Bed bug and mosquito bites are both red and itchy, and they may appear to be the same. They do, however, come from diverse organisms and have a few distinct traits.

Knowing the difference between the two allows people to react correctly to bites they receive and take precautions to avoid obtaining more.

This page compares bed bug and mosquito bites, as well as treatment options.


Bites from bedbugs

Individuals react differently to bed bug bites, just as they do to other bites, and these reactions might take hours or days to manifest.

Bed bug bites itch and irritate some people, while others get swelling, painful reactions.

Anaphylaxis, which begins with a feeling of the throat closing up, is a rare but severe allergic reaction. Anaphylaxis is a life-threatening allergic reaction that affects the entire body.

Individuals are generally bitten by multiple bed bugs at once, commonly in groups of three to five. The bites themselves are red and itchy, with a blister on top of them occasionally.

Bed bugs feed on blood and are most active at night, thus bites are more likely to appear where the skin is exposed.

Bed bugs must eat at least once every 14 days in order to reproduce and breed, although they can go months or even years without eating.


Bite of a mosquito

Only female mosquitoes bite, and contact must persist at least 6 seconds for enough insect saliva to enter the bloodstream and induce a reaction.

Mosquito bites resemble red lumps in the center with a puncture wound. If a person is extremely sensitive, they may get welts or larger elevated areas.

Because of how the immune system reacts to mosquito saliva, the bites itch.

Mosquitoes are most likely to bite between sunset and daybreak, when it is dark. Mosquitoes may be attracted to carbon dioxide, human sweat, and warmth.


Differences in bite sizes

Mosquito bites and bed bug bites have varied effects on a person’s skin and in other ways.


Bites from bed bugs frequently appear in clusters and follow a unique pattern, such as a line or a zigzag. Bites are most common in regions where a person exposes themselves while sleeping.

Mosquito bites, on the other hand, tend to be solitary and emerge at random on portions of the body that aren’t covered by clothing.

Time to react

Bed bug bites are usually not felt, and symptoms can appear hours or days later. Symptoms usually go away within a week or so if there is no further discomfort.

Mosquito bites, on the other hand, can be itchy and apparent right away. They usually improve within a day or two.


Mosquito bites can cause dangerous infections in addition to itching and irritation. These diseases kill more than 725,000 individuals each year, according to the National Institutes of Health (NIH).
