What is the name of a plant that smells like bed bugs? - in detail

Coriander (Coriandrum sativum) is the herb most commonly identified as emitting a scent comparable to that of Cimex species. The plant belongs to the Apiaceae family, is cultivated as an annual herb, and is valued for both its leaves and seeds.

The similarity arises from overlapping volatile compounds. Essential oil extracted from coriander leaves and seeds contains high concentrations of linalool, α‑pinene, and (E)-2‑hexenal. Bed‑bug aggregation pheromones also feature these aldehydes and terpenes, producing a sweet‑musty aroma that many describe as “coriander‑like.” Laboratory assays have demonstrated that the odor profile of coriander extracts can attract or repel bed bugs, confirming the chemical correspondence.

Botanical details

  • Growth habit: erect herb, 30–50 cm tall, hollow stems.
  • Leaf morphology: finely divided, feathery, aromatic when bruised.
  • Seed characteristics: small, round, brown, rich in essential oil (≈0.5 % by weight).

Cultivation notes

  • Soil: well‑drained, neutral to slightly acidic.
  • Sunlight: full sun to partial shade.
  • Harvest: leaves cut before flowering for maximum flavor; seeds collected after pods mature.

Uses relevant to the odor discussion

  • Culinary: leaves and seeds as flavoring agents.
  • Aromatherapy: oil employed for its fresh, citrus‑herbaceous scent.
  • Entomology: coriander oil tested as a component of bait or repellent formulations targeting bed‑bug populations.

In summary, coriander’s volatile composition aligns closely with the characteristic odor of bed bugs, making it the plant most frequently cited for this resemblance.
