It’s cost us about 3 to 6 hundred dollars to get them exterminated. Alcohol does kill on contact but it takes a lot more than that. Some things need to be bagged up until you can wash all clothes! They can live without feeding on your blood for months and months! I had them feeding on me but my husband worked outside and had darker skin so they weren’t biting him at first until they found his white legs! He was sporting a farmers tan.LOL
While the mattress and box spring are left to dry, spray down the joints of the bed frame, headboard, and footboard with a contact spray and residual spray. The contact spray will kill bed bugs quickly and then evaporate, while the residual spray will kill bed bugs over several weeks. Remember to follow the sprays’ product labels and MSDS for safe and effective usage.
Wash bedding and clothing (hot water and hot drying cycle for 30–60 minutes), vacuum cracks and crevices, and freeze articles that may have been used as hiding places for bedbugs may reduce infestation until extermination can be performed. Vacuum with special attention to cracks and crevices in furniture, equipment, walls, and floors. Vacuuming some talcum powder will reduce the chance that the bugs will crawl out of the vacuum cleaner. Dispose of the vacuum cleaner filter and bags in a tightly sealed plastic bag. 
Some bed bug species are parasites of bats or birds, and may bite people if the wild hosts are no longer available. Although similar in overall appearance, the species of bed bugs that normally feed on bats, swallows, chimney swifts, pigeons or other wild hosts can be differentiated from those that prefer humans. Entomologists and knowledgeable pest managers can make this determination. If bat bugs or bird bugs are present, roosting and nesting sites should be the primary focus, and the animals should be removed and excluded from the building.
