Identifying Bed Bug Bites Through Pictures and Descriptions
Trying to figure out if you have bed bugs? Pictures of bites can help identify an infestation. Learn exactly what bed bug bites look like compared to other insects, the signs and symptoms, and how to stop the itching and prevent further bites.
Do I Have Bed Bugs? How Infestations Happen
Before exploring what bed bug bites look like, it helps to understand what causes them in the first place. Bed bugs are small, flat, parasitic insects that feed on human and animal blood. They come out at night, typically biting exposed skin to extract blood for food.
Bed bugs infest homes, usually hiding in mattresses and bedding. Their small size enables them to hide in cracks and crevices too. People most often bring them in by:
- Used furniture or second hand beds
- Luggage after traveling
- Visitors clothing and purses
- Sharing infested laundry facilities
A bed bug can survive months without feeding. Females lay hundreds of small white eggs during their lifespan. So while just one or two brought in can spark an full blown infestation through rapid breeding.
What Do Bed Bug Bites Look Like Exactly?
Wondering what kind of bug bites look like bed bugs? When they extract blood, the saliva they inject creates small, swollen itchy red bumps often described as:
- Size of a pencil eraser tip or mosquito bite
- Raised itchy red welts in zigzag lines or clusters
- Fluid-filled blisters before scabbing over
- Hive-like skin reactions in sensitive people

As you see, bed bug bites resemble mosquito and spider bites. So be sure also to watch for these other signs of an infestation:
- Blood stains on your sheets from crushed insects
- Seeing live bed bugs crawling at night
- Distinctive musty stink bug smell around beds
- Molted bed bug skin shells around tufts and seams
How Are Bed Bug Bites Different From Other Insects?
What bugs look like bed bugs? While similar to other bites, some unique distinctions stand out. Compare appearances below:
Bed Bug Bites vs Mosquito Bites
- Bed bugs leave cluster or zigzag line patterns, mosquitoes usually bite singly
- Mosquito bites are round, bed bug have more raised wheal shape
- Bed bug welts can appear days later, mosquitoes bite right away
Bed Bug Bites vs Spider Bites
- Bed bugs leave multiple bites in a line or grouping
- Spider bites may have central puncture spot from fangs
- Spider bites swell rapidly, bed bug welts emerge slowly
Bed Bug Bites vs Scabies
- Scabies burrow trails under skin, bed bugs dont tunnel just bite
- Scabies transmitted human-to-human, bed bugs from places not people
- Whole body can be affected by scabies, bed bugs concentrated around sleeping areas
Bed Bug Bites vs Flea Bites
- Flea bites usually around ankles, bed bugs anywhere skin exposed during sleep
- Flea bite patterns very random, bed bug bites orderly cluster or lines
- Fleas jump from pets and carpets, bed bugs associated with beds
Do Bed Bug Bites Always Appear or Itch?
No, thats part of the tricky thing about identifying them! Everyone's skin reacts differently. Bite appearances and sensations can vary:
- No signs at all - approximate 20-30% of people show no skin reaction
- Delayed itching or lesions - bites can take as long as 14 days to emerge
- No itch but bites visible - uncommon but without typical itching sensation
- Intense itching and swelling - allergic-like responses in sensitive individuals
So lack bites or itching alone doesnt rule out an infestation. Consider other signs like blood stains or seeing the insects themselves.
How to Treat Bed Bug Bites
The good news about bed bugs vs other pests? They dont spread contagious diseases. But those itchy welts still demand some TLC. Follow these self-care tips:
- Apply anti-itch creams with soothing ingredients like menthol, calamine, pramoxine
- Try OTC hydrocortisone cream to ease inflammation and swelling
- Take oral antihistamines like Benadryl to reduce skin reactions
- Dab apple cider vinegar for mild numbness and itch relief
- Run a cool compress over bites to alleviate itching
- Avoid harsh scrubbing to prevent infection risk
Severe skin responses may warrant oral steroids or antibiotics if infection develops. But try home treatment first for a few days. Preventing new bites is most vital!
How to Get Rid of Bed Bugs
Eliminating bed bugs requires diligence to inspect, treat and monitor:
Inspect and Remove Infested Items
- Check mattresses, box springs, bed frames thoroughly
- Scan creases, tufts, tags and seams for bugs and staining
- Vacuum all cracks and crevices in sleeping areas
- Seal inspected items in plastic bags to trap bugs inside
- Discard heavily infested mattresses and furniture
Apply Registered Chemical Treatments
- Hire a professional pest control company for whole home heat or spray treatments
- Treat mattresses with EPA-approved products made to kill bed bugs and eggs
- Repeat applications to kill newly hatched nymphs after eggs hatch
Without proper removal and coordinated treatment inside cracks, bed bugs often rebound post treatment. Be sure to:
- Isolate treated mattresses/furniture for 1-2 weeks
- Wash and heat dry (140F+) all fabrics after room treatment
- Carefully encase mattress and box spring in covers
- Trap and monitor for recurrence; retreat if needed
The Takeaway: Identify Bites Early On
Noticing bed bug bites right away aids prompt treatment before infestations get out of hand. While they resemble other insect bites, their grouping patterns in zigzags or lines points more distinctly to bed bugs vs mosquitos, spiders, etc.
Confirm with other signs like seeing actual bed bugs, blood smears and skin casts. Addressing infestations takes diligence but gets easier the earlier detected.

FAQs
Do bed bug bites leave permanent marks?
In most cases, bed bug bites heal fully without permanent marks or scarring. Proper wound care limits lasting visible damage. However, those prone to skin discolorations may develop temporary or permanent marks from severe swelling, inflammation, or scratching.
Can you get just one bed bug bite?
While possible to get a single bed bug bite, they more typically feed in groups of two or three. Females also emit aggregation pheromones that attract other bed bugs to the feeding location. So clusters or trails of multiple bites are more common.
Do bed bugs fly and bite you?
No, bed bugs cannot fly. They crawl very quickly over floors, walls and ceilings to reach hosts. The bugs then bite exposed skin, often around sleeping areas. Some people wrongly attribute bites to sand flies or biting midges which can fly and feed on humans.
Can bed bugs live in your hair or scalp?
No, bed bugs do not reside in human hair or directly on our scalp for very long. They feed on blood by piercing skin, not burrowing. Sometimes newly hatched nymphs briefly crawl through hair seeking exposed skin. But they don't take up residence or reproduce there.
