Which folk remedies can help get rid of bedbugs at home? - briefly
Several traditional treatments—diatomaceous earth, essential‑oil sprays (e.g., tea tree or lavender), and high‑temperature exposure—can reduce bedbug populations when applied correctly. Consistent use combined with thorough cleaning maximizes effectiveness.
Which folk remedies can help get rid of bedbugs at home? - in detail
Traditional approaches for eliminating bedbugs without chemical insecticides rely on physical disruption, environmental modification, and natural substances. Effectiveness depends on thorough application, repeated cycles, and integration with preventive measures such as mattress encasements and clutter reduction.
-
Heat exposure – Raising room temperature to ≥ 50 °C (122 °F) for several hours kills all life stages. Portable steam generators can treat seams, folds, and crevices; steam must reach a minimum of 100 °C at the point of contact and remain on the surface for at least 30 seconds.
-
Cold treatment – Exposing infested items to temperatures below ‑20 °C (‑4 °F) for a minimum of 72 hours eliminates bedbugs. Freezer compartments of household refrigerators are unsuitable; a dedicated freezer or outdoor exposure during winter is required.
-
Diatomaceous earth – Food‑grade silica particles abrade the insect exoskeleton, causing desiccation. Apply a thin, even layer to mattress edges, baseboards, and behind furniture. Reapply after vacuuming or cleaning, as moisture reduces efficacy.
-
Baking soda – Similar to diatomaceous earth, sodium bicarbonate absorbs lipids from the cuticle. Sprinkle lightly on affected areas, leave for 24 hours, then vacuum. Results are modest; combine with other methods for greater impact.
-
Essential oil blends – Certain volatile oils possess repellent or toxic properties. A mixture of « lavender », « tea tree », and « neem » oils, diluted to 5 % in water, can be sprayed onto bedding and cracks. Direct contact may irritate the insects, while the scent deters new infestations. Use caution on fabrics that may stain.
-
Alcohol solutions – Isopropyl alcohol (70 % concentration) penetrates the cuticle and causes rapid dehydration. Apply with a spray bottle to visible bugs and their hiding places; avoid over‑saturation, which can damage finishes and increase fire risk.
-
Soap‑water rinse – A solution of liquid dish soap (2 % v/v) and warm water disrupts the protective wax layer. Use a cloth or spray to treat surfaces where bugs congregate. This method is most effective when combined with heat or vacuuming.
-
Vacuum extraction – High‑efficiency vacuum cleaners equipped with HEPA filters remove live insects and eggs from mattresses, box springs, and furniture. Immediately seal the vacuum bag or canister in a plastic bag and discard in an outdoor trash receptacle.
-
Mattress encasement – Though not a folk remedy per se, encasing the mattress and box spring in a zippered, bedbug‑proof cover traps any remaining insects and prevents re‑infestation. Leave the encasement on for at least 12 months to ensure all life stages expire.
Successful eradication requires rotating these techniques, monitoring with sticky traps, and maintaining cleanliness. Repetition over several weeks eliminates hidden eggs and reduces the population to zero.
