Rats are deemed to be unwelcome visitors to most homes. These pests not only can carry diseases and create health risks, but they're also incredibly destructive, chewing through walls, insulation, and electrical wiring. Once a rat problem has been discovered, it is imperative to act quickly to remove the rats and ensure they do not return.

To naturally deter rats, experts at BugWise Pest Control recommend targeting their sense of smell. Rats have an incredibly sensitive sense of smell and use it wisely throughout their life. Rats have such a good sense of smell that they'll be able to detect the presence of food inside your home, even if they're still outside.

One particular scent that "stands out as a particularly powerful deterrent" is peppermint, according to the rodent experts.

They added: "Its robust and minty aroma is something rats find repulsive, making it an excellent choice for your DIY rat repellents.

"When you're crafting homemade solutions to protect your home, adding a few drops of peppermint oil to cotton balls and placing them in areas where rats frequent can create an invisible barrier that keeps these pests away."

Experts at Pest & Pollinator also recommend using peppermint oil and even shared how a customer dealing with rats was successful when using this natural deterrent.

They said: "Peppermint oil has a strong botanical scent that rats dislike. One customer successfully repelled a rat by stuffing a peppermint oil-soaked tissue into the rat hole chewed into the wall. The rat appeared to never come back."

BugWise Pest Control also recommend using spicy scents to "repel rats". They said, "Cayenne and red pepper flakes offer a fiery solution that rats detest.

"These spicy scents act as a natural barrier, creating an inhospitable environment for unwelcome guests. By sprinkling cayenne pepper in areas where rats frequent, you're not just adding a bit of spice to your space; you're setting up a defensive line that rats can't tolerate.

"The capsaicin in cayenne pepper, known for its irritating properties, causes discomfort to rats, effectively repelling them from your home."

Remember, moderation is key when using cayenne pepper as a rat repellent. The aim is to deter, not harm, rats.
