What do bed bug blood stains look like?

Published in Pest Identification 3 mins read

Bed bug blood stains typically appear as small, red or rust-colored spots or smears on your bedding, clothing, or surrounding furniture.

Detailed Description of Bed Bug Blood Stains

When bed bugs feed, they often leave behind traces of blood. Recognizing these stains can be a crucial sign of a bed bug infestation. Here's a more detailed look:

  • Color: Fresh stains are usually bright red. As the blood dries, it oxidizes and turns a rusty or dark brown color.
  • Size and Shape: Stains are typically small, ranging from pinhead-sized spots to larger smears. They may appear as:
    • Small dots: These are often seen where a bed bug was crushed after feeding.
    • Smears: These occur when a bed bug is disturbed during feeding and moves, leaving a trail of blood.
    • Clusters: Multiple spots may be clustered together in areas where bed bugs frequently feed.
  • Location: The most common places to find these stains include:
    • Bed sheets: Particularly fitted sheets and flat sheets.
    • Pillowcases: Especially along the seams.
    • Mattresses: Inspect along seams, tufts, and under labels.
    • Box springs: Check the fabric covering.
    • Bed frames: Look for stains on the headboard, footboard, and side rails.
    • Nearby furniture: Bed bugs can hide in nightstands, dressers, and other furniture near the bed.
    • Clothing: Especially clothing left on or near the bed.

How to Differentiate Bed Bug Blood Stains from Other Stains

It can be challenging to distinguish bed bug blood stains from other types of stains. Here are a few tips:

  • Consider the context: Are you also experiencing other signs of bed bugs, such as bites, shed skins, or live bed bugs?
  • Check for patterns: Bed bug stains tend to be clustered or smeared, rather than randomly distributed.
  • Test the stain (carefully): Lightly dab the stain with a damp cloth. Blood stains will often smear or bleed.
  • Compare with other possible stains: Consider whether the stain could be from another source, such as a cut, a nosebleed, or spilled food.

What to Do if You Find Suspected Bed Bug Blood Stains

If you suspect that you've found bed bug blood stains:

  1. Inspect thoroughly: Conduct a detailed inspection of your bed, bedding, and surrounding furniture for other signs of bed bugs.
  2. Contact a professional: If you find evidence of bed bugs, contact a qualified pest control professional for an inspection and treatment.
  3. Wash bedding: Wash all bedding in hot water and dry on high heat to kill any bed bugs or eggs that may be present.
  4. Vacuum: Vacuum the mattress, box spring, and surrounding areas thoroughly.

By being vigilant and recognizing the signs of bed bug activity, you can take steps to address an infestation early and prevent it from becoming more severe.
