Does bleach on walls kill roaches?

Bleach can kill roaches on contact due to its strong chemical properties, but it is not an effective long-term solution for roach infestations. Roaches can often survive in hidden areas and may return once the bleach has dried. Additionally, using bleach can pose health risks to humans and pets, and it doesn't address the root cause of the infestation. For effective roach control, it's better to use targeted insecticides or professional pest control methods.
