What were bed bugs traditionally treated with? - briefly
Traditional control used heat, steam, and early insecticides such as pyrethrum and DDT, complemented by natural repellents like cedar, tobacco smoke, and essential oils. Physical measures—including thorough washing, vacuuming, and sunlight exposure—were also employed.

Historical control of Cimex lectularius relied on a limited arsenal of natural and chemical agents. Early societies employed botanical extracts, such as the essential oils of lavender, rosemary, and pennyroyal, applied to bedding or used in sachets. These aromatics possessed insecticidal or repellent properties, although efficacy varied with concentration and exposure time.
In medieval Europe, powdered sulfur and quicklime were scattered on mattress frames and floorboards. Sulfur generated toxic fumes when heated, while quicklime raised pH levels, creating an inhospitable environment for the insects. Both substances required careful handling to avoid damage to fabrics and respiratory irritation.
The 19th century introduced inorganic insecticides, notably arsenic trioxide and mercuric chloride, dissolved in water and sprayed onto sleeping surfaces. These poisons killed bed bugs on contact but posed severe health risks to occupants, prompting eventual regulation.
From the late 1800s onward, petroleum‑based preparations, such as kerosene and later petroleum distillates, were poured onto infested areas. The liquids suffocated insects and disrupted their cuticular waxes. Application demanded thorough ventilation to prevent fire hazards.
In the early 20th century, synthetic pyrethrins derived from chrysanthemum flowers entered the market. Formulated as powders or liquids, they offered rapid knock‑down effects with lower mammalian toxicity compared to earlier heavy metals.
Traditional treatments thus progressed from aromatic herbs and mineral powders to toxic metal salts, petroleum products, and finally to naturally derived synthetic insecticides, each reflecting the prevailing scientific understanding and available resources of its era.
