Imagine, for a moment, that it’s a sunny Saturday morning in San, Jose, CA, and you’re finally tackling that garage cleanout that’s been on your to-do list for months.
You move a box out of the way, and there it is: a spider. And it’s a big one.
So do you abandon your cleanout ambitions once more, or work around the eight-legged intruder? Are all spiders venomous, or is this little guy nothing to worry about? Do you need to call pest control for help?
These are questions we hear all the time at Banner Pest Services. While we can’t tell you whether you should hold off on cleaning out your garage because of some arachnophobia, we can debunk some common myths about venomous spiders in California (and give you advice on what to do about them in your home).
Are All Spiders Venomous?
Here’s the short answer to the big question. Yes, all spiders are venomous—but not all are dangerous to humans.
Spiders use venom to paralyze or kill their prey, which usually consists of insects. However, the venom of most spiders is not potent enough to harm humans. Not only that, but many spiders have fangs that are too small to puncture human skin. This means the majority of spiders you come across are completely harmless to you.
Still, there are exceptions. A small number of spiders have venom that is potent enough to cause serious harm to humans. These types include black widows and brown recluses, which we’ll discuss later.
Benefits of Spiders in Your Home
While spiders might not be your favorite roommates, they’re not all bad. Here’s how they actually benefit your household:
- Pest Control: Spiders eat insects like flies, mosquitoes, and cockroaches, reducing the number of pests in your home.
- Eco-Friendly Helpers: By controlling insect populations naturally, spiders reduce the need for chemical pesticides.
- Indicators of a Healthy Ecosystem: The presence of spiders usually signals a balanced environment.
The benefits of spiders are clear! But, if spiders are overstaying their welcome, we completely get it. A spider-free home is a peaceful home for most people, which is why we’re here to help.
Spiders to Watch For in San Jose and Surrounding Areas
Most spiders in the San Jose and Bay Area regions are harmless, but there are a few species you should be aware of:
Black Widows
Black widows are a glossy black with a telltale red hourglass marking on their abdomen. They’re most commonly found in woodpiles, under decks, and in dark corners of garages or sheds.
Bites from black widows can cause muscle cramps, difficulty breathing, and severe pain. Immediate medical attention is important if you suspect a black widow bite.
Brown Recluses
Brown recluses are brown with a violin-shaped marking on their body. These spiders prefer dark, undisturbed areas like closets, attics, or under furniture. Their bites can result in skin ulcers and necrosis if not treated promptly.
Jumping Spiders
Small and hairy, jumping spiders are often black or gray, with striking patterns. They’re found in gardens, windowsills, or even indoors. For the most part, their bites are harmless but can cause mild irritation.
Wolf Spiders
Wolf spiders are large and hairy, so much so that they are often mistaken for tarantulas. They’re found near ground level, often in basements or garages. Their bites are mildly painful but not medically significant.
How to Keep Spiders Out of Your Home
If you’d like to avoid these creepy-crawly house guests, here are some tips that work:
- Declutter: Spiders love hiding in undisturbed piles of boxes, wood, or clothing.
- Seal Entry Points: Repair cracks and gaps in windows, doors, and walls.
- Use Outdoor Lighting Strategically: Bright lights attract insects, and where insects go, spiders follow.
- Regular Cleaning: Vacuum corners, under furniture, and other areas spiders may hide.
- Hire Professionals: We offer effective, family-friendly spider control services in San Jose and throughout the San Francisco Bay Area.

Did You Know?
There are nearly 50,000 spider species worldwide, but only a handful pose any real danger to humans. Even in the U.S., fewer than three people die each year from spider bites, and most of these cases involve children. Spiders, it turns out, are more about pest control than posing risks to humans.
FAQ
Do all spiders bite humans?
No. Most spiders don’t bite humans unless they feel threatened, and even then, many species lack fangs strong enough to penetrate the skin.
What should I do if I find a spider?
If it’s non-threatening, you can release it outdoors. For frequent encounters or suspected venomous species, reach out to professionals like Banner Pest Services.
Can I prevent spider bites?
Yes, wear gloves and long-sleeved clothing if working in areas like attics or woodpiles, and always shake out shoes or clothing before use.
When should I call a pest control service for spiders?
If you’re noticing an increase in spider activity, especially from potentially venomous species, it’s time to call in support.
