That sounds like one of those viral “miracle fixes,” but nothing reliably makes rats and cockroaches disappear completely in just one day in real-world conditions.
If someone is claiming that, it’s usually either:
- an exaggerated marketing trick,
- a strong chemical treatment that still requires follow-up, or
- something unsafe or not approved for home use.
In practice, getting rid of rats and cockroaches takes a combination of steps:
- Cut off food and water sources (sealed containers, clean crumbs, fix leaks)
- Block entry points (cracks, drains, holes in walls)
- Use targeted bait or traps (more effective than random sprays)
- Maintain repeated control efforts over days or weeks
Professional pest control can reduce infestations quickly, but even then, complete elimination usually isn’t instant.
If you want, tell me what problem you’re dealing with (rats, roaches, or both, and where in the house), and I can suggest a more specific and effective plan.
