Does Simple Green Kill Spiders?

Spiders 2

Simple Green is a popular cleaning product in the United States, renowned for being environmentally friendly, non-toxic, and biodegradable. But many of us have wondered, does Simple Green kill spiders? In this comprehensive guide, we will delve into every aspect of this question to provide an all-in-one answer.


While some anecdotal reports suggest that Simple Green, a popular all-purpose cleaner, may kill spiders upon contact, there is no scientific evidence to support these claims. The manufacturer does not list any insecticidal properties for the product. Therefore, while it might have some effect, Simple Green is not a reliable or recommended method for spider control.

What is Simple Green?

Simple Green is an all-purpose cleaner produced by the American brand, Sunshine Makers, Inc. Its main ingredients include water, surfactant, and C9-11 alcohols ethoxylated. Previously, it contained 2-butoxyethanol, but this has been removed from the product as of 2013.

Simple Green and Spiders

Despite its primary use as a cleaner and degreaser, some users have reported that Simple Green can kill spiders upon contact. However, these are anecdotal reports and may not represent the product’s overall effectiveness against spiders. The manufacturer has not claimed any insecticidal properties for the product, and there is no scientific evidence supporting these claims.

How to Use Simple Green Against Spiders

If you choose to try Simple Green as a method of spider control, it is recommended to create a diluted solution. Mix 1 part Simple Green with 10 parts water and apply it to areas where spiders are often found, such as corners and other hiding spots. Be cautious when using the solution around plants, as it may cause damage if not properly diluted.

Potential Risks

While Simple Green is generally considered safe, there have been allegations of health problems related to its use, including blurred vision, asphyxiation, and nausea. However, these claims were made in a class-action lawsuit, and the product is not considered hazardous under the 2012 OSHA Hazard Communication Standard.

Alternatives to Simple Green

If you’re looking for a more effective method of spider control, there are several alternatives to consider:

  1. Insecticides: These are designed specifically to kill insects and are likely to be more effective than Simple Green.
  2. Natural repellents: Certain essential oils, such as peppermint and eucalyptus, have been reported to repel spiders.
  3. Other household cleaners: Some users have reported that products like Windex can kill spiders.
  4. Professional pest control: If you have a serious spider problem, it may be worth considering professional pest control services.

In conclusion, while Simple Green may kill spiders, it is not the most effective or reliable method. For better results, consider using a product specifically designed for spider control. Always remember to use any product safely and according to the manufacturer’s instructions.
