How to determine the presence of bedbugs in bedding? - briefly
Examine seams, folds, and tags with a flashlight and magnifier for live bugs, shed exoskeletons, or small dark spots, and place disposable interceptor traps beneath the mattress. If any evidence is found, verify the infestation with a professional pest‑inspection service.
How to determine the presence of bedbugs in bedding? - in detail
Detecting an infestation in sheets and mattress covers requires systematic observation and targeted tools.
First, examine the sleeping surface during daylight. Look for small, reddish‑brown spots that are about the size of a pinhead. These are excrement stains, often found near seams, folds, and the edges of the mattress. Also check for faint, rust‑colored lines, which indicate where an adult has been crushed.
Second, search for live insects. Adult bed bugs are oval, flat, and measure 4–5 mm. They hide in creases, under pillowcases, and inside the stitching of duvet covers. Use a bright flashlight to illuminate tight spaces; a magnifying lens can aid identification of the characteristic “shield‑shaped” body.
Third, inspect the surrounding environment. Bed bugs leave shed skins (exuviae) that appear as translucent, hollow shells. Collect any found shells and compare them to reference images for confirmation.
Fourth, employ passive monitoring devices. Place interceptor cups beneath each leg of the bed; the cups contain a smooth inner surface that prevents insects from climbing back up, allowing you to capture any that wander onto the frame. Sticky traps positioned along the headboard and footboard can also reveal activity.
Fifth, consider chemical detection. Bed bug pheromone lure strips, placed between sheets, attract insects and provide visual evidence when the strip shows a trace of blackened insects or fecal spots.
Finally, document findings. Photograph each sign, note its location, and record the date. This record assists professionals in assessing the severity of the problem and guides treatment decisions.
By following these steps—visual inspection, identification of excrement and shed skins, use of interceptors and traps, and careful documentation—you can reliably determine whether bed bugs are present in your bedding.
