How can you kill bedbug eggs? - briefly
Expose infested materials to temperatures above 120 °F (49 °C) for at least 30 minutes, which kills both adults and eggs. Alternatively, apply an EPA‑registered insecticide labeled for egg control, following the product’s instructions precisely.
How can you kill bedbug eggs? - in detail
Eliminating bed‑bug ova requires methods that penetrate the protective chorion and disrupt embryonic development. Chemical approaches include:
- Heat treatment: Raise ambient temperature to 122 °F (50 °C) for at least 90 minutes. Heat destroys eggs regardless of their location, provided the temperature is uniform.
- Steam: Direct steam at 212 °F (100 °C) for 30 seconds per spot. The immediate exposure kills eggs on surfaces, mattresses, and crevices.
- Cold exposure: Maintain temperatures at 0 °F (‑18 °C) for a minimum of four days. Freezing interferes with cellular processes, leading to egg mortality.
- Insecticide sprays: Apply products labeled for egg control, containing pyrethroids, neonicotinoids, or desiccants such as diatomaceous earth. Ensure thorough coverage of seams, folds, and hidden voids where eggs are likely deposited.
- Silica‑based powders: Distribute fine silica dust in cracks and bedding. The abrasive particles abrade the egg shell, causing desiccation.
Physical measures complement chemicals:
- Vacuuming: Use a high‑efficiency vacuum with a HEPA filter. Run the hose over all suspect areas for several minutes, then seal and discard the bag or container.
- Mattress encasement: Install zippered covers certified to trap and starve eggs. Leave the encasement on for at least one year to ensure any surviving eggs hatch and are unable to re‑infest.
- Laundering: Wash infested fabrics in hot water (≥130 °F or 54 °C) and tumble‑dry on high heat for 30 minutes. Heat penetrates fabric layers and eradicates eggs.
Integrated pest management (IPM) combines these tactics. Begin with a thorough inspection, then apply heat or steam to the entire infested zone. Follow with targeted insecticide or silica applications in hard‑to‑reach spots. Finish with vacuuming, laundering, and encasement to prevent re‑emergence. Monitoring traps placed after treatment confirm the success of egg eradication.
