Do mosquitoes die after they bite you?

“Do mosquitoes die after biting you? I’m sure it’s the same one lurking in my room every night.” 

No, a mosquito does not die after biting you. Unlike a honey bee, which loses its barbed stinger and dies, a mosquito uses a long, needle-like mouthpart called a proboscis. It slips in, draws blood, slides back out, and flies off ready to bite again.

Only the females bite; they need a blood meal to develop their eggs. Males live on flower nectar and never bite at all.

How many times can a mosquito bite you? 

There's no fixed limit. A female keeps feeding until she's full, and if she gets interrupted (a slap, a swat, a sudden movement), she'll often land again to finish the meal. After feeding, she rests for a few days, lays a batch of eggs, then starts looking for her next meal.

If bites are a regular nuisance, there's no doubt a breeding source close by, usually standing water in a gutter, planter saucer, or pet bowl. A targeted mosquito control plan can help protect you against annoying bites.
