what does spider poop looks like

how does Spider Poop actually looks?

While deep cleaning your home, most of you would have noticed black or dark spots around the corners.

If yes, then including you, your home is housing some spiders as well.

Black or Dark brown spotting is basically the spider poops. Moving on further, we will discuss them deeply. 

Spiders are invertebrate animals that live in almost every habitat on earth.

Only accept the highest mountains, oceans, and polar regions; there isn’t a place you will not spot a spider.

As per researches, they have even invaded the ocean edges.

All across the world, there are 43,000 identified species of spiders, which for some is a fascination while others a nightmare. 

Regardless of your love and hate for spiders, you can find them in every nook and corner of your space.

Either it is a cobweb/ spiderweb or spider poop displaying traces of their existence.

While everyone is easily familiar with the spiderwebs, how does a spider poop look is still a question? 

Several individuals often come up with a question like Do spiders poop?

What does spider poop look like? Are Spider poop infectious or dangerous?

Do Spiders Poop?

Like any other living creature, spiders also poop and excrete but it is somewhat unnoticed.

Or because anyone who eats would secrete waste, spiders do the same as well.

Also, because we don’t often witness spiders releasing themselves, the question of their pooping often stays.

Spider’s body has several structures called Malpighian tubules that function similarly to the human kidney.

These tubules release nitrogenous waste in the form of a liquidized poop.

However, like humans’ spiders don’t deposit feces and urine separately.

Instead, they deposit a combined waste (liquid) that they release from the anus. This waste is also called the Spider Poop.

What does Spider Poop look like?

Spider poop looks like feces or liquid drops. It is likely a viscous liquid with a black or dark appearance.

Their poop (dropping) is a little messy and is commonly found upon walls and other surfaces.

While the color of these droppings can vary depending upon species, you can commonly expect dark splats or drips.

Or in some other instances, the color of spider poop can range from shades of black, brown, white, or grey. 

For example, Tarantula's poop is large, waterier, and less viscous. It also dries and hardens quickly than other spider poops. 

Unlike one would picture, spider poop isn’t solid. It resembles a paint splatter.

While fresh poop is thick and liquidy inconsistency, when dried, it will become rough and patchy.

Spider droppings are mainly round, about 1/16 to 1/8-inch diameter. After drying, their color can change and become a little faded. 

Is Spider poop toxic?

In contrary to the pre-defined beliefs, Spider Poop is not toxic at all.

Although they can create a mess in the corners of your houses, researchers suggest that Spider dropping cannot harm humans. 

While several types of research and studies were performed, experts came to a confusing conclusion most of the time.

Spiders feed on insects that potentially contain deadly microbes and hundreds of pathogens.

However, once they secret waste, their poop is biologically free of any such microbes and pathogens. 

Is Spider dropping poisonous?

Does the fact confuse you? No problem, we have an explanation for that as well.

Scientists have speculated that Spiders have microbial inhibitors in their blood and venom.

These inhibitors kill the microbes and pathogens, transforming their poop into a non-toxic substance.

However, nothing from this information has been proven yet, and there are still researches going through.

Do Spider Pee? Do spiders Urinate?

Yes, like any other insects, Spiders Pee in order to remove nitrogen from their body.

However, unlike humans and other mammals, they don’t produce urine. 

Spider poop and pee at the same time in the form of a semi-thick liquid.

Also, while spiders do not produce urine, they do produce uric acid.

However, their uric acid is nearly solid and cannot dissolve in water.

Another important fact states that spiders cannot afford to lose as much bodily liquid (pee) as us humans. 

Several spiders can capably convert nitrogenous waste into dry guanine, a white powdery substance.

Guanine is one of the bases of Nucleic acids, and in Spider’s body, it works as effective camouflage.  

Where to look up for Spider Poop?

The chances of spotting spider poop are actually rare, though not impossible.

Spiders can survive days without food, have a slow metabolism, and thus their waste reliving is automatically rare.

However, there are a few places you can spot spider poop or its traces.

Spiders spend most of their time on their webs. While you can find these webs all around the house, most commonly look at the corners, arches, and joints.

Wherever you find a web below, look for spider poop underneath. 

Look at places that are often undisturbed and a little far away from human interference.

These can be cabinets, drawers, shelves, underneath the bed, behind the furniture, or inside cupboards on untouched clothes.

Though because Spiders aren’t arthropods, they, rather than choosing their latherin site, will poop anywhere randomly.

Do Spider Pooping cause stains?

If you clean the Spider Poop right away when it is still liquid and fresh, it will not leave back any stains.

Though if spider droppings are left behind, they will leave a pale-yellow stain behind on the surface.

Further, to understand why spider droppings leave stains behind, let’s first understand their digestion and secretion process. 

Why Do Spider Droppings Create Stains?

Spiders generally feed on solid food that commonly is insects.

However, do you they aren’t actually capable of ingesting and digesting solid food?

Yes, you read it right. Spiders lack teeth to bite, chew, or break down food;

however, filters in their guts ensure no solid food reaches their stomach. 

While spiders trap their prey, their venom paralyzes it.

These preys are still in the web, and further spiders wrap them up in their silk.

Thereafter, the digestion process moves forward in two different ways. 

First Way for spider digestion

Digestive enzymes of a spider are extremely powerful in the way that they can liquefy a prey’s tissues.

While most of the Spider’s club their digestive enzymes on their prey, it helps them conclude digestion outside their body.

Now once the prey is crumbled or liquefy, Spider simply sucks it like liquid.

Thus, in practical words, Spider transforms the solid food into liquid outside their body and then consumes it in the liquid state. 

While the food is partially digested even before consumption, the other half happens inside the spider body. Their stomach pumps the food deeper into their guts to further complete the digestion process. 

Second Way of spider digestion

Or, after paralyzing their prey, spiders use their fangs and inject digestive enzymes into the prey’s body.

It helps in digesting and liquefying the internal organs of the prey.

Further, spiders suck this liquid substance and easily digest it. 

In short, because spiders cannot have solid food, their digestive enzymes help them with the process.

These enzymes are so powerful that they complete half of the digestion process even before consuming the food (liquid). 

Now coming back to the question, Why Do Spider Droppings Create Stains?

The powerful digestive enzymes we discussed causes tough stains which are left underneath spider droppings (poop). 

How To Safely Remove Spider Poop?

The best way to clean Spider poop is right after they have pooped.

While the Spider droppings are still fresh and liquid, simply wipe them off with a dry or damp cloth.

However, it is not always easy to find and clean spider poop freshly right away. 

While one encounters spider poop in their houses, it is in dry and hard form.

Now removing the hard and dry spider poop with a damp cloth is not at all easy.

However, the process is not impossible as well. Here we have some quick and easy remedies for cleaning spider poop or droppings. Have a look:

How to keep spiders away from homes?

House spiders cause no harm to humans; however, keeping them is in no way pleasing.

You can easily get rid of them, and further, keep them from coming inside. 

Natural ways and home remedies to keep spiders away from home:

    • Spray it on cracks, crevices, windows, nooks, and corners of your house.
    • Also, spray it over empty spider webs and other potential spaces. 
  • Run leftover citrus and lemon peel on doorways and window grills.
    • Spiders absolutely hate the citrus smell and will never enter a space influenced by it.
    • You can also use citrus-inspired candles and sprays, for that matter. 
  • Crush strongly fragrant garlic and mix it with water.
    • Let the solution sit for some time. Now spray it on all nooks and corners of your house.
    • Spiders do not like the garlic smell and thus will not enter the space anytime soon.

  • Maintain regular cleaning. Spider-like to the house in dirty, untidy, and cluttered spaces. Homes that are cleaned regularly have fewer chances of spider breeding than dirty homes.
    • Make sure you clean your home on a daily basis, followed by deep cleaning every 15 days.
