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 metal, cement, hardware cloth, or metal sheeting to fix larger holes.
Both ammonia and vinegar have sharp, acrid odors that rats detest. Ammonia mimics the smell of predator urine, creating a sense of danger, and vinegar's acidic smell irritates their sensitive noses.
Close and Fill
Inactive burrows: Fill the hole with dirt, then stomp or tamp it down with a shovel to compact the soil. Check back in a few days to see if rats have re-excavated the burrow, which would indicate it is still active. Active burrows: Stuff the entrances with steel wool to prevent the rats from re-entering.
Foam reinforced with hardware cloth, steel wool or metal insect netting is very effective. But you have to establish a perimeter, if you just block one spot they'll find another.
Outdoors, rats face a variety of predators. In these environments, large birds of prey — including hawks, falcons and owls — feed regularly on rodents. Owls are particularly formidable predators, as their nocturnal behavior ensures that they are most active when rats go out in search of food.

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.
A typical burrow will house a family of approximately eight rats. By counting the burrow holes gardeners can estimate the number of rats living in their garden.
Flushing out rat holes with water can be an effective and relatively humane method for driving rats from their burrows. To employ this technique, take your garden hose and thoroughly flood the burrows with water.
Rodents do not like the sharp scent of vinegar, so it's believed that it can be an effective rodent repellent. Common advice is to soak cotton balls with vinegar and place them near areas where you think rodents are entering your home and to use vinegar as a cleaning solution.
Mothballs are useful when kept in a closed container with the items you are trying to protect. However, leaving mothballs out in the open to repel rodents is a very bad idea. Mothballs are ineffective as a rodent repellent.
Essential oils that may be helpful in repelling rats and mice include peppermint oil, lemon oil, citronella oil, and eucalyptus oil. You can make an essential oil spray by mixing 2 teaspoons of oil with 1 cup of water or rubbing alcohol in a spray bottle. Then spray it anywhere you see traces of rodents.
Peppermint. Prepare to turn your rat problem into a minty-fresh solution! Rats may have a perceptive sense of smell, but they can't stand the refreshing scent of peppermint. This natural and aromatic repellent works wonders in deterring these unwanted pests.
Spraying the perimeter of your yard with garlic, clove, chili powder, peppermint, cat urine, or any other kind of rodent repellent outdoors might work in the short term. But if you keep using the same spray the rodents will probably get used it as it wears off.
Cover the edges of doors, windows and screens, which can be gnawed, with sheet metal or hardware cloth. Make a collar around pipe and wire openings into the house with pieces of sheet metal or tin cans. Rats cannot easily gnaw through metal. Fasten floor drains tightly to keep sewer rats from coming in.
Bait with Rodenticides
Bait stations using rodenticides (rat poison) are effective ways to get rid of rats permanently. To give yourself the best possible chance of catching a rat in the trap, keep the bait small and in the centre of the trap. There are numerous problems associated with mixing poison with edible bait.
Ammonia: ammonia has a very harsh chemical smell to it so it may not be so appealing to you as an option, however, it is an effective rat deterrent if all else fails.
Smoke Out The Holes
Begin by lighting the smoke bomb or smudge stick and place it at the rat hole's entrance. The smoke will infiltrate the burrow and drive the them to the surface. Once the rats have evacuated, seal the entrance to prevent them from returning.
So What Kills Rats Instantly? The only safe and viable method that will kill a rat instantly is a snap trap. Poisons can take up to a week to kill the rats and other types of traps will not provide an instant kill, and will even cause severe suffering.
Rats are nocturnal animals that prefer to move around under the cover of night; however, sleeping with lights on will not keep rats away. While it makes logical sense that rats would not like being in the light, it is not enough to discourage them from moving around your home at night.
