rats is certainly attention-grabbing, but it shouldn’t be presented as a guaranteed solution.

Seal the openings. Remove food sources. Eliminate hiding places. Use appropriate traps. Clean rodent contamination safely.
These measures target the actual reasons rodents remain in a home and are consistent with public-health guidance from the CDC.
So before reaching for a homemade mixture, take a few minutes to inspect your home.
The most effective “rat remedy” may be the hole in the wall you’ve never noticed.
