That claim is almost certainly exaggerated or outright misleading.
Phrases like “rats and roaches disappear in just one day” are typical of pest-control marketing or social media ads, and real-world pest control doesn’t work that instantly in most cases.
What actually happens with rats and cockroaches
- Rats: Effective control usually takes days to weeks, depending on infestation size and whether entry points are sealed.
- Cockroaches: You may see a reduction within 24–72 hours after treatment, but complete elimination often takes multiple treatments.
Why “one day” claims are unreliable
Even strong treatments (professional baits, gels, or fumigation):
- Don’t reach every hiding spot immediately
- Often rely on pests carrying poison back to nests
- Require follow-up to kill eggs and remaining survivors
So even the best methods don’t guarantee instant disappearance.
What actually works
For rats:
- Sealing holes and entry points
- Snap traps or professional bait stations
- Removing food and water sources
For cockroaches:
- Gel baits (very effective)
- Insect growth regulators (stop reproduction)
- Deep cleaning + removing moisture sources
Red flag signs in these ads
- “100% guaranteed in 24 hours”
- “No need for professionals”
- “One-time use solves everything forever”
Those are classic oversimplifications.
