Why Do Spiders Scare You?


Did you know that about 1 in 10 people have a phobia, and about 40% of those phobias are related to insects, mice, snakes, and bats? 

There are a lot of insects all around the world. It is estimated that there are 1 million spiders per acre of land alone, and in tropical areas this number can get as high as 3 million spiders per acre of land. 

Despite spiders usually not being so deadly and dangerous, many people are afraid of them. 

Why is this, and what can we do to curve our fear of spiders?

We also have a downloadable podcast version from our podcast widget above this post. 

One hypothesis that was proposed by scientists was that people had a direct, negative experience with spiders that led to them developing this fear. 

In 1991, a man by the name of Graham Davey at City University London ran a study to see if this view was accurate. 118 undergraduate students were interviewed about their fear of spiders. 

One interesting discovery made was that females were significantly more likely to be afraid of spiders than males, and we aren’t sure why that is- subsequent studies have confirmed this. 

He discovered that many people who had a fear of spiders also had family that was afraid of spiders, but we aren't sure whether that’s genetic or environmental. 

He also discovered that people aren’t afraid of being bitten by a spider, but more so the way they generally move. Their seemingly unpredictable movements terrifies us. 

Other studies that were conducted later confirmed that some people have a genetic, seemingly innate fear of spiders. Children often report spiders as being one of the most terrifying things in their life, even if they haven’t had a direct experience of it. 

Conditioning certainly plays a factor though, as it is often in horror movies and horror literature in which bugs are depicted as giant, venomous creatures that are out to get us.


As mentioned earlier, a lot of people are afraid of the unpredictability of a spider. It could be theorized that for the unpredictable factor alone is why we are afraid of insects like spiders. 

When we can predict something, we know what will happen. We are relaxed. 

If you visualize a crazy person on the street that would scare you, the common denominator is typically erratic, irrational behavior that doesn’t follow a linear, logical path. In simple terms this means that we don’t understand what they’re about to do next, and this makes us nervous and fear for our safety. We don’t understand what the rules are, what their boundaries are, and whether they will respect our boundaries. 

The same could be said of spiders- they move in an erratic, irrational fashion. They are unpredictable like other creatures, and this scares us. When we can’t understand what their next move is, we can feel threatened on a very primal level. 

Now this genetic predictability factor isn’t all to do with the fear of spiders- when everyone else is afraid of spiders, it’s likely that you’ll develop one too. Our society is obsessed with creepy insects in movies and books, and that has no doubt added fuel to our fear of spiders. 

How do we overcome our fear of spiders? 

One possible method to overcome your fear of spiders is to simply look at photos or videos of spiders. When your brain finally makes the connection that you won’t die by observing a spider, it will begin to let you relax and you won’t be so afraid. 

If you watched the video version of this post, then you’re already one step closer to relinquishing your fear of spiders. 

Now all this being said, you should never have to deal with spiders or any pests for that matter.
