How to know you have BED BUGS

Updated on March 6, 2026 by Jeremy Mwangelwa

Sign 1: Waking Up with Unexplained Bites

One of the first and most common signs that you may have bed bugs is waking up with itchy bites on your skin. Bed bugs are nocturnal and feed on human blood while you sleep. Their bites often appear in clusters or rows and tend to be itchy and slightly swollen.

Here are some characteristics of bed bug bites:

  • Small, itchy bumps: These bites are typically small and red, often appearing in lines or groups. If your skin complexion is darker, they might appear purple.
  • Location on the body: Bed bug bites usually occur on exposed skin, such as the arms, legs, neck, face, and hands.
  • Itching: Bed bug bites can cause significant itching, and some people may develop a rash or allergic reaction.

It’s important to remember that not everyone reacts to bed bug bites in the same way. Some people may not have visible bites or feel itchy, even if bed bugs are present. However, if you consistently wake up with unexplained bites, it's quite likely that you have bed bugs.

Sign 2: Finding Rusty or Dark Stains on Bedding

Bed bugs leave behind distinct stains as they feed or move around. These stains can be found on your mattress, bedding, pillowcases, or nearby furniture.

Types of stains to look for:

  • Fecal spots: Bed bugs leave behind dark, rusty-brown or black spots of excrement, that is poop. These are usually found in clusters along mattress seams, pillowcases, and bed frames.
  • Blood stains: You may find small reddish-brown bloodstains on your sheets or pillows. These stains happen when you roll over and crush a bed bug after it has fed.

Inspect your bed linens and mattress regularly for these stains. They are one of the most reliable signs that bed bugs are present in your home.

Sign 3: Shed Bed Bug Skins

As bed bugs mature, they shed their exoskeletons, leaving behind empty shells. These shed skins are a clear indication of bed bug activity, as they typically remain near the bugs’ hiding spots.

Here' what shed bed bug skins look like:

  • Translucent or yellowish-brown: Bed bug skins are small, translucent, and typically yellowish-brown in color. They can vary in size depending on the stage of development of the bug.
  • Location: Look for shed skins around mattress seams, bed frames, baseboards, and in the crevices of furniture.

If you find bed bug skins, it means they are actively growing and reproducing in your home, and the infestation is likely spreading.

Sign 4: Detecting a Musty, Sweet Odor

In large infestations, bed bugs release a musty, sweet odor caused by pheromones they use to communicate with each other. This smell is often described as similar to overripe fruit or moldy shoes.

Here's where you might notice the odor:

  • Near your bed: Since bed bugs typically hide close to their feeding source, you’re most likely to detect this odor in the bedroom, especially near the bed.
  • Furniture and carpeting: If the infestation has spread, the odor could also be present in couches, chairs, and other upholstered furniture.

While the smell is not always noticeable in smaller infestations, if you detect a sweet, musty odor that wasn’t present before, it could be a sign of bed bugs.

Sign 5: Spotting Live Bed Bugs

Bed bugs are small but visible to the naked eye. Adult bed bugs are about the size of an apple seed, with flat, oval-shaped, reddish-brown bodies. After feeding, they become swollen and darker in color. Nymphs, or young bed bugs, are smaller and lighter in color but can still be seen.

Here's where to look for live bed bugs:

  • Mattress seams and folds: Bed bugs tend to hide along the seams and edges of mattresses and box springs.
  • Bed frames and headboards: Check the cracks, joints, and crevices of your bed frame and headboard, as these are common hiding spots.
  • Nearby furniture: Bed bugs can also hide in nightstands, dressers, and other furniture close to your bed.

If you spot even a single bed bug, it's time to start getting rid of them immediately.

Sign 6: Seeing Bed Bugs During the Day

While bed bugs are nocturnal and primarily feed at night, severe infestations may cause them to be visible during the day. If you start seeing bed bugs moving around during daylight hours, it’s a sign that the infestation has grown and that they are struggling to find hiding spots. Bed bugs try to match your sleep patters and are most active when you are least active so that they are not disturbed as they bite you.

Here's where you might see bed bugs during the day:

  • Mattresses and bedding: Bed bugs may be spotted on your bed, especially near seams and folds.
  • Furniture and walls: In large infestations, bed bugs may venture beyond the bed and into nearby furniture or even along baseboards and walls.

If you see bed bugs during the day, the infestation is likely well-established, and you need to take action immediately.
