Many news reports in recent years have focused on the discovery of bedbugs and their health effects (even in upscale five-star hotels), and a number of lawsuits have been filed by guests of fashionable hotels who awoke to find hundreds of bedbug bites covering their skin. Searching on travel-review web sites regularly reveals information and even photos confirming the presence of bedbugs in numerous hotels.
The mechanism of skin injury by arthropods depends on the structure of the mouthparts. These insects are categorized as vessel feeders if they insert the tip into a capillary or as pool feeders if they feed on the extravasated blood from damaged tissue. They often inject different pharmacologically active substances (eg, hyaluronidase, proteases, kinins), which may cause different skin reactions (eg, erythema, wheal, vesicle, hemorrhagic nodule).

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!!!
It’s perfectly natural to want to eliminate a bed bug infestation without spending a ton of money on professional-grade products or a treatment by a pest control operator. When people discover that they have bed bugs, they often turn to do-it-yourself recommendations from discussions on the Internet. These suggestions might include household items, some of which are recommended more often than others. Let’s take a closer look at some of the most popular items and how they might be used against bed bugs:
Stripping and vacuuming the mattresses and box springs, and encasing them.  Double bag your bedding and wash in hot water and dry for at least 30 minutes (discard the inner bag after putting bedding into the washer, as it could have bed bugs).  After vacuuming suspected bed bugs from the bed, take your vacuum cleaner outdoors and remove and discard the bag.  Purchase a good quality set of bed-bug-proof encasements for your mattresses and box springs. Bed bug-proof encasements are fabric sacks into which you slide your mattress or your box spring. The zippers on bed bug encasements are designed to be tight enough to prevent even the smallest life stages of the bed bugs from escaping. Also, good bed bug-proof encasements are woven to prevent bed bugs from biting you through the encasement. A good encasement will trap all bed bugs in the mattress and box spring inside, and will be smooth on the outside, providing few places for bed bugs to hide. Sears, Target, Walmart and other stores may sell bed bug-proof encasements, but these can also be purchased online. A good place to look for different brands and reviews of mattress encasements is (whether you buy there or at a local store). Go to and search for “bed bug mattress protectors”.
