How to Identify Bed Bug Droppings

One of the best ways to identify a pest infestation is by looking for droppings. Bed bugs are no exception, and finding feces on a mattress is a good indication that they've invaded the home. If you've spotted mysterious dark spots on your mattress and your stomach dropped a little, take a breath. This guide will walk you through exactly what bed bug droppings look like, where to find them, and what to do next.

Key Takeaways

• Bed bug droppings signal an active infestation. These spots are made of digested blood, so finding them means bed bugs have been feeding nearby.

• They look like tiny dark dots. Think rust-colored, brown, or black spots roughly the size of a marker tip, often clustered together.

• Check the usual hiding spots. Mattress seams, box springs, headboards, and baseboards are prime real estate for bed bugs and their droppings.

• Look for backup evidence. Shed skins, tiny eggs, and small blood smears help confirm you're dealing with bed bugs and not another pest.

• When in doubt, call a pro. Orkin's trained technicians can confirm an infestation and stop it before it spreads.

What Do Bed Bug Droppings Look Like?

Bed bug droppings are basically the aftermath of a meal. After a bed bug feeds on blood, it leaves behind small deposits of partially digested blood—which is why the spots tend to be so dark.

Here's what to look for:

• Color: Rust-colored, dark brown, or black

• Size: About as big as the dot from a felt-tip marker

• Pattern: Usually appear in clusters rather than as a single spot

• Texture: May smear if you wipe them with a damp cloth, since they're made of dried blood

• Smell: A large infestation can leave a musty, sweet odor in the room

The spots often soak into fabric a bit, so you may notice they look slightly blurred at the edges rather than perfectly round.

Where to Look for Bed Bug Droppings

Bed bugs like to stay close to their food source, that's you. So they tend to leave droppings near where you sleep and rest. For the best results, grab a flashlight and inspect these areas first thing in the morning.

Fecal spotting is usually found in the following places:

• The seams of a mattress

• Box spring frames

• On or behind the headboard

• Along baseboards near the edge of the carpet

At times, bed bug droppings can look similar to those of other pests, including cockroaches. One of the easiest ways to tell the difference is to look for additional evidence such as shed skins, hatched eggs, or the presence of blood.

How to Tell Bed Bug Droppings Apart From Other Pests

Bed bugs aren't the only pests that leave droppings behind, and a few can look similar at first glance. Here's how to tell the difference:

• Cockroach droppings are usually larger and more cylindrical, almost like tiny grains of rice or coffee grounds.

• Flea droppings look like small, dark specks—often compared to pepper or dirt—and turn reddish-brown when they get wet, since they also contain digested blood.

The easiest way to confirm bed bugs? Look for extra clues. Shed skins, empty eggshells, or small blood smears on your sheets all point to a bed bug problem rather than a different pest.

Problems Associated with Bed Bug Droppings

Bed bugs are not currently known to spread disease, but their bites can lead to irritated skin and concerned homeowners. Additionally, infestations can quickly grow out of control if not handled immediately. Once feces or other signs of bed bugs have been detected, contact the trained professionals at Orkin.

What to Do If You Find Bed Bug Droppings

Spotting droppings is a strong sign—but not absolute proof—that bed bugs are present. The only way to know for sure is to find a live bed bug, and that can be tricky since these pests are experts at hiding.

Here's how to respond:

• Inspect thoroughly. Check your bedding, mattress, and nearby furniture for live bugs, shed skins, eggs, or additional droppings.

• Don't try to sleep it off elsewhere. Moving to another room can actually spread bed bugs to new areas of your home.

• Avoid DIY overkill. Store-bought sprays often scatter bed bugs rather than eliminate them, making the problem harder to treat.

• Call in the experts. A trained technician can confirm the infestation and create a plan to get rid of it for good.

When to Call a Professional for Bed Bug Treatment

If you've found droppings and any other signs of bed bugs, it's time to bring in reinforcements. Bed bugs are notoriously difficult to eliminate on your own, and a small problem can quickly get out of hand.

The trained professionals at Orkin know exactly where these pests hide and how to stop them. Contact Orkin for a thorough inspection and a treatment plan designed to protect your home—and your sleep—from unwelcome guests.
