You are correct about using alcohol. I used straight alcohol in a spray bottle. You can’t just spray and expect it to work. The alcohol has to be sprayed ON THE BUGS in order to kill them. It must be repeated periodically in order to kill them with any affect on the population. Also they hide in cracks and crevices in your walls, and places like wallsockets, baseboards, gaps in wooden furniture like headboards. Basically anywhere they can fit. Their eggs look like little TINY clear crystals. If you are not sure if the bugs are bed bugs… squash one. They smell like black walnuts (to me anyway). I’ve read they only lay 1 egg at a time, but can lay up to 5 a day… that’s 40 in a week. So if you have them, spray OFTEN, but do not smoke or use any open flames (candles, etc…) at the same time. Alcohol is very flammable!!!
Bed bugs were mentioned in ancient Greece as early as 400 BC, and were later mentioned by Aristotle. Pliny's Natural History, first published circa AD 77 in Rome, claimed bed bugs had medicinal value in treating ailments such as snake bites and ear infections. (Belief in the medicinal use of bed bugs persisted until at least the 18th century, when Guettard recommended their use in the treatment of hysteria.[51])
When bed bugs are suspected, sleeping and resting places should be thoroughly inspected. Check all possible hiding places, mindful that bed bugs, especially the young nymphs and eggs, can fit into very tiny cracks and crevices. Don’t overlook places where pets rest, and where bats or birds have entered structures. In these instances, bat or bird bugs, not bed bugs, may be present. If bats or birds are a source of infestation, they should be excluded from the premises. Note that bats and most bird species are protected by law and should not be killed. Contact the Illinois Department of Natural Resources for guidelines on bat or bird exclusion and removal.
The type of reaction provoked depends on previous exposure; repeated bites may lead to an allergic reaction, which may lead to pronounced cutaneous manifestations. Some patients show a severe systemic hypersensitivity to arthropod allergens. The site of the bite can also become secondarily infected with bacteria infection and lead to ecthyma, cellulitis, and/or lymphangitis.
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
