If you have arachnophobia, you may be genuinely terrified. Spotting a spider indoors can be distressing, especially if you're too scared to get close. The best solution in such a situation is to use an effective cleaning and disinfecting product that can also kill spiders, and Lysol can prove to be an effective solution.
Although it is one of the most effective spider-killing solutions, safety measures must be taken into consideration. So, this blog discusses how Lysol helps eliminate spiders, its alternatives, and some good-to-know safety measures.
How Does Lysol Kill Spiders?
Spiders breathe through small openings in their exoskeleton called spiracles. When Lysol is sprayed over the spiders, the chemical ingredients can coat the passage in the exoskeleton, which can gradually suffocate them to death. However, the process isn't quick and easy, as it takes around a few hours for the spider to die.
While Lysol can be effective if no other solution is available, it requires a large amount, sometimes up to half a can, to eliminate a single spider. Spray the Lysol directly onto the spider, but remember - some species may jump. After you've sprayed them with Lysol, the spider may either remain in one place or scurry off, but it will eventually die from the chemical exposure.
Also, always use Lysol in a well-ventilated space and ensure pets are removed from the area. This is because aerosol disinfectants can be harmful when inhaled or ingested.
What Are the Ingredients in Lysol?
The two primary active ingredients, benzalkonium chloride, and ethanol, contribute to Lysol's effectiveness. Benzalkonium chloride is a strong disinfectant that can kill a wide range of bacteria, fungi, and viruses.
Whereas ethanol serves as a solvent and an antimicrobial agent, which enhances the germ-fighting ability of lysol. When combined with sodium hypochlorite, these ingredients make Lysol a perfect disinfecting solution for household surfaces.
Things You Must Know About Using Lysol for Killing Spiders
Here are certain things that are important to know when using Lysol to eliminate spiders -
-
You'll need approximately ¼ of a full can of Lysol disinfectant spray to kill a spider.

What Are Other Alternatives to Lysol?
Lysol can definitely kill spiders, but you can also consider other alternatives that work as a great spider repellent, such as -
Eucalyptus

Eucalyptus essential oil is one of the best spider repellents. You can make a spray by mixing a few drops of oil with water and spraying it in your home. It'll keep the spiders away.
Lemon

Consider using lemon essential oil as an alternative to Lysol. They are easy to use and can repel spiders easily. Create a spray by mixing lemon oil with water and apply it to areas where you frequently see spiders dwelling.
What Are the Safety Precautions for Using Lysol?
Though Lysol is an effective disinfectant and gets rid of spiders, there are some safety precautions you must follow -
Interactions With Other Pests and Household Items
When using Lysol, it must be noted that you must be cautious about its effect on other pests and cleaning products. It is generally ineffective against bugs like mosquitoes. Also, ensure not to mix Lysol with other cleaners, such as bleach, as this can emit strong and dangerous fumes that can harm both people and pets living in the home. It is also advisable to test Lysol in hidden spaces to ensure it doesn't cause damage to the furniture.
Children and Pets
If you have children and pets at home, here are some safety measures you need to follow -
-
Keep Lysol and other cleaning products in a place where children and pets cannot access them.
-
Follow the spray distance guidelines on the label to ensure safe and effective use.
-
Never spray Lysol on toys, pet bedding, or surfaces where little hands or paws frequently touch.
-
Ensure proper ventilation after spraying Lysol throughout the room.
Ensure to Use Responsibly
It is advisable to always read the instructions on the packaging before using it. Also, remember, Lysol is a disinfectant, not a pest, so don't use it excessively to kill spiders. You can also opt for vinegar, which is a natural deterrent. Additionally, keep the surface clean and get rid of all the food crumbs left that might attract pests.
