Bed bugs can be spotted by searching the most common areas of infestation, such as mattresses, box springs, couches, drawer joints and electrical receptacles. Even when live bugs are difficult to find, it is possible to spot major signs of infestation, including eggs, excrement droppings and reddish-brown stains from crushed bugs.
Bed bugs have flat, wingless bodies with reddish-brown coloring and measure approximately 1 to 7 millimeters. Bed bugs are often found in sleep environments, such as home bedrooms, dorms, hotels, cruise ships, shelters and trains. They typically stay concealed during the daytime and venture out at night to consume blood.
Bed bugs' tiny bodies can fit in tight spaces, so it's important to check the seams and piping on mattresses, couch cushions and other fabric-based furnishings carefully. Thin crevices near wall and ceiling junctions and inside furniture and appliances may also harbor bed bugs. These critters can hide under peeling wallpaper and between bed linens too. When bed bugs come out for food, they may release excrement that bleeds into fabric and leaves dark spots.Tiny eggs or discarded eggshells, which are usually about 1 millimeter long, may also be visible.
Bite marks appear roughly two weeks after contact and result in red, swollen areas similar to mosquito bites. After being bitten, individuals may also feel itchy or experience allergic reactions.
