Bedbugs have infested the mattress, what should be done? - briefly
First, strip the bed, wash all linens at ≥120 °F, vacuum the mattress thoroughly, and install a certified encasement. Next, engage a licensed pest‑control professional to treat the infestation and prevent recurrence.
Bedbugs have infested the mattress, what should be done? - in detail
A mattress that is hosting bed‑bug colonies requires immediate, systematic action to eradicate the insects and prevent re‑infestation.
First, isolate the sleeping area. Remove all bedding, clothing, and nearby fabrics. Place these items in sealed plastic bags to avoid spreading insects to other rooms.
Next, treat the linens and clothing. Wash at 60 °C (140 °F) or higher for at least 30 minutes; dry on the hottest setting for a minimum of 30 minutes. Items that cannot withstand heat should be sealed in bags for 90 days, the period needed for bed‑bug eggs to hatch and die.
Then, address the mattress itself:
- Vacuum the entire surface, seams, and crevices with a HEPA‑rated vacuum. Immediately empty the canister into a sealed bag and discard.
- Apply a high‑temperature method: use a steam cleaner producing at least 100 °C (212 °F) steam, moving slowly to ensure penetration into folds and stitching. Alternatively, use a portable heater or a professional heat‑treatment chamber that raises the mattress temperature to 50–60 °C (122–140 °F) for several hours.
- Encase the mattress and box‑spring in a certified, zippered bed‑bug encasement. Keep the encasement on for at least one year, checking regularly for signs of activity.
If chemical control is required, follow these guidelines:
- Select an EPA‑registered insecticide labeled for bed‑bugs, preferably a product containing a pyrethroid combined with a desiccant or a neonicotinoid. Apply according to label directions, targeting cracks, tufts, and the mattress underside.
- Use a dust formulation (e.g., silica‑based) in voids where spray may not reach. Avoid over‑application, which can cause resistance.
Professional extermination should be considered when:
- Infestation is extensive or persists after initial measures.
- Structural cracks, baseboards, or furniture provide hidden refuge.
- The resident prefers a guaranteed, monitored approach.
After treatment, implement ongoing monitoring:
- Place interceptor traps under each leg of the bed to capture any surviving bugs.
- Conduct weekly visual inspections of the mattress seams, headboard, and surrounding furniture.
- Maintain low clutter and regular vacuuming to reduce harborages.
Prevention for future protection includes:
- Inspect second‑hand furniture before bringing it indoors.
- Use protective mattress encasements continuously.
- Wash and dry bedding weekly on high heat.
- Seal cracks in walls, baseboards, and floorboards with caulk.
By following these steps—isolating the area, laundering and heat‑treating fabrics, thoroughly cleaning and encasing the mattress, applying targeted insecticides when necessary, and employing professional services if needed—complete eradication can be achieved and the risk of recurrence minimized.
