Will caustic soda kill ants

Yes, caustic soda (sodium hydroxide) can kill ants due to its highly corrosive nature. When ants come into contact with it, the chemical can damage their exoskeleton and internal tissues, leading to death. However, using caustic soda for pest control is dangerous and not recommended, as it can harm humans, pets, and the environment. Safer and more effective pest control methods should be considered.
