The most reliable way to identify bedbugs is to hire an expert with a bedbug sniffing dog. Though bedbugs can be difficult to find if there are only a few, they leave some pretty telltale signs that you can possibly identify yourself. A thorough search of the mattress, headboard, and pillows may reveal their presence. Here's how you can inspect for bedbugs. The first sign: Rust-colored stains on the mattress/headboard/pillow. Bedbugs are blood feeders. So, looking for small bloodstains from some sleep-crushed feeding bedbugs is a good place to start. Next, we have cast skins. Bedbugs shed their skin. Being that they love to hang out around beds in search for a tasty snack (you), you can inspect for bedbugs around mattress seams and crevices for old skins. These are brownish, semitransparent, and pretty obvious. Occasionally, you can also find eggs, which are small, cylindrical, and whitish. The key point though, is that you really check the small, hidden spots in the mattress. Common sense and experience dictate that most bugs don't just hang out in the middle of your room; they love cracks, and the smaller the better. Thirdly, poop. Yes, poop. It can be difficult to imagine, but these vampiric nuisances do it just like we do. Obviously, it's much smaller, so you're looking for black dots about twice the size of the period at the end of this sentence. We all know that feeding generally leads to pooping, so this can be a pretty common sign of having bedbugs if you know what you're looking for. Finally, you CAN find the bugs themselves. They are usually nocturnal, but a clean sweep of your mattress can reveal some bugs lodged in the cracks. So check it out. The key is, BEDbugs are usually found in your BED. They will always end up there, because that's where the source of food is. It's not like they can eat something else in the meantime. If there is a large infestation, you should be able to thoroughly comb a bed and discover their presence.
