Do Cats Kill Spiders: Unraveling the Mystery

Cats naturally have predatory behaviour. But do cats kill spiders? Yes, cats do kill spiders. While some people believe that this is because they are natural predators, others believe that it is simply because they are curious creatures who like to play with small insects. However, there is no scientific evidence to support either of these theories.

Sure, cats may kill spiders on occasion – but does that mean they’re doing us all a favor? Probably not. Some experts believe that cats may be more harmful to spider populations than helpful.

Here’s the thing: when a cat catches a spider, it usually doesn’t eat it. So the spider simply becomes another casualty in the never-ending war between these two species. And as we all know, nature is all about balance.

Will Cats Keep Spiders Away?

There is no scientific evidence to support the claim that cats keep spiders away. However, some people believe that because cats are natural predators of small animals such as rodents and insects, they may also help to deter spiders. Additionally, cats typically spend a lot of time grooming themselves, which could remove any spider webs or eggs that might be present on their fur.

How Do Cats Feel About Spiders?

There’s no denying that cats and spiders have a bit of an uneasy relationship. While our feline friends may not be outright afraid of these eight-legged creatures, they certainly don’t seem to enjoy their company very much. So what is it about spiders that sets cats on edge?

For starters, it could be the way they move. Spiders are quick and agile, darting around in ways that can startle even the most stoic of cats. And then there’s the fact that many spiders are venomous – something that instinct tells cats to avoid at all costs.

Of course, not all spiders pose a threat to cats (or humans, for that matter). But even harmless varieties can elicit a strong reaction from our furry companions. In the end, it seems like most cats would simply prefer to steer clear of spiders altogether!

Are Spiders Scared of Cats?

It’s difficult to definitively say whether spiders are “scared” of cats in the same way a human might be. Spiders lack the complex emotional range and cognitive abilities we possess. However, we can consider some factors:

Predatory instincts: Cats are natural predators with keen senses that make them well-suited to hunting small creatures like spiders. This inherent threat could cause spiders to react defensively when encountering a cat.

Vibrations and movement: Spiders are sensitive to vibrations and movement, which are prominent features of a cat’s approach. This heightened awareness might trigger an escape response in the spider.

Chemical cues: While not definitively proven, some research suggests spiders may detect chemical signals from predators, including cats. This could further contribute to a defensive reaction.

However, it’s important to remember:

  • Individual variation: Spider behavior can vary greatly depending on the species, situation, and individual. Some spiders might be more bold or curious, while others might be more cautious or easily startled.
  • Limited understanding: We still have much to learn about spider behavior and their perception of the world around them. Attributing emotions like fear to them remains speculative.

Therefore, while spiders might exhibit defensive behaviors in response to cats due to their predatory nature and sensory cues, it’s not accurate to say they are “scared” in the same way humans experience fear.

Are Cats Safe from Spiders?

Most people believe that spiders are attracted to cats because of their warm bodies and lack of fur. However, there is no evidence to support this claim. Many experts believe that spiders are more afraid of cats than anything else.

This is because spiders are natural predators of insects, and cats are natural predators of spiders. So when a spider sees a cat, it is more likely to be scared off than to try to attack it.

Do Cats Kill Spiders in the House

If you have a spider problem in your home, you may be wondering if cats can help solve the issue. After all, cats are known for their hunting abilities, so it stands to reason that they could take care of a few spiders. Unfortunately, the answer is not as simple as you might hope.

While it is true that some cats will kill spiders, there is no guarantee that your cat will be one of them. Some cats simply aren’t interested in hunting spiders, while others may even be afraid of them. So if you’re looking to your cat to help with your spider problem, you may be out of luck.

Of course, that doesn’t mean you can’t appreciate your cat’s efforts if they do happen to catch and kill a spider in your home. Just don’t count on them to completely rid your house of these creepy-crawly pests!

Do Cats Kill Spiders Reddit?

Based on discussions on Reddit, there seems to be a consensus that cats frequently encounter and interact with spiders, but their behavior towards them can vary:

Yes, cats often kill spiders:

  • Many users share anecdotes of their cats hunting and killing spiders.
  • The natural predatory instincts of cats make them drawn to small, moving creatures like spiders.
  • Some users even joke about their cats being their personal “spider patrol.”

However, not all cats kill spiders:

  • Some users report their cats simply playing with spiders or showing little interest in them.
  • Individual cat personalities and experiences can influence their behavior towards spiders.
  • Fearful or cautious cats might avoid spiders altogether.

Additionally, some points of caution are raised:

  • Venomous spiders: While most house spiders are harmless, some Redditors express concern about the potential danger of venomous spiders to cats.
  • Playing with prey: The hunting instinct can lead to cats playing with spiders before killing them, increasing the risk of getting bitten.
  • Accidental ingestion: Some users worry about their cats accidentally ingesting spiders, which could be harmful depending on the spider species.

Overall, Reddit suggests that while many cats do kill spiders, their behavior can vary based on individual personality and the specific situation. It’s important to be aware of potential risks from venomous spiders and supervise your cat’s interactions with any small creatures.

How to Get Rid Of Spiders?

There are several approaches to dealing with spiders in your home, ranging from natural repellents to professional pest control. Here are some options to consider:


  • Seal entry points: Inspect your home for cracks, gaps, and holes around windows, doors, pipes, and utility lines. Seal these openings with caulk or weather stripping to prevent spiders from entering.
  • Reduce clutter: Remove clutter from corners, baseboards, and behind furniture where spiders like to build webs. This eliminates hiding spots and reduces potential prey (insects) that attract spiders.
  • Maintain a clean environment: Regularly vacuum and sweep floors, paying attention to corners and edges. This removes spiderwebs and discourages them from establishing themselves.
  • Store food properly: Seal food containers tightly and avoid leaving crumbs or spills on surfaces. This reduces the availability of food sources for insects, which in turn attract spiders.

Natural Repellents:

  • Peppermint oil: Spiders dislike the smell of peppermint. Mix 10-15 drops of peppermint essential oil with water in a spray bottle and spritz around entry points, corners, and potential hiding spots.
  • Vinegar: White vinegar also deters spiders. Mix equal parts white vinegar and water in a spray bottle and use it similarly to the peppermint oil solution.
  • Cedarwood: The scent of cedarwood repels spiders. Place cedar chips or sachets in attics, basements, and other areas where spiders frequent.

Other methods:

  • Diatomaceous earth: This powder dehydrates insects and spiders. Apply a thin layer around entry points and potential hiding spots, following safety instructions carefully.
  • Sticky traps: Place commercially available sticky traps in strategic locations to catch spiders.
  • Vacuuming: Simply vacuuming up spiders is a quick and effective way to remove them.

Professional pest control:

If the spider problem persists or you have concerns about venomous species, consider contacting a professional pest control service. They can assess the situation and recommend the most effective treatment plan.

Important considerations:

  • Identify the spider: If you’re unsure about the type of spider, it’s best to avoid direct contact and seek identification from professional or reliable online resources.
  • Safety first: When using any repellent or insecticide, always follow the product instructions carefully and prioritize safety measures like wearing gloves and proper ventilation.
  • Humane approach: If possible, opt for humane methods of spider removal, such as capturing and releasing them outdoors instead of killing them.

Remember, the best approach often involves a combination of prevention, natural repellents, and targeted removal methods depending on the severity of the situation.


The answer to this question may surprise you – cats do not kill spiders because they are predators. Instead, cats kill spiders because they are curious and playful creatures that enjoy stalking and playing with small prey. While a cat’s predatory instinct might lead it to kill a spider on occasion, typically, cats will leave spiders alone.
