That sounds like one of those “miracle fixes” claims—but in real life, rats and cockroaches don’t reliably disappear in a single day from any simple home remedy.
Pests like these usually require a combination of:
- removing food and water sources (cleaning, sealing containers)
- blocking entry points (cracks, drains, holes)
- traps or bait stations for rodents
- gel baits or professional-grade insecticides for roaches
- sometimes professional pest control for heavy infestations
Some mixtures you see online (like baking soda, onions, essential oils, etc.) might repel a few insects temporarily, but they don’t eliminate an established infestation in 24 hours.
If you tell me what you were referring to (the “this” in your message), I can break down whether it actually works or not—and what would work better in your situation.
