There are several ways to kill roaches overnight, according to the search results:
- Baking soda: Mixing sugar with baking soda will lure the roaches to eat, and the baking soda will cause their stomachs to swell and eventually explode.
- Bleach: Spraying cockroaches with bleach or an ammonia mixture will poison them, but be cautious with this powerful chemical.
- Borax: Borax is a powdery substance that dehydrates the cockroaches exoskeletons and kills them.
- Boric acid: Boric acid dehydrates the exoskeleton until the roaches die.
- Insecticidal sprays: These are a great way to both kill roaches and repel them.
- Roach traps: Baited roach traps work by either trapping the roaches inside or luring them to eat poison.
It's important to note that while these methods can be helpful when you see one or two roaches, they won't necessarily solve a larger infestation.
