How can laundry bedbugs be found? - briefly
Examine washed garments closely, especially seams, folds, and tags, for live bugs or their shed skins using a magnifying glass or strong light; the insects are small (≈4‑5 mm), reddish‑brown, and often hide in creases. Additionally, run a lint‑free cloth over the fabric to capture any moving specimens for further identification.
How can laundry bedbugs be found? - in detail
Detecting bedbugs that have migrated into clothing requires systematic examination of each item after washing. Visual inspection should focus on seams, folds, and pockets where insects hide. Use a magnifying lens (10×–20×) to spot live bugs, shed skins, or tiny dark spots that indicate fecal matter. Typical signs include:
- Small, reddish‑brown insects about 4–5 mm long.
- Translucent exoskeletons left after molting.
- Rust‑colored stains on fabric.
- Small white specks (eggs) attached to seams.
Temperature testing can confirm presence. Place suspect garments in a sealed bag and heat to 45 °C (113 °F) for at least 30 minutes; mortality occurs rapidly, and any surviving insects become more visible. Conversely, freezing at –20 °C (–4 °F) for 48 hours also kills bugs and makes them easier to locate.
Chemical detection methods include using a bedbug‑specific lure or attractant spray on a white cloth placed among the laundry. After a short exposure, examine the cloth for captured insects. Professional pest‑monitoring devices, such as sticky traps impregnated with pheromones, can be positioned inside dryer drums or laundry baskets to catch wandering bugs.
For large loads, employ a systematic approach: separate items by type, inspect each piece individually, and document findings. If any evidence is found, immediately isolate the contaminated garments in sealed plastic bags and subject them to high‑heat drying (≥60 °C/140 °F) for 30 minutes to ensure eradication. Repeat inspections after treatment to verify that no remnants remain.
