spray killing spider

Spiders are a common sight in many homes, and while some people do not bother with them other people are scared to death. Many people will do anything to get rid of spiders from their homes.

Lysol, a popular disinfectant, may be one such product you’re considering to get rid of those scary eight-legged creatures. Everyone wants to know, does Lysol kill spiders? The answer is yes.

Lysol does kill spiders by clogging up the openings they use to breathe, ultimately killing them by suffocation. You need to take note that Lysol can kill a spider, but you need to spray it directly and you will need to use a lot of spray.

It will take a while for the spider to die after spraying it with half the can of Lysol.

Household Pests Affected by Lysol

Lysol is a popular disinfectant that can be used to kill a variety of household pests, including spiders.

  • Spiders: Lysol blocks their respiratory system, causing them to die.
  • Ants: Spraying Lysol on ants can kill them almost instantly.

Spiders and Natural Insecticides

While Lysol can kill spiders, you can also consider alternative, more natural methods of insect control. Many people have tried to use the natural repellent below to get rid of bugs or keep bugs away.

You can try them but there is no guarantee that they will work.

  • Eucalyptus: Eucalyptus oil is an effective spider repellent. You can mix a few drops with water and spray it around your home to keep spiders away.
  • Lemon: Lemon essential oil can also repel spiders. Mix lemon oil with water and spray it in areas where you’ve seen spider activity.

Understanding the Ingredients of Lysol

Lysol and Its Active Components

Lysol contains two primary active ingredients: benzalkonium chloride and ethanol.

Benzalkonium chloride is a powerful disinfectant that can eliminate various bacteria, fungi, and viruses. Ethanol acts as a solvent and antimicrobial agent, contributing to the overall disinfecting properties of Lysol.

These ingredients, in combination with other ingredients like sodium hypochlorite, make Lysol an effective household disinfectant for surfaces.

Spider Control Methods

Preventive Measures for Spider Infestations

Preventing spider infestations is easier than dealing with them once they’ve taken over your home.

Follow these preventive measures to keep spiders at bay:

  • Seal cracks and gaps around your home’s exterior to prevent spiders from entering.
  • Clear away clutter, especially in dark and hidden areas, where spiders like to hide.
  • Use a vacuum to remove webs and spiders when you spot them and discard the vacuum’s contents outside.
  • Regularly dust and clean surfaces to discourage web-building.
  • Keep outdoor lighting to a minimum, as it can attract insects, which in turn, can attract spiders.

Safety Precautions and Considerations

Interaction with Other Pests and Household Products

When using Lysol disinfectant spray as a spider killer, be mindful of its interaction with other pests and household products.

Lysol may not be as effective on other insects, such as mosquitoes, as it is on spiders. Ensure that you do not mix Lysol with other cleaning products, specifically bleach, as this can create toxic fumes that are harmful to both humans and pets.

Before using Lysol on furniture or your sofa, test it on a small, inconspicuous area to ensure it will not damage the material.

Safety Measures for Children and Pets

Keep safety in mind when using Lysol disinfectant spray around children and pets. Ensure that you:

  • Store Lysol and other cleaning products out of reach of children and pets.
  • Follow the recommended spraying distance on the product label for maximum effectiveness and safety.
  • Avoid spraying Lysol directly on toys, pet bedding, or other items that children and pets frequently touch.
  • Ventilate the area well after using Lysol spray to prevent inhalation of fumes.

Using Lysol Responsibly

Using Lysol responsibly is crucial for maintaining the health and safety of your household. Keep the following points in mind:

  • Always read and follow the instructions on the Lysol disinfectant spray label.
  • Avoid overuse of Lysol, as it is intended to be used as a disinfectant and not as an insecticide. For alternative spider control methods, consider using white vinegar, a natural repellent, or a designated spider killer product.
  • Do not rely solely on Lysol for disinfecting surfaces contaminated with germs and bacteria. Incorporate other disinfectant sprays or cleaning products into your cleaning routine for optimal results.
  • Remember that Lysol is not a substitute for proper household cleaning. Regularly clean surfaces and remove any food sources that may attract pests for long-term prevention.


Lysol can kill some spiders, but it might not be the most practical or environmentally friendly method. It requires a high concentration and a considerable amount of time for the substance to take effect on spiders.

Instead of relying solely on Lysol, you can explore other alternatives to deal with spider issues. Some options include:

  • Physical removal: Gently trap spiders using a glass or jar and a piece of paper, then release them outdoors.
  • Natural repellents: Use substances like peppermint oil, vinegar, or citrus peels as they can deter spiders from entering your space.
  • Chemical repellents: Look for spider-specific insecticides that can be safely used around your home.
  • Prevention methods: Keep your home clean and clutter-free, seal any cracks or crevices, and control other insect populations that may attract spiders.

Taking a more comprehensive approach to spider management will provide you with better results while minimizing harm to the environment and other living creatures.
