Rats, like mice, can squeeze through impossibly small gaps (anything down to the size of a 10p coin) and should never be underestimated as to their versatility and persistence when trying to enter a building.
RATS AND MICE ARE AGILE MAMMALS. A mouse can get through a small, 6-7 mm hole (about the diameter of a normal-sized pen) and a rat can get through a 20 mm hole.
Rats can fit into holes about 1/2 of an inch in diameter. Rats and mice are excellent climbers, swimmers, and even jumpers. All of these abilities, combined with the fact that rats and mice only require tiny openings, allows them easy access to most homes and structures.
Small rats can fit through a hole the size of a quarter, about 0.96 inches, and mice can squeeze through a hole that is ¼ inch in width. This must be put in consideration while rat-proofing your out houses.
By filling up the burrows and sealing up the entrances, you can discourage rats from living near your property. Not only does this destroy their home, filling a burrows disrupts the rats' daily routine—something rats hate. Such a disruption often causes them to leave and find new areas to make their nest.
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.
In order to prevent the entry of rodents into a structure, both rat and mouse holes should be sealed or blocked off. This can be done with a variety of materials, such as steel wool, caulk or expanding foam. Additionally, it is important to remove any food sources that may attract rodents, such as pet food or garbage.
This makes peppermint oil, chili powder, citronella, and eucalyptus the most common natural rodent repellents. Chemical smells, such as ammonia, bleach, and mothballs also work as mice deterrents.
A mouse can fit through a gap under a door just 6mm wide or through a hole 16mm diameter (roughly the size of your little finger). A rat can squeeze through a gap just 12mm wide and a hole about the size of your thumb.
Rats and mice can crawl through very small spaces (under doors, into crevices, etc.) and when they can't fit, then they simply gnaw and chew their way through. destructive to homes, and can carry germs that make people sick. They often make their nests in and around people's homes and office buildings.
As it turns out, there are several smells that these pests cannot stand, which means you can use them to your advantage. But what exactly do mice and rats hate to smell? Mice can be kept away by using the smells of peppermint oil, cinnamon, vinegar, citronella, ammonia, bleach, and mothballs.
Don't underestimate these little creatures– rats are strong (and determined) enough to open doors. Cabinets, cupboards, lids on containers, even your refrigerator door can easily be opened by a fairly motivated rat.
Having pets makes no difference. Rats are not deterred by cats or dogs.”
Flush Out the Hole
This is a good method to consider, and can also be humane if done correctly. Take your garden hose and apply water into the burrows. If a rat is present in the hole, the rodent will likely scurry out of the hole and abandon it for good.
Actually, yes. Peppermint essential oil has risen greatly in popularity for its effectiveness against deterring rats from the home and can even prevent them from showing up at all with the proper techniques in place.
Rats typically burrow down about 18 inches to nest (if they can't find an indoor home), but they are capable of digging much deeper if a foundation is in the way and they think food is on the other side. Predator pee probably isn't going to stop them. But your mention of steel wool and concrete is on the right track.
Mice and rats have somewhat collapsible rib cages. Their ribs have a greater capacity to flex than most other mammals, enabling them to flatten themselves temporarily to squeeze through narrow cracks.
Both rats and mice are good climbers and can climb vertical walls and "shimmy" up between walls and drain pipes. Rats are also excellent swimmers and have been known to enter premises through the water traps of the toilet bowl when infestations occur in the main sewerage system.

The 2mm x 2mm hole size will also keep out larger insects, such as bees, wasps and house flies. These products are used by pest control specialists, and are the industry standard for rodent protection.
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 fear becoming a meal for a snake.
Eucalyptus or Peppermint oil can repel rats because they hate the smell. Another way to use a rat's sense of smell against them is to plant peppermint and catnip in strategic places. Diatomaceous earth is non-toxic to humans, but it can dry out rats until they die.
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 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 ...
If a rat nest is disturbed or destroyed, the rats may initially move to another location, but they may return to the same area if conditions are still favorable. Additionally, rats have a strong homing instinct and can navigate their way back to their nest even if they have been moved to a new location.
Yes. It doesn't matter if they're in your garden, or in your house – rats are a dangerous pest that carries an array of serious diseases, which are harmful to people and pets. Not only that, but they can also chew on electrical cables, which can cause significant damage to your property.
