If you live in an apartment or in a housing unit that shares walls with another unit, you may be more at risk for bed bugs. Because bed bugs will crawl to find more human hosts when their nest grows, high density residences and frequently traveled places like hotels and taxis become bed bug transportation stations. Buying used furniture is another way to acquire bed bugs at home. The best way to reduce your bed bug risk is to carefully check for them when you are changing your bed, returning home with luggage and buying used items. Examine these items outside before bringing them into your home.
