Does bleach kill spiders? – find out the facts


Dave Campbell

As soon as the weather changes from cold to warm, it’s very common to find your home has become the habitat for spiders. Conversely, as soon as the weather begins to get a little bit colder, they will seek refuge and you can end up with an infestation.

They are only dangerous if they are the poisonous variety, such as Black Widow or Brown Recluse. However, if you  or any of your family are suffering spider bites, then it is maybe time to do something about it.

So what’s the short answer? Well bleach is a common household product, used in cleaning and it can be effective for killing spiders with a spray bottle. It works quite quickly, but one drawback is that while bleach can kill spiders, it is also a corrosive chemical, and can be harmful when used around children and pets.

A readily available spider deterrent

As you try to get rid of spiders in your home, you could just be preparing a favorable condition for other creepy crawlies to invade your home. They generally hunt prey such as flies and other insects and can stop them from becoming a problem. In that case, it is necessary to deal with them yourself or to call in an exterminator if you’re afraid of spiders or suspect they pose a threat to you or your family. Bleach has also shown to be effective against maggots and other pests.

Bleach contains acetic acid and can be very effective when it comes to keeping spiders away. It also works to eliminate webs. Spraying water and bleach directly on a spider or its web is very easy and effective way of clearing them out your home. You can also use the mixture on the exterior of your home to prevent them from entering your home. It is very important to spray in all the gutters and dark crevices where the spiders are hiding.

When using this chemical, make sure to take all necessary precautions. Protective clothing and protective eye wear are highly recommended to avoid injuries as well as chemical burns from taking place when trying to remove spiders using bleach.

Today, spiders are found on every continent around the world that is permanently populated. They are also among the most diverse living things in the world with nearly 40,000 different species. However, nearly all types hate water. You may spot them hanging out in your bathroom, but you will never see them around a body of water, except for only a handful that actually live on or in water.

Although many think that spiders are insects, in reality, they are arthropods and arachnids. All spiders have eight legs and most have 4 sets of eyes. However, different types may have different eye profiles. Female spiders tend to be bigger than their male spider mates, but these creatures are very prolific. A spider may lay up to three thousand eggs in a lifetime. You may be able to identify them by their egg sacs, which look like little white balls.

Although they may be scary since some of them are poisonous, spiders also provide silk, which is the strongest material ever known by man. This material that they produce can never be manufactured even synthetically because it’s too complicated. Each and every spider produces some form of silk and uses it to make the classic web, which is used to catch its prey.

Will ordinary household bleach work?

Other everyday cleaning products you can find around your home, such as vinegar is used for spiders. Bleach is also commonly used around the home for cleaning and for laundry and is a very good solution that can be used to kill spiders.

It’s also categorized as a fungicide and a pesticide because can destroy bacteria cells. It’s also able to deter household pests such as spiders that are living in your home or outside your garden area. The acetic acid in the spray burns them on contact.

When using a chlorine product or solution, extra precautions should always be taken because it has quite harmful side effects on both humans and can burn into inorganic surfaces.   Always make sure you protect your eyes and hands when using water in a spray with bleach around all the affected areas.

To eliminate them, you need the following materials:

How to make an effective spray:

To prepare bleach to kill spiders, first mix three parts of water with one part of bleach (you can use Clorox or some other brand). As soon as you have thoroughly mixed them, pour the solution into a spray bottle. Spray the mixture directly on the spiders or the affected area where you find their webs, within a six to ten inch distance, using a spraying bottle filled with the mixture.

Use a spray to treat all the affected areas. The amount of solution you need depends on the size and number of spiders you want to get rid of. The bleach solution should be sprayed on the places that they are known to hide, nest or enter the home once a week until the winter season comes to act as repellant. As soon as all the spiders are dead, you should sweep the whole area to remove them and dump them into the trash can. Any remaining solution that can be seen on the surface should be wiped off thoroughly so as to prevent bleaching effects that may take place.

Once again, watch how close you are when using the mixture and don’t inhale the chlorine fumes. This is because it is harmful and can damage your skin and eyes if it comes into contact with these organs for a longer period of time or in larger quantities. Another way to repel them from a particular area is to let a teabag soak in the solution for a few minutes, and place one or more of them in the problem areas around the house. Always be careful of the areas you spray since it can discolor floors and walls.
