Bed bug bites are caused primarily by two species of the insect Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] Their size ranges between 1 and 7 mm.[7] They spread by crawling between nearby locations or by being carried within personal items.[2] Infestation is rarely due to a lack of hygiene but is more common in high-density areas.[8][2] Diagnosis involves both finding the bugs and the occurrence of compatible symptoms.[5] Bed bugs spend much of their time in dark, hidden locations like mattress seams or cracks in the wall.[2]
The journal Insects published a study on products containing essential oils for bed bug control. It was found that essential oils like cedar oil, cinnamon oil, clove oil, peppermint oil, rosemary oil, and lemongrass oil all have insecticidal properties against bed bug populations. The study concluded that using these essential oils in a bug spray can be an effective way to reduce bed bug populations without putting humans at risk of exposure to chemicals.8
