Wasps are fascinating creatures that have a reputation for being pesky and aggressive. But beyond their stingers, they have an intricate biology that allows them to survive in a variety of environments. One aspect of wasp survival that sparks curiosity is how long they can live without basic necessities – namely food and water. In this article, we’ll explore the answer to this question and look at the factors that influence how long wasps can go without eating and drinking
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 variations in anatomy and behavior that affect their starvation and dehydration resilience Solitary wasps may survive longer than social wasps that are accustomed to regular food intake
-
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 rapidly deplete energy reserves and lose water compared to inactive ones. Wasps conserve resources by reducing activity when food and water are scarce.
-
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:
-
Solitary wasps like cicada killers and digger wasps have survived for 15-20 days without food in lab experiments. 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 emerge from hibernation after winter, already fertilized from mating the previous year. Or, they’ll make a colony the same spring they fertilized. She eats to get the energy to find and establish a nest.[11] Egg pods are constructed within the nest for the queen to lay her eggs.
- 2 Larva Once the eggs hatch, tiny, bulb-shaped larvae will occupy the cells of the nest. These larvae continue to feed on sugars brought to them by sterile worker bees. These larva will continue to outgrow their skin over the next two weeks.[12]
- 3 Pupa Once the two weeks of feeding have passed, the larva will wrap themselves in a paper thin cocoon and will grow for another week.[13]
- 4 Adult After emerging from their cocoons, adult wasps will take to maintaining the nest, feeding larva, and flying off to mate. By winter, all the worker wasps will die, and a newly fertilized 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. Without a proper food source (especially since they tend to hunt for their meals) or access to water, they’re unlikely to live beyond a few days. So, you might be able to put away the old shoe and just let nature take its course if you have a single one buzzing around.[3]
- 2 Wasp nests die quickly indoors. Colony wasps usually rely on sugars and pollination to keep themselves fed. If they don’t have quick access to sugar, the colony will begin to die. As a result, it’s possible to just leave a wasp nest alone if it’s completely indoors, but the nest shouldn’t be ignored if wasps don’t seem to be leaving or dying. It may mean they have access somewhere to food and water.
- Some wasps can actually survive a while without food! It depends on the species and the season, their metabolism can be slow enough to keep them kicking for longer than normal. A worker wasp who’s just eaten and has moved into autumn will live a little longer if deprived of food.[4]
- A hibernating queen can live several weeks without food. Their metabolism is extremely slow during this period, so whatever they eat in autumn usually lasts longer. That said, if the temperature rises suddenly, it may prompt them out of hibernation early, which can lead to them starving.[5]
- 3 A nest that forms both inside and outside can last months. Wasps like to build their nests in high places that are safe from predators. The corners of roofs and gutters are popular spots, and the species happens to be a fan of chewing wood, it can make nests form in walls. These nests can be really problematic, because the wasps have an easy means to get inside and out, and are protected from harsh temperatures.

How long does it take wasps to starve?
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?
Unlike bees, wasps don’t store food for the winter, meaning that most adult wasps die of starvation by the time Late October/ November rolls around.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.
