Rats can easily chew through softer materials like cardboard and plastic. They can even chew through harder things like wood and PVC pipes. But rats cannot chew through steel. They can't chew through anything stronger than iron.
Rats are afraid of human activity, mostly because humans are so much larger than they are. Rats also fear predators such as hawks, eagles, and other birds of prey. Other animals that rats are afraid of include your cat as well as rat terriers and other dogs that hunt rodents.
"Rats can certainly gnaw through concrete and metal, most normally soft metals such as tin, aluminium, copper and lead, but I have seen gnaw marks on steel, various hard plastics such as waste pipes and terracotta pipes — as well as concrete walls." Alice Sinia, an entomologist and technical advisor with pest control ...
What scent will keep rats away? Rats don't like the smell of peppermint, so placing peppermint oil on cotton wool balls in corners of your home will help to keep them away. Replace this every few days to ensure they keep their distance.
Some people have found that they can deter rats from coming onto their property by using certain smells and aromas. The most effective smells are essential oils, specifically; peppermint, castor, and citronella. These are good choices because while their smell is powerful, many people also find the aromas pleasant.
Shards of broken glass should be mixed into the concrete to deter the rats from trying to gnaw through it. Opening for utilities in walls between rooms within one building should also be sealed this way to prevent rats from moving from space to space within the building.
The article by Apartment Guide (2020) also tells how rats hate the sound of aluminum foil and hence making balls of aluminum foil and spreading it out throughout the house keeps them away. Another simple technique to get rid of rats is to use repellents which are not poisonous.
Aluminum foil often shows up on blogs as an anti-rodent "life hack," but this is at best a mild deterrent; rats will sometimes even take the foil to insulate their nests. Covering your fruit bowl might not be a bad idea, but papering every kitchen surface in foil might annoy you more than the rats.
They use their sense of smell… more or less how you'd expect. Rat's noses give them an unerring understanding of the specific location and distance of all kinds of food. They can smell food through packaging, walls, or pantry doors! All rats have to do to access that food is follow their noses all the way to it.
Essential oils are some of the best natural rat repellents. Rats have a highly developed sense of smell, which makes strong odors such as pine oil, cinnamon oil, and even peppermint oil offensive to them. Cayenne pepper, cloves, and a mixture of vinegar and ammonia will keep rats away as well.
Rats are known for their abilities to chew through walls, floors, insulation, wires, piping, and almost everything else found in your house. Rats can inflict significant damage to your home. This can be especially true when they chew through electrical wires, resulting in fires (5).

You can repel rats from your home and garden with scents they dislike, such as clover, garlic, onion, hot peppers containing capsaicin, house ammonia, used coffee grounds, peppermint, eucalyptus, predator (cat) scent, white vinegar, and citronella oil.
Baking soda combines with the stomach acids to produce carbon dioxide gas which rats are unable to tolerate. In turn, it builds up within their system and eventually causes internal blockage and rupture. Soon enough, you will have the rat-free environment you always deserved.
Electronic rat traps are considered the most modern and effective traps for rodents. These traps lure rodents with food and baits them onto a metal plate inside that immediately electrocutes them. It is the most humane approach in comparison to snap traps and poisonous traps – the rat's death is nearly instant.
Rats and mice can cause structural damage to homes, apartments, offices, and virtually any type of building through gnawing, nest-building, and defecation: Mice will chew on just about anything that they see as useful in building their nests. This could be wood, paper, cloth, books, etc.
USE DRY ICE. When a burrow is near a porch or more urban area, Mikulski said she uses dry ice. The dry ice produces carbon dioxide, which anesthetizes the rat and kills it. "It's very humane, it's very quick, it's very effective," she said.
Seal any holes you find to stop rodents from entering. Fill small holes with steel wool. Put caulk around the steel wool to keep it in place or use spray foam. Use lath screen or lath metal, cement, hardware cloth, or metal sheeting to fix larger holes.
Sometimes you might want to flush out the burrow first to force out any rats inside. You can do that by using a hose to fill the burrow with water. This stops the rats inside from digging new holes after you've close them. Don't attempt to fill the burrow with dry ice, poison, or bleach to kill the rats inside.
Vinegar has an unpleasant smell and if used in the pipes and u-bend it may temporarily keep them away. It can sting and would be unpleasant for the rat. Any strong smell may be enough to deter a rodent as it will make them wary that something has changed in the environment.
