Does salt get rid of spiders?

Salt mixed with water as a form of salt solution will get rid of spiders. Salt acts as an effective spider repellent but will not cause the spider to perish immediately. The salt solution can efficiently get rid of spiders if applied to a spider or on their nest and stop further infestation.

Salt is a spider’s natural enemy and works as a very good repellent. When a spider-infested area is sprayed on with salt solution, it can successfully deter spiders from further infestation.

Since salt is a safe and natural item, it can be applied on spider nests, spider egg sacs, and potential infestation sites to get rid of spiders.

Salt is poisonous to spiders and excellent for pest control. However, whether a spider perishes on applying the salt solution depends on the concentration of salt to water ratio.

But even if the concentration is low, the salt solution is effective in repelling the spider and eventually causes it to perish.

Besides spraying salt solutions, another viable option is to place small salt deposits in corners and holes around the house where spiders can potentially enter. These salt deposits will work similar to salt solution sprays and repel spiders for longer periods.

What does salt do to spiders?

Exposure and contact with salt cause spiders to perish sooner or later. Salt is a spider repellent and is often used in DIY homemade pesticides for spiders. Applying salt solution in spider nests will destroy it and cause the spiders to either escape or perish on the spot.

What naturally deter spiders?

There are several items found in nature that work as an effective spider repellent. Some of those items have been listed below:


Mixing an ounce of salt in a gallon of warm water to make a salt solution and spraying on a spider will get rid of it. You can consequently spray it on spider nests or on areas with a spider infestation.


Crush fresh chestnuts into tiny chunks or powder and deposit them in common entry zones for spiders. They are best for keeping an area spider free and not for immediately dealing with a spider.


Fill half a bottle with white vinegar and the other half with warm water, you might want to add a teaspoon of coconut oil for better potency. Afterward, spray the solution on spiders or their nests to ward them off.

Peppermint oil:

Spiders dislikes the strong scent of peppermint oil, thus making them ideal spider repellent while being a home fragrance as a bonus.

You can prepare a peppermint oil solution by putting 15 teaspoons of the oil along with half a teaspoon of dish soap in a bottle of water and spray.

Diatomaceous Earth:

DE would be a great solution if you don’t want to harm other plants or organisms nearby. DE doesn’t repel spiders but is effective at getting rid of them once exposed. Spread a thin layer of DE over an infested area and it’ll take care of the spiders once they’re in contact.

How to get rid of spiders?

Getting rid of those pesky little bugs might seem challenging to some but it’s quite easy if you follow the steps below:

Declutter The House:

Spiders are most commonly found in corners and spaces with the least human activity. Therefore, try to move your furniture around and unused items lying around the basement, garage, and attic.

Applying Repellents:

Once the secluded spots have been exposed, use a pump sprayer to apply the repellent. You can either choose to use the homemade repellent solutions mentioned above or use chemical pesticides such as Reclaim I/T for a stronger impact.

If you are using chemical pesticides, you should spray for 3-4 seconds around window corners, doors, under patio coverings along eaves, and in the basement and garage corners.

For natural homemade repellent, spray a generous amount of either salt solution, vinegar, or peppermint oil. You can ideally place ground chestnuts or salts on locations where you find spiders lurking.

Trapping Residue Spiders:

After you get rid of some spiders and their nests, some might still be lurking around that are hard to track down. To deal with them, you can get glue boards found at your local stores and place them in places with high spider activity.

Clean-up and Prevention:

If you have completed the previous steps properly, you have stopped the spiders at their source, however, you should clean their remains and prepare for the arrival of new spiders. To do so, use a broom to clean up cobwebs around the corners or under patio coverings.

Next, spray the remaining pesticide at the perimeter of your house with the directions: 3 feet high on your house and 3 feet outwards. Additionally, use caulks to seal off any cracks that might be potential entry points for spiders and bugs.

How do you know if you have a spider infestation?

Signs of spider infestations are very visible and easily identifiable when looking at the right spots. If you find the signs below in your garage, attic, or basement, your house has a spider infestation.

Visible spiders around the house:

One or two spiders around the house are quite normal but if you spot more than that on a usual basis, you might have an infestation.

They might not be visible in an active spot around you but if you inspect the corners around the house and spot spiders more than usual then it’s time to take measures.

Spider egg sacs:

Spider webs are a common sight in corners around the house, but if the webs are fresh and contain egg sacs, then it’s a sign of recent spider activity and the spiders are crawling about somewhere inside your house.

Spider eggs should urgently be dealt with since a spider egg sac contains over a hundred hatchlings and there could be multiple egg sacs throughout the house.

Insects trapped in webs:

Small insects and bugs are the main food source of a spider and they capture these insects using their webs. They aren’t too picky about their diet so you can expect to see insects ranging from ants, moths, flies to even mosquitoes tangled in their webs.

Spiders usually trap insects in their webs and save them to eat later, so if you notice an increasing amount of bugs trapped in spider webs, then it’s a sign of recent spider activity. Insects attract spiders, so close windows and doors to prevent insect entry.

How do I get rid of giant spiders in my house?

Among the swarms of tiny house spiders, sometimes giant spiders could also find their way to your home – this usually happens in September when it’s the mating season of spiders.

To discourage their entry, you should clean the trash can where you throw away leftover food to keep other insects away.

Keep your house clean and dust up any corners that might be a potential nesting spot for spiders. You can also keep plants like Peppermint or Eucalyptus that keep away spiders.

However, if it’s already too late and there is a giant spider lurking about – you can use a vacuum to remove the spider safely. You can also contact pest control if the spider is a black widow or a brown recluse since they are venomous.

Does salt attract spiders?

Salt is poisonous to spiders and doesn’t attract them, instead of salt is good at repelling them. But indirectly, salt could result in the entrance of spiders because salts attract other insects like ants.

Spiders feed on other small insects, so an increase of insects in your house means more food for spiders.

Other important factors that attract spiders indoors – warmth, leftover food, and houseplants – are among the common. Spiders look for warm and humid places to nest and mate and houseplants are the most common spots that provide warmth, humidity, and shelter.

Does coconut oil repel spiders?

Coconut oils do play an essential part in repelling spiders by being a key component of a spider repellent solution. Although the standalone effect of coconut oil on spiders is unknown, they are often mixed with white vinegar to form solutions that act as a natural spider repellent.

Final Thoughts

Salt solutions formed from salt and water mixture act as an effective spider repellent and will get rid of spiders – but don’t finish it off immediately. Salt solution efficiently prevents further spider infestation if applied onto a spider or their nest.
