When the warm weather hits, so do the mosquitoes. These pesky insects are more than just an outdoor nuisance, they can follow us inside, buzz around our bedrooms, and leave us with itchy bites and serious health concerns. One of the most common questions we hear at ohDEER is: How long do mosquitoes live?
In this blog, we’re answering that and other frequently asked questions about mosquito lifespans, including how long mosquitoes live indoors, how long they can live without blood or food, and how long mosquitoes might survive in your home. Let’s dig into the science, and share how you can keep your yard and home mosquito-free with safe, effective, all-natural mosquito control.
The average mosquito lives anywhere from 2 to 4 weeks, depending on the species, environment, and whether it is male or female. According to the Centers for Disease Control and Prevention (CDC) and American Mosquito Control Association (AMCA), male mosquitoes typically live about one week, while female mosquitoes can live several weeks or longer under ideal conditions.
Why the difference? Male mosquitoes feed only on nectar and plant juices. Once they mate, their biological purpose is complete, and their lifespan ends shortly after. Female mosquitoes, on the other hand, require blood to develop eggs and can lay hundreds of eggs during their lifetime. They also have stronger survival instincts and are more persistent in seeking out food sources.
When a mosquito finds its way into your home, you might expect it to die off quickly, but that’s not always the case.
So, how long do mosquitoes live indoors? If a female mosquito enters your house and has access to standing water and warmth, she could survive up to a month or more. Indoor environments tend to be more stable than outdoors, with consistent temperatures and fewer predators, allowing mosquitoes to extend their lifespans.
A study published in the Journal of the American Mosquito Control Association found that female mosquitoes kept in laboratory conditions (a controlled indoor environment) survived for up to 56 days. While your home isn’t exactly a lab, it’s not uncommon for a mosquito to survive inside for several weeks, especially if it has access to water and can feed on human or pet blood.
Many people believe that mosquitoes can’t live long without blood, but that’s not entirely true.
How long do mosquitoes live without blood? It depends on the mosquito’s sex. Male mosquitoes don’t feed on blood at all, they survive on nectar and other plant sugars. Female mosquitoes, however, need blood to produce eggs, but they can still live for days or even weeks without it.
Female mosquitoes can survive without a blood meal by feeding on nectar or fruit juices. But if they’re ready to lay eggs and don’t get blood soon, their reproductive cycle halts. In general, a female mosquito can survive 4 to 5 days without blood, depending on environmental conditions and available sugar sources.
Let’s clarify what “food” means for a mosquito. For male mosquitoes, food consists of plant nectar, honeydew, and other sugary substances. Even though they don’t want your blood, they can be attracted to scents emitted by your body. For females, food can include both sugar sources and blood.
So, how long do mosquitoes live without food? If deprived of all food sources, sugar and blood, mosquitoes won’t last long. Most mosquitoes will die within a few days (2–4 days) without any source of nourishment.
However, if they have access to sugar but not blood, females can live longer, although they won’t be able to reproduce. And if they’ve already taken a blood meal, they can use that energy to survive a little longer while seeking another meal or laying eggs.
In short:
If a mosquito enters your home, especially a female mosquito, she may live longer than she would outdoors. How long do mosquitoes live in your house? That depends on a few factors:
In a typical indoor environment with all of the above, a mosquito can live anywhere from a few days to several weeks, with females surviving the longest. The World Health Organization (WHO) notes that some mosquito species, like Culex pipiens, can even overwinter inside homes, entering a dormant state and re-emerging in spring.
Several additional factors influence how long mosquitoes live:
There are over 3,500 species of mosquitoes worldwide. Lifespans vary significantly. For example:
Mosquitoes thrive in warm, humid environments. Rain can create breeding grounds, but extreme heat or drought can shorten lifespans due to dehydration.
Mosquitoes outdoors face threats from predators (like birds, bats, and dragonflies) and pathogens. Indoors, they’re more likely to be killed by a human with a fly swatter or vacuum, unless they go undetected. How to attract mosquito eating birds.
Yes, unfortunately. If a female mosquito finds standing water indoors, she can lay 100–300 eggs at a time. The eggs can hatch in just a couple of days, making indoor infestations a real concern. Indoor breeding spots include shower drains, toilets, sinks, pet bowls and flower vases.
Knowing how long mosquitoes live, and how long they can survive in your home, is the first step. Here are some quick tips to prevent and eliminate mosquitoes indoors and out:
So, how long do mosquitoes live? It depends, but in the right conditions, they can live surprisingly long. Female mosquitoes, especially, are survivors. They can live for weeks, even months indoors, and lay hundreds of eggs if given the chance.
