Will Bleach Kill Spiders?

By Staff WriterLast Updated April 05, 2020

Pure bleach will kill spiders if it is applied directly to the insects. The easiest way to use bleach is to mix it with water in a spray bottle.

Bleach also works to remove spider webs. Spraying bleach and water directly on spider webs is an easy and effective way to remove them from a home. The bleach mixture can also be used on the exterior of the home to eliminate spiders that may enter the house. It is important to spray around gutters and other dark crevices as these are where the majority of spiders hide. Users should also take safety precautions when working with bleach. Gloves and protective eyewear are recommended to prevent both injuries and chemical burns from occurring.
