You can pick up bed bugs almost anywhere — offices, stores, hotels and gyms for starters. They’re great at hiding and have been known to hitchhike in luggage, personal belongings or even you. Once indoors, they can be very difficult to control without the help of an experienced pest specialist.
Depending on the life cycle stage, bed bugs can range from translucent yellowish (newly hatched) to rusty brown (adult stages) and even bright red after a blood meal. Unfed, bed bugs are flat and oval, yellow to golden brown with a dark squiggle on their abdomen (that's their digestive system). After a blood meal, they're plump and reddish brown.
As their name implies, bed bugs like to live and feed in beds, where you spend a long amount of time at rest, so they can take advantage of you, their food source. They also live behind baseboards, wallpaper, picture frames, drapery folds, upholstery, in pet beds, and in furniture crevices.
Blood; primarily human, but bed bugs will dine on any warm-blooded animal.
