How can you remove bedbugs from a mattress yourself? - briefly
Isolate the mattress and apply high‑heat treatment—use a dryer on the hottest setting or a steam cleaner for a minimum of 30 minutes. Then spray a bed‑bug‑approved insecticide on seams and folds, and repeat the application after seven days to eliminate any remaining insects.

How can you remove bedbugs from a mattress yourself? - in detail
Begin by confirming the presence of insects. Look for live bugs, shed skins, or small reddish‑brown spots on the mattress surface and seams. Use a bright flashlight and a magnifying glass to improve detection.

Isolate the sleeping area

Remove all bedding, pillows, and mattress‑top covers.
Wash linens in hot water (≥ 60 °C) and dry on the highest dryer setting for at least 30 minutes.
Place clean items in sealed plastic bags until treatment is complete.

Apply heat

Set a household dryer to the highest temperature and run the mattress cover (if removable) for 30 minutes.
For the mattress itself, use a portable steam cleaner that reaches ≥ 100 °C. Pass the steam head slowly over every surface, paying special attention to seams, tufts, and folds. Keep the steam nozzle within a few centimeters of the fabric to ensure penetration.

Vacuum thoroughly

Use a vacuum equipped with a HEPA filter.
Move the nozzle slowly across the entire mattress, focusing on stitching, edges, and the underside.
After each pass, empty the vacuum canister into a sealed bag and discard it outdoors.

Apply a residual insecticide (optional)

Choose a product labeled for bedbug control on fabrics, such as a pyrethroid‑based spray or a silica‑dust formulation.
Follow the manufacturer’s dosage instructions precisely.
Spray lightly, covering seams, tufts, and the mattress perimeter. Allow the product to dry completely before re‑covering.

Encasement

Install a zippered mattress encasement that is certified bedbug‑proof.
Ensure the cover fully encloses the mattress and is sealed without gaps.
Keep the encasement on for at least 12 months; any surviving insects will die inside without a food source.

Monitor and repeat

Place interceptors or sticky traps under each leg of the bed to capture wandering bugs.
Inspect the mattress and surrounding area weekly for three months.
Repeat the steam and vacuum steps if new signs appear.

By following these actions—inspection, heat treatment, thorough vacuuming, targeted insecticide use, protective encasement, and ongoing monitoring—you can eradicate bedbugs from a mattress without professional assistance.
