How Long Do Spiders Live?
Here in Upland, CA, spiders are a common sight. And whether you’re a self-proclaimed arachnophobe or not, the reality is that seeing them regularly will make you wonder, “how long do spiders live?” And perhaps more importantly, why are you seeing so many spiders, and does their presence point to a deeper pest problem in your home?
At ProCraft Pest Control, we've helped countless homeowners in San Bernardino County manage pesky infestations, including spiders.
Below, we'll answer your burning questions about common spiders' lifespans, explain why recurring sightings may indicate an underlying issue, and share solutions to keep your home pest-free.
How Long Do Spiders Live?
The lifespans of spiders vary greatly depending on the species. While most live for one to two years, some can survive much longer, particularly in captivity.
Common house spiders (like those found in the majority of our Upland homes) typically live around one to two years.
Tarantulas, a favorite exotic pet, can live 25 years or more in controlled environments.
Some desert-dwelling spiders can survive several years without food, a testament to their resilience.
Interestingly, many species of spiders can go months (or even years) without a meal, especially when food sources like insects or small bugs are scarce. This remarkable adaptability is a survival mechanism but it can also make them longer-term residents in your home if you don't address the root cause of their presence.
Why Are There Spiders in My Home?
A few occasional spider sightings don’t necessarily mean you have a big problem. Spiders are natural predators that control other pest populations.
However, regular spider activity could signal a larger infestation. Here's why they stick around:
Plenty of Food: If spiders are thriving in your home, it’s likely because there’s an abundant food source—including pests like flies, ants, or roaches.
Low-Traffic Areas: Webs tend to show up in corners, basements, attics, or behind storage items where there’s little human activity.
Shelter: Spiders enter homes seeking warmth and security, especially during cooler months.
Are Spiders Dangerous?
While the overwhelming majority of spiders are harmless to humans, their presence can be unsettling. Out of the 1,200 spider species in the U.S., only a handful pose any risk to people.
Black widows and brown recluses are the two most venomous types found in California. Luckily, they are rare and are unlikely to bite unless provoked.
Statistically, seven people per year in the U.S. die from spider bites, meaning the odds of a life-threatening encounter are extremely low.
However, if you spot a potentially harmful spider or suspect a bite, consult a professional like us to assess the situation safely.
Despite this, if spiders continuously make themselves at home, it’s important to identify what’s attracting them.
The most common reasons for a sudden onslaught of spiders include hidden pest infestations (like roaches or ants) providing a food supply, as well as a large number of dark, undisturbed spaces that haven’t been cleaned or decluttered regularly. Similarly, openings in windows, doors, or screens allow pests (and spiders) easy access to your home.
Key takeaway here? Repeated spider sightings should serve as a red flag, alerting you to tackle bigger problems that could worsen without intervention.
