If You Spot These Mysterious Black Dots in Your Kitchen, Here’s What to Do

A concerned mother recently took to Facebook, seeking help after discovering strange black specks scattered throughout her home. She shared photos of the peculiar marks found on her skirting board, wallpaper, and floors, asking if anyone had seen something similar.

“Does anyone know what this could be?” she asked. “These marks just showed up over the past week on the skirting board in my dining room. I’ve also noticed them on my wallpaper and even on the floor, which I mop every single day! They’re not raised or rough—it almost looks like paint splatter, but I know it’s not paint.”

Within minutes, responses flooded in, and a common theory quickly gained traction: spider droppings.

Followers of the cleaning influencer Mrs. Hinch were quick to diagnose the issue. “It’s that time of year—spiders are leaving their droppings everywhere,” one user commented. “Dettox spray works well for cleaning it off.” Another chimed in, “Yep, that’s spider poo! I see the same thing on my window sills after they eat flies.” Many others agreed, though some debated whether the marks could be from flies instead. Still, one user insisted, “There’s no doubt about it—that’s definitely spider poop!”

But is this really the case? Do spiders leave droppings, and could they really be causing these dark stains?

What Experts Say About Spider Droppings

According to pest control experts, spiders do leave droppings, though they might not look as one would expect. Unlike the solid waste of other pests, spider droppings have a thick, liquid-like consistency. They often resemble small ink stains or dark splatters on walls, floors, and other surfaces.

The appearance of spider droppings can vary depending on the species, making them harder to identify for those unfamiliar with them. However, they generally appear as tiny, irregular black or brown spots, sometimes even gray or white. Since they are more liquid than solid, they tend to create unsightly stains, especially if they accumulate over time.

Spiders typically inhabit dark, quiet corners where they can spin their webs undisturbed. As a result, their droppings are commonly found beneath webs, in room corners, on ceilings, or along baseboards where cobwebs gather. Over time, these small stains can become more noticeable, making them difficult to clean, especially if left unattended.

Are Spider Droppings Harmful?

One of the biggest concerns homeowners have is whether spider droppings pose any health risks. While the idea of spider poop may be unappealing, experts reassure that it is not hazardous. Research suggests that spiders do not transmit diseases through their waste, even if they consume infected insects. That said, handling it with care is always a good idea.

Like any waste, it’s best to treat spider droppings as potentially unhygienic. When cleaning, wear gloves and wash your hands thoroughly with soap and water afterward. Fresh droppings can be easily wiped away with a damp cloth and a general household cleaner. However, dried stains may be more stubborn, requiring extra scrubbing or specialized cleaning solutions. In some cases, older stains might leave a faint yellow residue, particularly on porous surfaces.

How to Prevent Spider Droppings in Your Home

Cleaning the droppings is one thing, but preventing them from returning requires addressing the spiders themselves. If you’re seeing spider waste, chances are the culprits are still nearby.

The first step in managing a spider problem is to maintain a clean and clutter-free home. Spiders are attracted to undisturbed areas where they can weave webs and hunt for prey. Regular dusting, vacuuming, and cobweb removal can significantly reduce their presence.

It’s also important to check for potential entry points, such as small gaps in windows, doors, or vents. Sealing these openings can help keep spiders from sneaking inside. If the issue persists, several methods can help keep them at bay. Many homeowners swear by natural repellents, such as spraying diluted white vinegar or essential oils like peppermint, which spiders reportedly dislike. However, for more significant infestations, professional pest control services can provide the most effective and long-lasting solution.

Final Thoughts

If you’ve recently noticed mysterious black dots around your home, there’s a good chance spider droppings are to blame. While not harmful, these marks can be unsightly and difficult to clean if left for too long. Regular cleaning, removing webs, and sealing off entry points can help keep spiders—and their droppings—out of your home.

As for the mother who first raised the question on Facebook, she likely received more advice than she expected. From Dettox spray recommendations to debates over whether it could be fly droppings, one thing became clear: she wasn’t alone. Spider droppings may not be something people talk about often, but for many homeowners, they are an all-too-common nuisance. While the thought of spiders lurking in your home might not be pleasant, taking proactive steps can ensure those pesky black marks don’t return.
