How do you kill roaches with bleach?

To kill roaches with bleach, mix a solution of one part bleach to ten parts water. Spray this mixture directly onto the roaches, as the bleach can damage their exoskeleton and respiratory system. However, it's important to use bleach in a well-ventilated area and avoid mixing it with other cleaning products, especially ammonia, to prevent toxic fumes. Keep in mind that while bleach may kill roaches on contact, it does not eliminate their eggs or prevent future infestations.
