Bed bug feces are often one of the earliest and most reliable signs of a bed bug infestation. The dark brown or black ink-like dots are often tricky to spot but can be found with careful inspection. Early detection is especially helpful in Texas, where warm weather can allow bed bugs to reproduce quickly.
For more insight into what bed bug feces look like and where they’re commonly found, we spoke with Alan Brown, Board-Certified Entomologist and Technical Director at ABC Home & Commercial Services.
“Bed bug feces are digested blood. The fecal spots are black liquid and look very much like ink spots.”
He explains that these spots are typically found close to where bed bugs live and feed, including:
“Bedding, night stands, head boards, couches, chairs, etc.”
Take a closer look at how to identify these feces and what steps to take if you spot these or other signs of bed bugs.
What Bed Bug Feces Looks Like
Knowing what bed bug feces look like is the first step to identifying them in your home.
Appearance and Characteristics
Bed bug feces are made up of digested blood, so they have a dark brown to black color. They show up as pinpoint to ink-dot-sized specks, making them difficult to spot. They also have a distinct texture that smears like black ink when rubbed. Here’s a quick breakdown of what bed bug feces looks like in comparison to other things you may see around your home.
Common Places You’ll Find Bed Bug Feces
You’re most likely to spot bed bug droppings around mattress seams and piping, headboards and boxsprings. Couches and recliners are also common areas where bed bugs can live.
You might find droppings along baseboards, too. Inspect electrical outlets for any signs of droppings as well.
Why Bed Bugs Leave Feces and What It Means for Your Infestation Level
Bed bugs feed on blood, and that leads to distinct droppings. Understanding bed bug feeding and waste habits can help you understand the severity of an infestation.
How Bed Bug Digestion Produces These Stains
When bed bugs feed on blood, they excrete it almost immediately. This leaves behind the distinct color and texture of the droppings. Each bed bug can leave multiple fecal spots per day due to their fast digestion.
What the Amount of Feces Tells You
The amount and distribution of feces can indicate the severity of the infestation. Light spotting in isolated areas often points to early-stage infestation. If you’re finding heavy clusters, there is likely an established colony.
You may find shed skins or even live bugs alongside groups of feces. If you do, it’s time to call in a local pest control pro.
Is Bed Bug Feces Harmful?
Bed bug feces do pose a risk in certain situations, but aren’t as harmful as many might think. However, it’s still important to properly clean any areas where you find them.
Potential Reactions
While most people don’t react to bed bug feces, there is a risk for people with asthma or allergies. Skin irritation from touching the feces is one of the most common symptoms.
The feces also pose a risk of secondary skin infections from scratching bites where feces are present. This is especially relevant for children, the elderly and others with weaker immune systems.
What Bed Bug Feces Cannot Do
Unlike droppings from other types of pests, bed bug feces do not transmit disease. However, it’s still necessary to clean up any spots properly.
How to Remove Bed Bug Feces (Step-by-Step Guide)
You will want to approach removing these feces properly. Here’s how to clean bed bug feces the right way.
Materials Needed
You can clean up bed bug feces using the following supplies and tools:
-
Wear disposable gloves to protect your skin
-
Use an enzyme-based cleaner to help break down organic residue
-
Scrub with a stiff brush, hot water and detergent
-
Wipe up residue with disposable paper towels
Use a HEPA vacuum to remove feces from cracks, seams and other hard-to-reach areas
Cleaning Methods by Surface Type
For mattresses, apply enzyme cleaner and use a blotting motion to avoid smearing. Wash any sheets or clothing on a high-heat cycle of 120 degrees or higher for thorough cleaning.
Walls and baseboards are easily handled with a damp wipe. If staining persists, you may have to repaint. Spot cleaning is often suitable for furniture, but upholstery can require steam treatment for a thorough clean.
Important Disclaimer
While cleaning removes stains, it doesn’t tackle the bed bug infestation itself. You will need professional treatment to deal with the bed bugs.
How Professionals Confirm Bed Bugs (Inspection Techniques)
If you spot signs of bed bugs, you’ll need to reach out to a local pest control professional for a bed bug inspection.
Brown explains that ABC begins with a careful, methodical approach.
“We start with a thorough visual inspection of all living and bedding areas (mattresses, box springs, couches, chairs, etc.).”
If no immediate signs are found, Alan notes that monitoring may be the next step.
“If no signs are found, we often place glueboards and return in one to two weeks for a follow-up inspection. The glue boards help us determine if there are other arthropods that may be causing a problem, and a reinspection of the living and bedding furniture will show us if any signs have developed.”
This multi-step inspection process helps confirm whether bed bugs are present and avoids unnecessary treatment.
Why DIY Identification Is Often Wrong
Going on intuition alone is often difficult because bed bug feces can look like dirt, mold or roach droppings. Professionals know what patterns to look for and what feces distribution means. Instead of going it alone and trying off-the-shelf solutions like bed bug bombs, it’s better to go with trained pest control professionals.
How to Prevent Bed Bug Feces: Eliminating the Source
You can take a few simple steps to help reduce the chances of bed bug feces becoming an issue in your home. Certain prevention tips are particularly useful in Texas.
Brown recommends being cautious with items that could introduce bed bugs into your home.
“Be very careful if you buy used items at garage sales, thrift stores or from online sources.”
Travel is another common risk factor.
“Launder all your clothing soon after returning home from travel and store your suitcases in the attic or garage instead of bedrooms or closets.”
Home Prevention Tips
-
Reduce clutter and seal cracks in walls and bed frames
-
Use mattress encasements to limit hiding spots
-
Heat-dry bedding weekly
-
Be cautious with secondhand furniture and décor
Inspect luggage and wash clothes after travel
Stopping bed bugs from taking hold in the first place is the best way to keep them out of your home.
Texas-Specific Bed Bug Risks
Warm-weather areas provide ample opportunity for bed bugs to move from person to person. While bed bugs can live in colder climates, they are much less active.
College towns can pose higher risks due to the high turnover and constant moving of bedding and clothes.

Understanding when to contact a pest control professional in Texas can help stop further spread of a bed bug infestation.
Signs You Need Immediate Treatment
Getting immediate treatment if you spot signs of bed bugs is the best course of action. If you notice feces in multiple rooms, then it’s time to reach out. This is also the case if there are clusters of stains near sleeping areas. Any confirmed bites or verified bed bug feces are reasons to act as soon as possible.
What a Texas Pest Control Company Will Do
Your local pest control professionals can inspect your home to verify whether bed bugs are present and evaluate the infestation level. Heat treatment is a highly effective option and is popular in Texas thanks to its rapid results. This is because heating your home to very high temperatures for a few hours sterilizes bed bug eggs to stop reproduction.
For persistent issues, chemical barriers can deter bed bugs from entering. Follow-up monitoring allows for rapid action if the infestation continues.

Tackle Bed Bug Feces at the Source
Finding bed bug feces is one of the earliest and most reliable indicators of an active infestation. While the black, ink-like stains made of digested blood aren’t a concern in themselves, they point to ongoing feeding and reproduction. Cleaning is a necessary step, but it doesn’t tackle the bed bugs in your home.
Keeping an eye out for infestations early helps prevent them from spreading to multiple rooms. The warm weather and travel patterns in Texas mean that homes are often especially vulnerable. A professional inspection is the best way to confirm an infestation and deal with the problem.
