Bed bug infestations are primarily the result of two species of insects from genus Cimex: Cimex lectularius (the common bed bug) and Cimex hemipterus.[3] These insects feed exclusively on blood and may survive a year without eating.[3] Adult Cimex are light brown to reddish-brown, flat, oval, and have no hind wings. The front wings are vestigial and reduced to pad-like structures. Adults grow to 4–5 mm (0.16–0.20 in) long and 1.5–3 mm (0.059–0.118 in) wide.
Apply residual Bed Bug Insecticide Spray. After every crack, crevice, switch plate, electrical switch, baseboard, box springs, mattress, etc, has been treated and everything is put back, it is time for the residual treatment. Using a hand held sprayer such as the Chapin Sure Spray apply Optimate, Cy-Kick, Suspend SC or Demand along the baseboards in the bedroom and closet, under and around the bed, behind the headboard, inside bed stands etc.
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
