What to do with wormwood for bedbugs? - briefly

Apply dried wormwood or its essential oil to cracks, seams, and bedding; the potent aroma acts as a repellent and can kill bedbugs on contact. After 24‑48 hours, vacuum thoroughly and launder fabrics to remove dead insects and residue.

What to do with wormwood for bedbugs? - in detail

Wormwood (Artemisia absinthium) contains volatile oils and bitter compounds that are toxic to many insects, including Cimex lectularius. When applied correctly, it can reduce bed‑bug populations on infested surfaces.

To employ wormwood effectively, follow these steps:

  • Preparation of a spray solution

    1. Measure 30 g of dried wormwood leaves.
    2. Combine with 1 L of hot water (approximately 80 °C).
    3. Steep for 15 minutes, then strain through a fine mesh.
    4. Add 5 ml of ethanol or isopropyl alcohol to improve penetration and prevent rapid evaporation.
    5. Transfer the mixture to a spray bottle, shaking before each use.
  • Application

    • Spray the solution onto mattress seams, box‑spring corners, bed frames, and any crevices where insects hide.
    • Apply a thin, even coating; excess liquid may stain fabrics.
    • Repeat every 48 hours for a minimum of two weeks, as bed‑bug eggs require multiple exposures to achieve mortality.
  • Alternative: Powdered form

    1. Grind dried wormwood to a fine powder (particle size < 250 µm).
    2. Lightly dust the powder onto cracks, baseboards, and under furniture.
    3. Use a hand‑held duster or brush to distribute evenly.
    4. Vacuum the area after 24 hours to remove residual plant material and dead insects.
  • Safety and precautions

    • Wear gloves and a mask when handling powder to avoid respiratory irritation.
    • Test the liquid spray on an inconspicuous fabric patch to check for discoloration.
    • Keep children and pets away from treated zones until the surface is dry.
  • Integration with other control measures

    • Combine wormwood treatment with heat exposure (temperature ≥ 50 °C) for heavily infested items.
    • Use mattress encasements to trap surviving insects and prevent re‑infestation.
    • Seal cracks and crevices to limit hiding places, enhancing the efficacy of the botanical agent.

Research indicates that wormwood’s thujone and camphor components disrupt the nervous system of bed bugs, leading to paralysis and death. However, it does not replace professional extermination when infestations are severe; it serves as a supplementary, low‑toxicity option for ongoing management.
