Spider Killer Buyer’s Guide

Before venturing out to buy a spider killer, we have to look into their types and features. Spider killers are mainly of five types- aerosol, natural repellents, sprays, traps, and dust. After you learn about their different types, you will know the one that best suits your needs.


The aerosol provides great coverage, and the process of application is both easy and quick. You can spray it directly on spiders in places where they hide. It helps to spray the foundation of your home in a little time. But it is also important to maintain a distance of 12 inches between the surface and the nozzle. Aerosols do have their disadvantages; they are more expensive, and you will need some cans to spray the whole foundation. Few of them are oil-based that leaves behind a greasy residue.

Natural Repellents

Natural Repellents do not use chemicals or harmful ingredients to drive away spiders. They use compounds and plants that repel the spider.

Peppermint oil is one of the best natural repellents. We just have to take some drops of water and mix it with the peppermint oil. We can then spray it around the crevices, corners, and cracks around our homes. It will help you get rid of spiders in your home and leave behind a fresh minty scent.

We can also use white vinegar to keep away spiders. All we have to do is mix lemon, vinegar, and water. This mixture will keep your home clean and spider free.


There are different kinds of sprays available for killing spiders. They are liquid spray bottles, nozzle sprays, big jugs, and aerosol cans. Sprays consist of chemicals that are synthetic and attack the nervous system of the spider. It causes a fast death.

You can use it outside of your home so that it forms a barrier and keeps out spiders. Spot treatments can also be done using sprays.

Spray bottles have lightweight and can be reused. You only require a pesticide that is soluble in water to use them. But, it causes hand fatigue while spraying big areas, which is its disadvantage. You must also keep them out of reach of pets and children.


Traps contain sticky surfaces. They can, therefore, catch spiders with ease and hold them till death. You can place them on baseboards and walls where spiders are usually seen.

Some of them fold up to keep away pets and children from touching its surface. It is also easier to remove the dead spiders with traps.


Some dust cut and scrape the spider’s body and dehydrates it over 24 to 48 hours. The spider then dies. Other types of dust contain silica or diatomaceous earth that work in the same way and leave it to die. Silica dust sometimes has pyrethroid for knocking down spiders.

Dust can blow away with the wind, so you must be careful while using it around pets and children.


As some spiders pose a threat to our family’s safety, we should go out to buy some spider killers. In our article, we have covered the top 10 spider killers available in the market. You can make your choice from the top 3 – Best Overall, Premium, and Best Budget. The best overall Ortho 0220910 Insect Killer gives 12 months of protection.
