Imagine waking up one morning to find black dots appearing in your kitchen. That’s exactly what happened to one woman, and it left her feeling alarmed and puzzled. The dots seemed to appear out of nowhere – first on the kitchen tiles, then on top of the PC that was kept in the kitchen. Naturally, she wanted to find out what was causing this strange phenomenon.

Someone suggested that she might have a spider problem. But do spiders really leave solid excrement in the form of black dots? According to the Pest Guidance website, spiders’ excrement is actually thick and liquid, similar to ink stains commonly found on walls and surfaces. These droppings contain a mixture of food and other residual components that spiders release from their bodies.

Contrary to popular belief, spiders are not out to attack humans with their venomous fangs. In fact, professional pest control experts argue that other indoor pests, such as mice and flies, pose a greater threat to human health due to the potential for food contamination. While some studies have questioned the health benefits of spider droppings, it is important to note that they are not considered harmful.

But what about pathogens? Can spider droppings contain harmful bacteria that could pose a risk to human health? Research has shown that common human pathogens, including Staphylococcus spp., Streptococcus spp., Enterococcus spp., Salmonella spp., and E. coli, have been found in the excrement of flies. However, there is limited research on the microbiological residents of spiders and their droppings.

To shed light on this matter, Melissa Gaver-Wainwright, an entomology graduate student at Washington State University, conducted a preliminary study. She collected a fecal sample from a sterilized container and analyzed it for bacteria. Surprisingly, the spider feces had no detectable germs.

While these findings are intriguing, more research is needed to understand the bacterial composition of spider droppings. It remains unclear whether other species of web-building spiders would also have bacteria-free droppings or if different research methods would yield different results.

In the meantime, it is worth noting that controlling filth flies may be more important than controlling spiders when it comes to safeguarding our health. Spider droppings, on the other hand, are generally not a cause for concern when found indoors.

So, the next time you spot mysterious black dots in your kitchen, you can rest assured that spiders are unlikely to be the culprit. Instead, focus on maintaining a clean and hygienic environment to keep pests at bay. After all, a tidy kitchen is a happy kitchen!
