What do bed bug bites look like?
Some individuals may not react to bed bug bites at all. However, for those who do, the symptoms can be pretty noticeable.
Common signs of a bed bug bite include:
- A red, swollen area with a dark red centre
- Bites that appear in a straight line or cluster
- Blisters or hives at the bite site
Bed bug bites typically appear on areas exposed during sleep, such as the face, arms, legs, and hands.

What are the symptoms of a bed bug bite?
Bed bug bites don’t always appear immediately. Symptoms may take several days to show, making early detection difficult. These pests can also go several days without feeding, meaning bite patterns may seem irregular.
Typical symptoms include:
- Intense itching
- A burning sensation that develops days after being bitten
- Swelling and redness
- Secondary infections from scratching
Bed bugs inject a mild anaesthetic through their saliva, which is why you won’t feel the bite as it happens.

What other bites resemble a bed bug bite?
Unless you’re aware of a bed bug infestation, these bites can easily be mistaken for those caused by other insects. They typically become slightly swollen with an itchy red centre—very similar in appearance to mosquito or flea bites.
Here’s how they compare:
- Bed bug bites: Usually in small groups or straight lines, often red with a darker centre
- Mosquito bites: Randomly spaced, less likely to follow a pattern
- Flea bites: Typically smaller and found around ankles and lower legs
Knowing the difference can help you narrow down the source of the problem and seek the appropriate treatment.
Can bed bug bites cause other problems?
The good news is that bed bugs do not transmit diseases. However, scratching the bites excessively can lead to secondary skin infections. In some cases, people experience insomnia due to stress or fear of being bitten again.
Those who are allergic to bed bug bites may experience:
- Painful swelling and burning at the bite site
- Engorged bite marks
- In rare cases, a severe anaphylactic reaction
If symptoms become severe or unusual, seek medical advice immediately.
How long do bed bug bites take to heal?
Bed bug bites usually take three to six weeks to heal fully. However, if the infestation is ongoing, new bites will appear even as older ones fade. Scratching can lead to delayed healing and a higher risk of infection. Treat the bites with soothing creams, avoid scratching, and consult a pest control expert to address the root cause.
