Seal cracks, eliminate clutter, and apply a professional‑grade insecticide or heat treatment to all infested zones. Wash all fabrics at ≥60 °C and vacuum thoroughly to remove any remaining insects.
How to get rid of outdoor bedbugs in an apartment? - in detail
Eliminating outdoor bed‑bugs that have entered a dwelling requires a systematic approach that combines inspection, containment, treatment, and prevention.
Begin with a thorough inspection. Examine seams of mattresses, box springs, headboards, and nearby furniture. Extend the search to baseboards, window frames, door thresholds, and exterior walls where insects may hide. Use a bright flashlight and a magnifying lens to spot the small, reddish‑brown insects and their dark‑colored fecal spots.
After confirming the infestation, isolate the affected area. Remove bedding, curtains, and clothing, sealing each item in a zip‑lock bag before laundering on the hottest setting the fabric can tolerate. Place the bags in a freezer for at least 72 hours if heat‑drying is not possible.
Select an appropriate treatment method:
- Heat treatment: Raise room temperature to 130 °F (54 °C) for a minimum of 90 minutes. Portable heaters and professional equipment can achieve uniform heat. Verify temperature with calibrated thermometers placed at various points.
- Chemical application: Apply a residual insecticide labeled for bed‑bug control to cracks, crevices, and baseboards. Follow label directions for concentration and safety precautions. Consider a product containing a pyrethroid combined with an insect growth regulator for added efficacy.
- Steam: Direct a high‑temperature steam (above 212 °F / 100 °C) onto hiding spots, especially seams and folds. Steam penetrates fabric and eliminates eggs as well as adults.
- Diatomaceous earth: Lightly dust non‑porous surfaces such as baseboards and behind furniture. The abrasive particles damage the insects’ exoskeletons, leading to dehydration.
After treatment, monitor the area for two weeks. Use sticky traps placed along walls and under furniture to detect any surviving insects. Repeat the chosen method if trap captures persist.
Prevent future incursions by controlling entry points. Seal cracks in exterior walls, repair damaged screens, and install door sweeps. Reduce clutter that offers hiding places, and keep outdoor vegetation trimmed away from the building’s foundation. Regularly vacuum carpets and upholstered furniture, disposing of the vacuum bag in a sealed container.
Consistent application of these steps eradicates outdoor‑origin bed‑bugs from an apartment and minimizes the risk of re‑infestation.
