Bed Bug Feces (droppings): Bed Bug Feces is usually found around creases along the mattress and or box spring. Droppings can also found along the back of the head board or artwork hanging above the head of the bed. Bed bug droppings are always black and look like the marks of a felt tip pen and tend to bleed into the fabric, carpet, etc…They do not rub off.

Blood Smears: Smears of blood on sheets/pillows are also one of the early warning signs that there may be an infestation. Bed bugs do not fully close their mouths around the bite site when feeding, leaving drops of blood and residual marks. Also, bed bugs have an anti-coagulant whoch keeps the blood flowing. However, there are many other reasons that blood smears could be visible, and blood alone is not evidence of a Bed Bug infestation.

Casings: As the bed bug molts into its next life stage, the old skin casings are left behind. Cast skins (casings) look like lighter colored empty bed bug shells – which is basically what they are. They can vary in size and in color. They get lighter in color over time.

Live Bed Bugs: Live Bed Bugs are, of course, the most obvious sign of a Bed Bug infestation. Live Bed Bugs can be found in any part of the unit, including the bathroom, because they are hitch-hikers. They can easily be introduced to any room that a guest has had clothing, linens, luggage, etc…Bed bug refuges contain bed bugs of all sizes.

Eggs and Eggshells: Bed Bug Eggs and Empty Egg Shells are certainly symptoms of a growing multi-generational bed bug population. They are very small – about 1 mm in length – but visible to the naked eye – a magnifying glass helps. They are usually white in color, but can be opaque. Also, they are rarely found alone, but usually as part of the refuge site (in between mattress seams, etc..) with other signs of an infestation such as casings, feces and live bugs.
