What do bedbugs fear in the apartment and how to get rid of them in the apartment? - briefly
Bedbugs are repelled by extreme heat, desiccating agents such as diatomaceous earth, and correctly applied insecticide sprays. Effective eradication combines thorough heat treatment (above 45 °C) with targeted chemical applications and sealing of cracks and crevices.
What do bedbugs fear in the apartment and how to get rid of them in the apartment? - in detail
Bed bugs are highly sensitive to extreme temperatures. Exposure to sustained heat above 45 °C (113 °F) for several minutes kills all life stages, while prolonged cold below –17 °C (1 °F) also proves lethal. Their thin exoskeleton makes them vulnerable to rapid desiccation; low‑humidity environments (relative humidity under 30 %) accelerate water loss and lead to mortality. Certain chemical compounds—particularly pyrethroids, neonicotinoids, and desiccant powders such as diatomaceous earth—disrupt their nervous system or damage the cuticle, causing death. Natural predators, including the rove beetle Staphylinidae and certain mites, can suppress populations, though they are rarely present in residential settings.
Effective eradication follows a systematic approach:
- Conduct a thorough visual inspection, focusing on seams of mattresses, box springs, bed frames, headboards, baseboards, and cracks in furniture.
- Remove and launder all linens, clothing, and washable fabrics at temperatures of at least 60 °C (140 °F); dry‑clean items that cannot be washed.
- Vacuum all surfaces, paying special attention to crevices; immediately discard the vacuum bag or seal the canister.
- Apply heat treatment to infested items using a portable steamer (minimum 100 °C / 212 °F) or professional whole‑room heating equipment, maintaining target temperature for a minimum of 30 minutes.
- Distribute a calibrated amount of desiccant powder in hidden cracks, under furniture, and along baseboards; leave in place for several days before re‑vacuuming.
- Seal mattresses and box springs with certified encasements, ensuring zip closures are intact; keep encasements on for at least one year to prevent re‑infestation.
- Install interceptors on bed legs to monitor and capture migrating insects.
- If chemical control is warranted, apply a residual insecticide labeled for bed‑bug use to voids, cracks, and baseboards, following manufacturer safety guidelines.
- Engage a licensed pest‑management professional for integrated pest‑management strategies, especially in severe or multi‑unit infestations.
Consistent monitoring after treatment, combined with preventive measures—regular laundering, reduced clutter, and maintenance of low‑humidity conditions—prevents resurgence and ensures long‑term control.
