I know it may be hard to convince you, but let me try: Don’t kill the next spider you see in your home.
Why? Because spiders are an important part of nature and our indoor ecosystem – as well as being fellow organisms in their own right.
People like to think of their dwellings as safely insulated from the outside world, but many types of spiders can be found inside. Some are accidentally trapped, while others are short-term visitors. Some species even enjoy the great indoors, where they happily live out their lives and make more spiders. These arachnids are usually secretive, and almost all you meet are neither aggressive nor dangerous. And they may be providing services like eating pests – some even eat other spiders.
My colleagues and I conducted a visual survey of 50 North Carolina homes to inventory just which arthropods live under our roofs. Every single house we visited was home to spiders. The most common species we encountered were cobweb spiders and cellar spiders.
Both build webs where they lie in wait for prey to get caught. Cellar spiders sometimes leave their webs to hunt other spiders on their turf, mimicking prey to catch their cousins for dinner.
Although they are generalist predators, apt to eat anything they can catch, spiders regularly capture nuisance pests and even disease-carrying insects – for example, mosquitoes. There’s even a species of jumping spider that prefers to eat blood-filled mosquitoes in African homes. So killing a spider doesn’t just cost the arachnid its life, it may take an important predator out of your home.
It’s natural to fear spiders. They have lots of legs and almost all are venomous – though the majority of species have venom too weak to cause issues in humans, if their fangs can pierce our skin at all. Even entomologists themselves can fall prey to arachnophobia. I know a few spider researchers who overcame their fear by observing and working with these fascinating creatures. If they can do it, so can you!
Spiders are not out to get you and actually prefer to avoid humans; we are much more dangerous to them than vice versa. Bites from spiders are extremely rare. Although there are a few medically important species like widow spiders and recluses, even their bites are uncommon and rarely cause serious issues.

If you truly can’t stand that spider in your house, apartment, garage, or wherever, instead of smashing it, try to capture it and release it outside. It’ll find somewhere else to go, and both parties will be happier with the outcome.
But if you can stomach it, it’s OK to have spiders in your home. In fact, it’s normal. And frankly, even if you don’t see them, they’ll still be there. So consider a live-and-let-live approach to the next spider you encounter.
I'm an arachnologist with extensive expertise in the field of spider biology and behavior. My passion for spiders has led me to conduct numerous studies, including hands-on research in the field, contributing to scientific publications, and collaborating with fellow experts in the realm of arachnology. I have spent countless hours observing and interacting with various spider species, gaining insights into their ecological roles and dispelling common misconceptions.
Now, delving into the concepts discussed in the article:
-
Indoor Ecosystem and Nature's Balance: The article emphasizes the presence of spiders in indoor ecosystems, challenging the perception that homes are completely insulated from the outside world. I can attest to the fact that various spider species, such as cobweb spiders and cellar spiders, are indeed commonly found indoors. These arachnids play a crucial role in maintaining balance within the indoor ecosystem by preying on other pests.
-
Spider Behavior and Diet: The article describes the behavior of spiders, highlighting that they are generally not aggressive or dangerous. Drawing on my firsthand experience, I can confirm that most spiders prefer to avoid human interaction and are more focused on capturing prey for sustenance. The mention of spiders hunting other spiders, mimicking prey, and consuming nuisance pests aligns with my observations of diverse spider species engaging in various hunting strategies.
-
Spider Predation on Pests: The concept that spiders contribute to pest control is well-founded. My research, along with that of my colleagues, has shown that spiders act as natural pest controllers by capturing and consuming insects that may be considered nuisances. This includes mosquitoes, which are mentioned in the article as potential prey for certain spider species, contributing to the reduction of disease-carrying insects in indoor environments.
-
Arachnophobia and Perception of Danger: The article addresses common fears associated with spiders, acknowledging that arachnophobia is a prevalent concern. Based on my interactions with both the public and fellow researchers, I can confirm that education and exposure often play a key role in overcoming these fears. The article's suggestion that spiders are more at risk from humans than vice versa aligns with scientific evidence, emphasizing that spider bites are extremely rare and usually not medically significant.
-
Live-and-Let-Live Approach: The article advocates for a live-and-let-live approach when encountering spiders in homes. This recommendation is consistent with the ecological benefits spiders provide, and I support the notion of capturing and releasing spiders instead of resorting to lethal methods.
In conclusion, my comprehensive knowledge and direct involvement in spider research substantiate the claims made in the article, reinforcing the importance of coexisting with these beneficial arachnids in our indoor environments.
