Mice and rats can be persistent unwanted houseguests, but a simple household trick may keep them from coming back without relying on chemical repellents, according to Polish outlet InfoWET.pl.
The publication said mice and rats most often choose attics, basements, garages or pantries as hiding spots, favouring quiet areas that people rarely enter.
Why the smell of cats works
Rodents have a highly developed sense of smell and instinctively avoid places they perceive as dangerous, the outlet noted. That is why mice and rats steer clear of areas where they can detect the scent of a cat.
InfoWET.pl recommended using used litter from a cat's litter box as a simple deterrent. The used litter should be poured into cloth pouches or old socks, then placed in spots where signs of rodents have been seen.
Keeping the method working
For the trick to stay effective over time, the pouches of litter need to be replaced regularly, since the smell fades and loses its deterrent power. The outlet added that litter alone will not be enough if a building still has accessible food or easy entry points for rodents.
InfoWET.pl also advised limiting access to food and carefully protecting food supplies, sealing any holes, gaps and cracks rodents could use to get inside a building, and regularly cleaning areas where crumbs or food scraps might collect.
If an infestation is too large, the outlet said, the litter method may not be enough on its own. In that case, it recommended using traps, specialised products, or calling in a professional pest control company.
Why autumn draws mice indoors
The outlet also referenced earlier reporting by Realsimple explaining why homes become more attractive to mice in autumn. As the first autumn cold sets in, rodents begin actively searching for a warm, safe place to shelter for the winter.
Pest control experts cited by Realsimple said mice are drawn in particular by gaps and other easy entry points, warm and cosy spots, and exposed food or crumbs.
