults but are lighter in color and increase in size through five molting stages, each stage requiring a blood meal.
Infestations become evident through several indicators. Live bugs may be spotted in seams of mattresses, box springs, headboards, or furniture cracks. Small, dark‑red spots on bedding are digested blood, while faint, irregular stains on sheets indicate excreted feces. A faint, sweet, musty odor may be present in heavily infested areas.
Effective eradication combines thorough inspection, mechanical removal, environmental manipulation, and targeted chemical treatment.

Inspection and isolation
-
Physical control
• Steam treatment at ≥ 100 °C applied to seams, folds, and hidden cracks.
• Cold treatment: place infested items in a freezer at ≤ ‑18 °C for a minimum of 4 days. -
Chemical control
• Apply a residual pyrethroid or neonicotinoid insecticide approved for indoor use, following label directions precisely.
• Use aerosol or dust formulations in hard‑to‑reach voids, ensuring adequate coverage without over‑application. -
Integrated approach
• Repeat the entire process after 7–10 days to target newly emerged nymphs.
• Monitor with passive interceptors placed under bed legs; replace weekly.
Professional pest‑management services may be required for extensive infestations, especially when resistance to common insecticides is suspected. Continuous vigilance and adherence to the outlined procedures are essential for long‑term suppression.
