Do Wasps Poo And Pee? 10 Facts About Wasp Poop

Wasps poo and pee at the same time. Like insects, they release both poo and pee at the same time. The result is a yellow substance that is released from beneath the abdomen.

Wasps have a healthy digestive tract. Excrements released by wasps are typically pollen and plant byproducts.

Their digestive tract is mostly adapted to absorb carbohydrates. Various forms of sugar are absorbed by the digestive tract of wasps.

Raw pollen and honeydew are the sole foods or sugars wasps eat. But not all of this matter is processed and some are turned into poop.

Do Wasps Poo And Pee?

Wasp has a complex connection to excrements. Like all insects, wasps need to defecate. Otherwise, poop buildup would cause health issues for wasps.

Some wasps can even detect poop while flying. Parasitic wasps use poop or droppings to guide themselves to their hosts.

Every living insect has to poo. Insects don’t separately release poo and pee. Like all insects, wasps release a yellow soft substance that is a combination of poo and pee. The more sugars wasp eat, the more poo they release.

Wasps need food to grow and use for energy. Their digestive tract absorbs sugars and converts them to energy. Waste products of poop are the direct result of food or nutrients that cannot be digested.

All of the surplus material that can’t be digested needs to be released by wasps. This might not be as frequent as in other species in the animal world.

However, excretions of wasps happen constantly. While there aren’t too many studies showing how wasp poop, this information closely resembles the way bees poop.

Bees and wasps are typically observed by beekeepers, the main source of information on how wasps poop.

Do wasp larvae and pupae Poo And Pee?

Wasp larvae and pupae don’t poop. It’s only adult wasps that poop. Wasp larva also eats differently and it lacks the mature digestive tract of adult wasps.

Pupae don’t leave the nest. This can also be an indicator of why young wasps don’t poop. Adult wasps only poop outside of the nest to stay away from bacteria and to generally keep the nest clean.

What Does Wasp Poop Look Like

Wasp poop appearance varies depending on the food wasps consume. Its size also depends on the size of the adult wasp. The large the wasp’s abdomen, the larger its poop is.

Wasp Poop


Wasp poop varies in color. Most wasp poop is yellow. In other cases, wasp poop can be white or brown. The poop has a viscous thick consistency.

Its consistency is affected by what wasps eat. At the same time, the consistency of the poop also affects its color. The thicker the poop is the more yellow it looks.


The size of excretions varies according to the wasp’s size. Most wasp’s poop is at least 0.0025 inches long. It can be seen easily in areas with multiple wasps.

The largest wasp poop is the poop of the queen wasp, the largest type of wasp. Queen wasps can make poop at long as 0.0050 inches.

Chemical composition

Urea is the prominent chemical composition of wasp’s poop. This is a regular uric acid also excreted by humans. Uric acid is not toxic.

Is wasp poo dangerous?

Wasp poop isn’t toxic as it mainly contains urea. This uric acid of the poop is semi-liquid. It only turns to a liquid in animals that have separate organs for peeing and pooing. This is why wasps don’t need too much water for excretion.

How Do Wasps Poo?

Wasp poop by excreting undigested nutrients or other matter through a cesspool in the abdomen. Just like other insects, wasps need to poop. However, only mature wasps poop. Wasp pupae don’t poop. Queen wasps poop inside the nest while worker wasps clean up after the queen.

How Often Do Wasps Poo?

Wasps mostly poop in the summer. They become inactive in the winter when they go into hibernation and don’t poop at all.

A large number of wasps don’t survive winter. The highest chances of seeing wasp poop are in late spring and early summer.

Do Wasps Poo Inside Their Nests?

Wasps don’t poop insider their nests. They are clean insects that only poop outside of their nest. Wasps often leave their nests to poop.

These adaptations are considered of evolutionary nature. Eusocial wasps that live in large groups are subject to infections and microbial exposure through excessing pooping.

Wasp and other eusocial insects have adapted to avoid catching infections mainly by cleaning excrements from the nest as often as possible and by pooping outside of the nest.

Why do wasp poo on cars?

Wasp pooping on cars is one of the common problems that’s often mistaken for regular dirt. Not many people know how to identify wasp poop on a car.

Its yellow waxy nature sometimes makes it hard to remove from vehicles. Here’s are the top reasons wasp poop ends up on cars more than on other surfaces.

Cars get hot in the summer

Cars attract and radiate a lot of heat during the summer when parked in the sun. This extra heat is believed to attract wasps that feel more comfortable in the heat. W

asps also wait for good weather to get out of the nest to poop. This means the combination of warm weather and the heat released by cars attract wasps out of their nests more than other non-metal surfaces that don’t get as hot.

Proximity to nests

Many cars are parked on driveways. Some wasps nest in the ground and as soon as they exit the nest they see a car that allows them to poop on it easier. Wasps that live in nests attached to homes also live near cars.

Bright colors attract wasps

Bright colors such as yellow, pink, white, and light blue are all colors that attract a lot of insects. Wasps are no different.

They are often attracted by bright colors and this can be seen by the vivid-color flowers they are attracted to. Most wasps that poo on cars are attracted by their colors first. A bright color car acts as a magnet for insects.

How to clean poop?

Wasp poop can come off from cars but not as easy as regular dirt and dust. Wasp poop tends to stick to the car’s surface. This means cars need to be washed a bit more thoroughly as a result.

Soak the poop first

As with all types of dirt and grime that don’t come off easily, the car needs to be soaked properly. Pre-washing the car with water is the first step.

Apply wash soap

Liquid car wash soap then needs to be applied using a sponge and scrubbing the areas mostly affected by wasp pop. A potent car wash soap is needed for poop that’s been dried for more than a few days.

Use a pressure washer

Pressure washers are ideal for clearing wasp poop off a car. Rinsing the car with water from a bucket is an inefficient way of completely getting rid of wasp poop.

How To Prevent

You can also prevent wasp poop on your car instead of having to deal with a long car washing process.

Park the car in the garage

A car that sits in the garage is out of reach for most wasps. The car is less likely to be an attraction for wasps if it’s parked in the garage even when its doors are widely open. Alternatively, you can cover the car with a blanket to avoid having to deal with length washing-ups.

Park the car in a shaded spot

Heat radiating from cars parked in the sun may attract wasps. The best way to away cars from overheating is to park them in a shaded spot. Parking a car under a tree can prevent it from overheating and attracting wasps, particularly during the summer.


Wasps poo and pee similarly to all other insects. Research shows wasps are rather clean and this is an evolutionary characteristic, particularly among eusocial wasps that needed to stay pathogen-free when living together.

Most importantly, wasps need to poo to eliminate unprocessed matter they collect from flowers. Only adult wasps poo, similarly to bees. Most pooing happens in spring and summer.

Wasps don’t poo in the winter when they hibernate, unlike bees. 

Wasps poo and pee at the same time. The excrements are normally yellow but they can also be white or brown, depending on the type of food they consume. Wasps poo even when they don’t have access to much water.

Pooing wasps can cause trouble with cleanliness but not health problems as their poo isn’t toxic. One of the biggest issues caused by their poo is droppings on cars.

Wasps are attracted to bright-colored cars and to cars that radiate heat. You can avoid such problems by covering the car, keeping it in the garage, or parking it in a shaded spot where wasps don’t easily over it and when the car doesn’t heat up from the sun.
