Wasps are interesting animals that have a bad reputation for being annoying and mean. Besides their stingers, though, they have complex bodies that let them live in a wide range of places. Finding out how long wasps can live without food and water is an interesting part of their survival. We’ll look at the answer to this question and the things that affect how long wasps can go without eating or drinking in this article.
An Overview of Wasp Biology
There are over 30,000 identified species of wasps in the world. They are divided into two main groups – solitary wasps and social wasps. Solitary wasps live alone and do not form colonies, while social wasps like yellowjackets and hornets have complex, hierarchical colonies with queens, workers, and drones.
All wasps are carnivorous and get nutrition by hunting other insects, spiders, and sometimes even small vertebrates They paralyze their prey using venom and bring them back to feed their larvae Adult wasps get energy from carbohydrate-rich fluids like nectar and sap. Their mouths are designed for chewing and lapping up liquid meals.
Wasps do not maintain internal water reserves in their bodies. They meet their water needs by drinking from water sources like dew, droplets, ponds, and even moisture from fruits. Access to water is especially important for wasps that build paper nests, as they use water to make the paper.
Factors That Influence How Long Wasps Can Go Without Food and Water
Several factors impact how long a wasp can survive without food and water:
-
Species – Different wasp species have different bodies and behaviors that affect how well they can handle being hungry and thirsty. Solitary wasps may be able to survive longer than social wasps that are used to eating regularly.
-
Age – Adult wasps can withstand lack of food and water better than developing larvae that need nutrients to grow and metamorphose. Older adult wasps also fare better than younger ones.
-
Weather – Warm and humid conditions reduce water loss from a wasp’s body, enabling it to survive longer without water. Cold weather accelerates dehydration and starvation.
-
Activity: Wasps that are active use up their food and water stores more quickly than ones that are not active. Wasps save resources by being less active when there isn’t enough food or water.
-
Fat Reserves – Wasps that have higher fat content in their bodies at the beginning of starvation can live longer than those with lower reserves.
-
Nesting Habits – Social wasps benefit from food sharing when resources are limited. Solitary wasps lack this backup. Underground nests also help conserve moisture compared to exposed aerial nests.
The Maximum Starvation and Dehydration Survival Time for Wasps
Based on their biology and the above factors, most wasps can only survive a maximum of about a week without food and water. However, some exceptions have been observed:
-
In lab tests, solitary wasps like cicada killers and digger wasps have been able to go 15 to 20 days without food. Their solitary nature and nesting habits help conserve resources.
-
Queens and hibernating wasps can live for 30-45 days without eating or drinking. Queens have large fat reserves to founding new colonies while hibernating individuals minimize activity.
-
Hornets and yellowjackets typically succumb within 4-6 days without nutrition and water. Their high activity levels and reliance on food sharing deplete reserves quickly.
-
Larvae and younger wasps only last for 2-3 days due to their greater nutritional needs for growth and development.
While wasps are adapted to occasionally deal with food and water scarcity in the wild, prolonging the situation beyond a week usually leads to death. Their high metabolism, lack of reserves, and water needs make them vulnerable. Next time you come across a wasp, appreciate the intricate balance it maintains to stay energized and hydrated!
How Wasps Optimize Survival When Food and Water Are Scarce
When facing starvation and dehydration, wasps engage in specialized behaviors to prolong survival:
-
They reduce activity to a minimum to conserve energy and water reserves in the body. Only essential flights are made.
-
Social wasps share any scarce food finds equitably throughout the colony. This increases the chances of survival of all members.
-
Wasps derive water from non-liquid sources like nectar, body fluids of prey, and moisture in rotting fruits.
-
They move larvae and eggs to protected spots in the nest to ensure the next generation survives.
-
Solitary wasps seal up their underground nests to prevent moisture loss. Some even build nests near water sources.
-
When water is extremely limited, wasps scavenge moisture from leaves, grass, and soil. The humidity is absorbed through the thin exoskeleton.
-
Queens and hibernating wasps dig deeper and insulate their hibernation spots against cold temperatures that accelerate dehydration.
Through these adaptive behaviors, wasps can stretch their survival time by a few extra days during harsh conditions. However, they can only persist for so long without the basic requirements of food and water.
Signs of Starvation and Dehydration in Wasps
When wasps start experiencing the effects of starvation and dehydration, you may observe some of these signs:
-
Increased aggression and stinging behavior as they desperately search for food.
-
Lethargy, reduced flying ability, and worms-like crawling on the ground due to weakness.
-
Shriveled and dried out abdomen due to loss of fat reserves and water.
-
Cannibalism in social wasp colonies – adults start feeding on eggs and larvae to gain nutrition.
-
Loss of color vibrancy and a dull, faded appearance.
-
Strange behaviors like aimless wandering, lack of alertness, disorientation, and tremors from muscle spasms.
-
A high mortality rate, with dead wasps found near the nest.
These symptoms indicate the wasps are nearing the end of their survival capacity due to lack of food and water. Providing them access to suitable nutrition and hydration sources at this stage can sometimes revive them. But extended deprivation almost always leads to death.
In Closing
The fact that wasps rely completely on external sources for their water and energy needs makes them vulnerable when these resources become scarce. Their bodies are not designed to go for prolonged periods without food and water. However, wasps make the most of their anatomy and behaviors to stretch their survival for as long as possible, often lasting for a week or more. Their ability to adapt to challenges in the environment makes them masters of survival, despite the limitations. Watching a wasp battle the odds stacked against it can make us appreciate the ingenuity of natural selection in creating species specialized for specific niches.
Wasp Lifecycle
- 1. Eggs: Queen wasps will come out of hibernation after winter, having already mated and laid eggs the previous year. Or, they’ll make a colony the same spring they fertilized. It gives her energy to find and build a nest, so she eats. [11] Egg pods are built inside the nest so the queen can lay her eggs.
- 2 Larva: Once the eggs hatch, the nest’s cells will be filled with tiny larvae that look like bulbs. Sugars brought to these larvae by sterile worker bees are still being eaten by them. It will take these larva another two weeks to keep growing outside of their skin. [12] .
- 3: The pupa will wrap itself in a paper-thin cocoon and grow for another week after the two weeks of feeding. [13] .
- 4 Adult: When adult wasps come out of their cocoons, they take care of the nest, feed the larvae, and then fly off to mate. All the worker wasps will die by winter, and the queen will hibernate until the cycle starts again in the spring. [14] .

How long do wasps live indoors?
- 1 Solitary wasps die quickly if trapped indoors. They probably won’t make it more than a few days without a good food source (since they almost always hunt for food) or access to water. If you only have one buzzing around, you might be able to put the old shoe away and let nature take its course. [3] .
- 2 Wasp nests die quickly indoors. Most of the time, colony wasps get their food from sugars and pollination. The colony will start to die if they can’t get sugar quickly. Because of this, you can leave a wasp nest alone if it’s inside, but you shouldn’t ignore it if the wasps don’t seem to be leaving or dying. It could mean that they can get food and water somewhere. Depending on the species and the time of year, some wasps can go for a while without eating. Their metabolism can be slow enough to keep them going longer than usual. If you don’t feed a worker wasp that has just eaten and it’s fall, it will live a little longer. [4] A hibernating queen can live several weeks without food. During this time, their metabolism is very slow, so whatever they eat in the fall usually stays in their bodies longer. Still, if the temperature suddenly rises, they might wake up early from hibernation, which can make them lose their food. [5] .
- 3 Months can go by before a nest forms inside and outside. Wasps like to put their nests up high, where they can’t be seen by other animals. It likes to nest in the corners of roofs and gutters, and since it likes to chew wood, it can also make nests in walls. These nests can be very annoying because wasps can easily get in and out of them and are safe from cold weather.

Can a wasp live without food or water?
Paper wasps can live a while without food or water. Yellow jackets seem to last a day or so.
Can a wasp die from starvation?
Wasps don’t store food for the winter like bees do, so by late October or early November, most adult wasps have already died of hunger. Oct 29, 2024.
How long can a wasp live trapped in a container?
The primary variable that will predict how long a wasp will live is if it has a food source. If a wasp is trapped indoors with a food source, it can live for months. If it has no food source, it’ll likely last a few days. Some wasp species are able to survive longer without food than others.
