White vinegar is better regarded as a repellent of spiders. Spiders hate the scent of white vinegar or the acetic acid located within. Spiders should be repelled to the point of staying far away from any area with this scent.

The diluted solution you make with white vinegar will harm, kill or repel spiders, but the best part is that your children, animals or anyone in your household are completely safe.

The solution you have chosen today is mixing safe and non-toxic vinegar with equal parts water in a spray bottle. Now, you see a spider and decide to spray it directly. Will vinegar spray kill a spider right away?

With equal parts vinegar and water, the acetic acid content which serves as a natural insecticide will not instantly kill the spider. You can try to one of two methods if you want the spiders to die instantly:

  • Increase the amount of vinegar and add less water in the spray bottle.
  • Spray vigilantly. 
  • Spray the 50/50 diluted solution to stun the spider, then stomp on it. 

If you don’t wish to be actively killing spiders, simply spray and rest assured that the scent and acetic acid content in your solution will deter and repel spiders from coming back to this area.

How Does Vinegar Get Rid of Spiders?

Do you like the smell of vinegar? Well, spiders absolutely detest it. They would rather be anywhere else instead.

You sprayed vinegar with equal parts water and now the spider smells it. If contact is made, the sour taste and acetic acid will create a triple action knockout blow.

  • Scent
  • Taste
  • Contact

This all it takes for a spider to try an evade the area before the acetic acid in vinegar harms or kills it first. If you also dislike the scent of vinegar, it may also repel you from wishing to be in this space.

Squeeze orange slices into this spray bottle to improve the odor while increasing the amount of acetic acid at the same time.

Does Vinegar Repel Spiders?

Yes. The next time you think to step out to buy insect repellent or insecticide to deal with a spider infestation, check your pantry first for some vinegar.

Spiders are more sensitive to the scent of vinegar than many other critters and pests. They also taste it in the air after you have sprayed the mist all over the areas where you witnessed or suspected the infestation.

All it takes is a 50/50 diluted mix of vinegar with equal parts water and you’ve got yourself a great, cheap, easy and effective spider repellent.

How Quickly Does Vinegar Kill Spiders?

How much vinegar are you using? Popular advice suggests that equal parts vinegar and water in your spray bottle is all takes to repel spiders.

Are you looking to kill spiders right away? Add more vinegar to increase the acetic acid content and the spiders will die faster.

A diluted bottle with vinegar and water in equal parts will kill a spider in about 20-30 minutes after making contact without you directly spraying at it.

They may crawl over the solution, taste, touch and smell it, then slowly begin to die. A direct hit of spray or drowning them with constant pumps from the bottle will kill a spider right away.

How Long Does Vinegar Keep Spiders Away?

Your spider problem will hopefully be solved with routine vinegar and water spraying action 2-3 times a month. You can start by attacking the infestation head on to kill, repel and reduce the problem.

A few survivors may return, but the scent and the acetic acid content of vinegar will most likely keep them away.

You can also fill 2-3 bowls with vinegar, water and even add orange slices to help improve the odor for you while boosting the acetic acid.

Spiders will keep away from areas where these bowls are located. Use this bowl strategy for 2-3 days and spiders in this area should be a thing of the past.

How to Use Vinegar to Kill Spiders

The first thing you have to do is to mix equal parts of white vinegar and water. Prepare a mixture, fill it in a spray bottle and shake well.

Now, spray this mixture directly on the spiders, and on their webs.

As told earlier, white vinegar can also be used for repelling spiders. So you can also use it that way.

Spray the mixture on dark corners, and near the entry points of your house like doors, windows etc.

You can also place small dishes of vinegar in some areas of your house. Its odor alone will repel them.

Can I Get Rid of Spiders with Vinegar Alone?

You can use white vinegar to kill a few spiders if you use it correctly.

But to get rid of all the spiders from your house, vinegar is not a good choice for you.

You can repel a few spiders, but it’s not highly effective on which you can trust.

I’ll say that, if you use the vinegar remedy at your home, then there are equal chances that it’ll work or don’t work.

But, if you have vinegar at your home, then try it. You’re not spending any money. If it works, then there is nothing better than this.

But if doesn’t, then you can use professional products like sprays, bug bombs etc. If you want to check, I wrote an article about Spider Foggers a few days ago.

Final Words

White vinegar remedy can work for you, so I highly recommend that, if you have this at your home, try it at least once.

You can also use hair spray to kill spiders, I wrote an article on that topic here.
