What Does Bed Bug Poop Look Like

If you wake up in the morning with redness on your skin, mosquito bites would be a relieving thought. Bed bugs, on the other hand, are a serious concern. Calling for an expert diagnosis would tempt many of us.

Luckily, bed bugs leave several traces, including human blood and droppings. Bed bug excrement is easier to spot than the bed bug itself because of its darker colour.

So, what does bed bug poop look like?
In this article, we’ll discuss the signs of bed bug droppings so that you can identify them before issuing a false alarm.

Characteristics of Bed Bug Dropping

Bed bug poop can be mistaken for ink or blood spots. Here are some characteristics that can help you spot it:

  • Luckily, bed bug poop on the mattress won’t give a foul smell. You might even need help locating the droppings with your nose. Bed bugs have a more recognizable odour than their droppings. Still, you might be able to notice the rusty smell of their droppings, which comes from the blood component.
  • Bed bugs produce black or dark brown droppings but not pure red. That is because the poop contains digested blood so that it won’t hold the original red colour. Red spots, however, can still be signs of a bed bug infestation. They’re likely traces of your blood that the bed bug left behind.
  • Bed bug faecal stains are almost one millimetre, about the size of a ballpoint. Although they’re smaller than the bug, they’re easier to see because of their colour and grouping pattern. You can rarely find isolated stains. Instead, it’s more likely that you’ll find clusters of droppings near the daytime camp of the bed bugs.
  • If left on a non-absorbent surface, like a mattress protector, bed bug droppings should retain their circular shape. Otherwise, they’ll likely soak in wood panels or bed sheets. As a general rule, bed bug poop is water-soluble. So, you can expect them to smear on wet surfaces. If it’s still moist, it’ll have a muddy consistency.

Where to Look for Bed Bug Droppings

Now that you know what you’re looking for, it’s time to start your search. If you suspect a bed bug infestation, you need to inspect all susceptible areas around the house.

Here’s a list of those areas you need to check:

  • Your mattress is where you need to look first. You’re more likely to find bed bugs around the corners of the mattress and tight seams. You can expect to find other clues such as shed skin or bed bugs.
  • Since they’re closely associated with the mattress, bed bugs can likely be inside pillows. Again, check around the seams and any dark folded areas.
  • It’s common to find bed bug stains on wooden bed frames. Look behind the headboard and the dark corners. We recommend you use a torch or your phone’s flashlight to look deep into the holes.
  • It’s unlikely that bed bugs would harbour far from their feast. However, in case of severe bed bug infestations, the bugs can spread to almost any corner. Check carpets, furniture upholstery, and curtains for stains.
  • Although you might save a few hundred dollars on used furniture, infected pieces can spread the bugs around your home. So, be sure to inspect second-hand furniture.
  • Unfortunately, bed bugs won’t limit their territory to your furniture. They might occasionally make it to your home’s walls, especially around cracks.Added to that, you may find bed bug droppings near the ceilings. However, these areas can have cockroach droppings, which look similar to the faeces of bed bugs.One way to know the difference is to put on gloves and press the droppings. Cockroach droppings are granular, while bed bug poop is softer.
  • If you notice dark spots around your electrical outlets or curtain rods, you’ll need to check for bug nests behind them. Try to unscrew any tools attached to the wall to check for more droppings or bed bug nests.
