How to Use Vinegar to Kill Spiders

Vinegar can be an effective and natural solution to repel and kill spiders. The strong smell of vinegar is known to deter spiders, and when sprayed directly on them, it can be lethal.

Here’s a detailed explanation of how to use vinegar to deal with spiders


  1. Distilled white vinegar
  2. Water
  3. Spray bottle


Prepare a Vinegar Solution

Mix equal parts of distilled white vinegar and water in a spray bottle. For example, if you have a 16 oz (473 ml) spray bottle, mix 8 oz (237 ml) of vinegar with 8 oz (237 ml) of water. You can adjust the quantities based on the size of your spray bottle.

Identify Spider-Infested Areas 

Determine the areas where you frequently spot spiders or webs. Common areas include corners, windowsills, door frames, and dark spaces such as basements or attics.

Vacuum and Clean

Before using the vinegar solution, vacuum any visible spider webs or spiders to physically remove them. Also, clean the area thoroughly to eliminate any spider eggs or debris that might attract spiders.

Spray the Vinegar Solution

Shake the spray bottle containing the vinegar solution to ensure it’s well-mixed. Then, spray the solution directly onto spiders or onto areas where spiders are likely to build their webs or hide. Focus on cracks, crevices, corners, and other potential entry points.

Repeat the Process

For better results, repeat the spraying process every few days, especially in spider-prone areas. This helps maintain a strong scent that repels spiders and prevents them from returning.

Additional Tips For Using Vinegar

Test In Inconspicuous Areas

Test vinegar on inconspicuous areas first to prevent damage. Apply a small amount on delicate surfaces or materials and check for any adverse effects like discoloration before using it more extensively.

Use Caution Around Plants

Take caution when using vinegar around plants as it can harm or kill certain species. Ensure you avoid spraying vinegar directly on plants or near sensitive vegetation to prevent any potential damage.

Combine With Other Spider Deterrents

To enhance the effectiveness, you can combine vinegar with other natural spider deterrents, such as essential oils (e.g., peppermint, tea tree, or citrus oils). Add a few drops of the chosen essential oil to the vinegar solution and mix well before spraying.

Maintain Cleanliness

Spiders are often attracted to clutter and unclean areas. Regularly clean your living spaces, eliminate clutter, and keep your surroundings tidy to discourage spiders from taking up residence.

Remember, while vinegar can be useful in repelling and killing spiders, it may not eliminate an infestation entirely. If you have a severe spider problem or concerns about venomous spiders, it’s advisable to contact a professional pest control service for assistance.

Frequently Asked Questions

Can vinegar kill all types of spiders? 

Vinegar can kill most of the common house spiders because it contains acetic acid which is harmful to them. 

However, some species of spiders are resistant to acetic acid, so vinegar might not work effectively against them. 

It’s important to identify the type of spider before using vinegar as a solution.

Does vinegar work better than insecticides to kill spiders?

Vinegar can be as effective as insecticides in killing spiders, but it may take longer and require multiple applications. 

Insecticides contain synthetic chemicals that are specifically designed to kill insects, while vinegar is a natural solution that may be safer for pets and children. 

However, using a combination of both vinegar and insecticides can provide the best results in eliminating spider infestations.

How much vinegar should be used to kill spiders?

To use vinegar to kill spiders, you can mix equal parts of water and white vinegar in a spray bottle. 

This solution is strong enough to repel and kill spiders upon contact. 

It’s important to shake the mixture thoroughly to ensure it is well-mixed before using it. 

You can then spray the solution directly on spiders, webs, or areas where spiders are commonly found, like corners, closets, and cabinets.

Will vinegar harm other household pets if sprayed around the house?

Vinegar is generally safe for pets and humans, but it can cause mild irritation if it comes in contact with the eyes or skin. 

However, if your pets have any respiratory issues, spraying vinegar around the house can exacerbate their symptoms. 

It’s best to keep your pets away from the area that you’ve sprayed with vinegar until it dries completely. 

Additionally, if your pet ingests vinegar, it may cause nausea, vomiting, or diarrhea. 

While vinegar is a safe and natural solution, it’s always recommended to consult with a veterinarian before using it around pets.
