Arachnophobia

You spot a spider in the room. Someone else barely notices, but you can’t stop thinking about where it might go. Even after it’s gone, going back into that room feels hard.

Arachnophobia is an intense fear of spiders. Fear of spiders is one example of a specific phobia—a fear linked to a particular thing or situation. NIMH

You can dislike spiders without having a phobia. What matters is how much fear you feel and how much it affects your life.

If you’re looking for insects rather than spiders, our entomophobia article covers that fear, including sensible precautions around bites and stings.

What does it feel like?

Fear can show up in your body as well as your thoughts. Your heart may pound, your hands may shake, or your stomach may churn. Some people feel dizzy or want to leave at once. These are general phobia symptoms; people experience them in different ways. NHS

You may know that the situation is unlikely to hurt you and still feel scared. Knowing the facts doesn’t always make the feeling stop.

What can bring the fear on?

Seeing a spider is the obvious example. Worrying about seeing one can also bring anxiety. NIMH describes both fear during an encounter and worry about future encounters. NIMH

For example, you might hesitate before opening a shed, or avoid a room where you saw a spider earlier. Pictures can also be upsetting for some readers, which is why this page has no spider photos. The NHS advises taking care when searching online for phobia information because unexpected images can be difficult. NHS

How is a phobia different from disliking spiders?

Not wanting to pick up a spider doesn’t tell us much on its own.

A therapist looks at the bigger picture: how strong the fear is, how long it has lasted, how much you avoid, and whether it causes serious upset or gets in the way of life. They also consider the actual danger. Merck Manual

Imagine skipping a camping trip you wanted to join because you can’t stop worrying about spiders. Or leaving part of your home unused after seeing one there. These are examples of how fear might affect someone’s choices, not signs that prove a diagnosis.

Is it fear, disgust, or both?

“I’m scared it will hurt me” and “I can’t stand the thought of it near me” aren’t quite the same feeling. Fear concerns a threat; disgust is more of a strong sense of revulsion. Both can be relevant to spider fear.

In one small study, women with spider phobia showed greater disgust sensitivity than women without it, and disgust responses were related to spider fear. This supports taking disgust seriously, but doesn’t prove it causes arachnophobia or that everyone experiences it. The study involved women only. Spider fear and disgust study

You might tell a therapist, “I’m not mainly worried about a bite. It’s the thought of one touching me.” That’s useful detail, not something you need to translate into a medical term.

Why am I so afraid of spiders?

There may not be a single event you can point to. Research on specific phobias suggests that life experiences and inherited influences can both play a part. A frightening encounter or a family history of anxiety may contribute, but neither explains every person’s fear. NIMH

You don’t need to find a perfect explanation before asking for help.

Why does the worry continue after the spider is gone?

Before looking at treatment, it can help to notice what happens after an encounter. Perhaps someone has removed a spider, but you still want them to check the room again. Or you keep avoiding the cupboard where you saw it. These are hypothetical examples, not signs that prove a diagnosis.

Mind describes avoidance and rules intended to prevent feared encounters as possible “safety behaviours.” They can feel helpful while making a phobia harder to overcome. That doesn’t make sensible wildlife precautions wrong, or mean every request for help is a problem. Mind

“Once a spider has been dealt with, why do I still feel unable to use that room?” is a useful question for an appointment. This page doesn’t ask you to stop checking abruptly or handle a spider yourself.

What can help?

Talking therapy is the main treatment for phobias. Cognitive behavioral therapy (CBT) helps people work on patterns of thought and behavior linked to fear. Exposure therapy is one method used to help people face what scares them within a treatment plan. NIMH

A research review found strong support for exposure therapy while calling for better evidence on longer-term results. It isn’t a promise that everyone will improve at the same pace. The Lancet Psychiatry review

If you’re interested in therapy, you can ask how it works before agreeing to anything. Tell the therapist what feels hardest and what you’d like to be able to do more easily.

What do spider-specific studies tell us?

A 2019 randomized trial assigned 100 people with spider phobia to either technician-assisted virtual-reality exposure or a therapist-led treatment involving real spiders. Both groups showed improvements in fear and avoidance, with follow-up extending to a year. The authors called for further research on how the virtual approach works in everyday services. Spider-phobia trial

That is evidence about particular treatments delivered under study conditions—not proof that any spider app, online video, or one-off challenge will work. It also doesn’t promise that your treatment will take one session. Ask what evidence supports the actual service you’re considering.

Will treatment mean being surprised with a spider?

Planned exposure isn’t a prank or a test of courage. Mind describes agreeing the steps in advance, understanding the treatment, and remaining supported and able to stop. Some anxiety may be part of treatment; being kept in the dark shouldn’t be. Mind

Before committing, you could ask:

• “Would you use real spiders, virtual settings, or something else—and why?”
• “How would we agree on what happens and discuss anything I don’t feel ready for?”
• “How would we judge progress outside the appointment?”

Your own goal might be using the garden again or sleeping in your room after an encounter, rather than becoming someone who enjoys spiders. Our treatment guide explains the broader approach.

What if I’ve just seen a spider?

If you’re upset, let someone you trust know what’s happening. The NHS suggests talking about your fear and using breathing exercises to help you relax. These may help with a difficult moment, but they don’t replace treatment when the fear is taking over your routines. NHS

Keep ordinary wildlife safety in mind. You don’t need to handle a spider to prove anything.

How can I help someone who is scared?

Take their fear seriously, even if you don’t share it. Try asking, “What would help right now?” Give them time to answer.

Avoid teasing, showing them surprise spider pictures, or bringing a spider closer to “show them it’s harmless.” A frightening surprise isn’t a helpful way to offer support.

If fear is making everyday life hard, you can offer to help them look for professional support or use our appointment-preparation tool to write down what they want to say.

If repeated checking is becoming difficult for everyone at home, talk about it kindly. Don’t withdraw all help overnight to force a change; Mind warns against suddenly stopping safety behaviours on someone else’s behalf. Read our support guide for more on care and boundaries. Mind

When should I talk to someone?

If you’re missing things you enjoy, avoiding parts of your home, or spending a lot of time worrying about spiders, a doctor or therapist can help you work out what’s going on.

You could say: “My fear of spiders is affecting my day, and I’d like some help with it.” That’s a useful place to start.

Our guide to specific phobias explains the wider picture.
