One of the many uses of tea tree oil around the house is to use it as a DIY natural bed bug spray. Tea tree oil contains compounds that have an insecticidal effect against insects as well as their larvae and eggs. Although no direct studies have been published on the effect of tea tree oil on bed bugs, research has shown that it has a lethal effect on many bugs and insects.
Dust every crack and crevice. Every crack and crevice, electrical switch plate, wall switch - EVERYTHING - within 10 to 15 feet of the bed should be treated, particularly those closest to the bed. Use the "running method" of moving the application tip along the length of the crack. Look for cracks from the ground level to the ceiling as you treat each section of the room. Use Cimexa Dust or Delta Dust. If you make a mess, simply wipe it up. To much insecticide is better than too little for bed bug control.
First up are the contact sprays, like STERI-FAB and JT Eaton Kills Bed Bugs. These will kill quickly, but evaporate shortly after, leaving no long-lasting protection. Spray along baseboards, below drawers and on drawer slides, behind cabinets, and behind night stands. Follow up with a residual spray, such as Bedlam Plus and JT Eaton Kills Bed Bugs Plus. Residual sprays will offer long-lasting protection against bed bugs and hatchlings. Bedlam Plus is ideal for cracks and crevices throughout the room, while JT Eaton Plus can be used below the cushions and bases of sofas, chairs, edges of carpets and other fabric items.
To treat an allergic reaction, the doctor may prescribe an antihistamine, corticosteroid, or epinephrine injection. If the area is infected, he or she might prescribe an antibiotic or recommend an over-the-counter antiseptic. Finally, if it’s severe itchiness that you’re dealing with, applying corticosteroid or taking an antihistamine in pill or liquid form may be able to help.
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
