Can Bed Bugs Bite Through Clothes?

Why Do Bed Bugs Bite Humans?

Bed bugs are a common pest that you might encounter, especially in places where humans rest or sleep. These insects thrive on a blood meal to survive, which is why they seek out humans.

They are nocturnal creatures. This means they mainly feed at night while you are asleep.

When bed bugs bite, their goal is to draw blood for sustenance.

These insects use two mouthparts. One injects an anesthetic and an anticoagulant. This prevents you from feeling the bite immediately. The other sucks the blood.

This stealthy approach allows them to feed without detection.

The proximity of bed bugs to human environments is key to their feeding habits. Bed bugs live in mattresses, bed frames, and other areas close to where people sleep.

Their flattened bodies make it possible for them to fit into tiny spaces and remain undetected.

Here is how a typical infestation and feeding pattern might look:

  • Environmental Preference: Prefer warmth and carbon dioxide-rich environments, often found in bedrooms.

  • Feeding CycleBed bugs may feed every 5-10 days, but they can survive months without a blood meal.

  • Feeding Duration: They typically feed on your skin to feed for about 3-10 minutes until engorged.

These pests do not transmit diseases through their bites. But, their presence can cause itching and discomfort.

Recognizing the signs of an infestation is essential for timely intervention. Bite marks in a line or cluster on exposed skin are an example of such signs.

What Does A Bed Bug Bite Look Like?

When you wake up with itchy spots you didn’t have before sleeping, bed bug bites may be the culprit.

Typically, these itchy bites are small, raised, red welts and often have a darker red spot in the middle.

Bites usually occur on exposed skin, which was not covered by clothing while you were asleep. They are often arranged in lines or clusters.

Bed bug bites can appear differently on different individuals. Some might experience a stronger reaction than others. For instance:

  • Itchy bites: Almost universally, bites from bed bugs are itchy and uncomfortable. Resist the urge to scratch – it can lead to infection.

  • Bites usually occur on exposed skin: Common areas include the face, neck, arms, and hands.

  • Bites also: can cause symptoms like redness, swelling, or even blisters in more severe reactions.

The timeline for these bites can vary:

  • Bites can take a few days to appear after the initial biting incident.

  • Bites may: persist for several days or even weeks and gradually fade away.

One common myth is that bugs can bite through clothes — generally, they cannot. Bed bug bites usually happen on skin that was exposed during sleep.

Unlike other insect bites, bed bug bites commonly form a line or cluster. If you see bites in a zigzag or line pattern, bed bugs might be the cause.

Can Bed Bugs Bite Through Clothes?

The straightforward answer is, bed bugs cannot bite through clothing. They simply do not possess mouth parts strong enough to break through fabric.

However, if your clothing is loose enough, bed bugs can navigate to your skin. They are adept at finding ways to access skin, usually opting for exposed surfaces.

But they might crawl under loosened clothing to feed.

To best protect yourself, wear long sleeves and pants. This can reduce the risk of bites on covered skin areas.

However, clothing with holes or that fits tightly could still allow these pests to find their way to bite you.

Here are key points to remember about bed bug bites and clothing:

  • Protection Offered by Clothes: Clothes may provide some defense, but they are not a foolproof barrier.

  • Bed Bug Behavior: They lean towards exposed skin rather than trying to bite through clothing.

  • Garment Structure and Fit: Tightly-fitted clothes or those with holes diminish the protective barrier against bed bugs.

Can You See Bed Bugs Crawling On Your Skin?

Yes, you can see bed bugs crawling on your skin. Bed bugs are nocturnal insects, which means they are most active at night.

However, if they are hungry and without hesitation, they might come out during the day to feed. Recognizing these pests with your naked eye is not impossible due to their size.

Adult bed bugs are about the size of an apple seed and are visible to the human eye.

They have reddish-brown, oval-shaped bodies. You can spot them when they crawl over the skin. Here’s a brief description:

  • Color: Reddish-brown

  • Shape: Oval

  • Size: Typically 5-7 mm long

Bed bugs have six legs, which allow them to move quickly across surfaces, including your skin.

When you’re trying to see them on your skin, your best chance is probably while you’re awake and alert.

Because of their size and the fact that they do not like light, spotting bed bugs can be a challenge.

They are skilled at hiding in the seams of mattresses. They also hide between cushions and in other nearby crevices.

Bed Bug Bites Versus Mosquito Bites – How To Tell The Difference?

When you notice itchy bites on your skin, it’s vital to identify whether they’re from bed bugs or mosquitoes. This will guide your approach to treatment and prevention. Here’s how to tell them apart:

Location: Typically, bed bug bites occur in a line or cluster, focused on areas of your skin that are exposed while you sleep. Mosquito bites are more randomly placed and can be anywhere on your body.

Bite Appearance: Bed bug bites often become red and swelling may occur. They sometimes have a darker red spot in the middle. In contrast, mosquito bites are usually puffy and redder. They have a single puncture point where the mosquito inserted its proboscis.

Reaction Time: After being bitten by a bed bug, it might take a few days to develop any symptoms. Conversely, mosquito bites usually cause immediate itchy sensations, though individual reactions can vary.

Symptoms and Duration: The itchiness from bed bug bites can persist for several days and may even lead to severe reactions in some individuals. Mosquito bites, on the other hand, tend to start fading and becoming less itchy within a few days.

Aspect Bed Bug Bites Mosquito Bites
Location Linear or clustered, exposed skin Random, anywhere on the body
Appearance Red, swollen, darker red spot in the middle Puffy, red with puncture point
Reaction Time Delayed, may take days Immediate, varies per person
Symptoms Duration Longer, persistent itch Shorter, diminishes quickly

Best Pajamas To Wear To Prevent Bed Bugs

When selecting pajamas to protect yourself from bed bugs, consider opting for clothing that covers as much of your skin as possible. 

Choose a full-sleeved top and long pants to minimize skin exposure. It’s crucial that the fabric is tightly woven so bed bugs cannot easily penetrate it. 

Light-colored pajamas may also be advantageous as they make it easier to spot any bed bugs.

Here’s a quick guide to the types of pajamas to look for:

  • Material: Preferably smooth, synthetic fabrics as they provide less grip for bed bugs compared to rough or textured materials.

  • Fit: The pajamas should be loose enough to be comfortable but fitted enough to prevent bed bugs from gaining easy access to your skin.

  • Cuffs: Elastic cuffs at the wrists and ankles can provide additional protection.

  • Closure: Opt for pajamas without gaps; buttons and zippers should close tightly.

Remember to keep pajamas exclusive for bedtime use. Wash them frequently at a high temperature.

Drying on a high heat setting is also effective in killing any bed bugs or eggs that may have come into contact with the fabric.

  • Wash and dry bedding and pajamas at high heat

  • Avoid using second-hand or worn-out pajamas with holes


 Bed bugs can’t bite through clothes, but they can crawl on skin that’s not protected with fabric.

To keep yourself safe, wear full-sleeved clothing. Also, wear long pants to cover up as much exposed skin as possible.

Make sure to select pajamas that are made of tightly woven fabrics with no gaps or holes.

Wash and dry bedding and pajamas at high heat settings regularly. The above tips will go a long way in protecting you from these pests while sleeping.
