Roof rats are long and thin rodents that have large eyes and ears, a pointed nose and a scaly tail. Roof rats have soft and smooth fur that is typically brown with intermixed spots of black. Their undersides are often white, gray or black.
Roof rats may have black, gray, or brown fur, and a long naked tail that is long enough to be curled around to touch the end of the rat's nose. They have relatively slender bodies compared to Norway rats, and larger ears and eyes.
Roof rats have black fur with pale underbellies, while Norway rats have brownish-gray coats. Another way to differentiate between the two rodents is size. Adult roof rats measure about eight inches in length, while Norway rats can be up to ten inches long. Additionally, the roof rat typically has a much longer tail.
Roof rats destroy property, and can cause fires or shorts with their constant gnawing. More importantly, roof rats are a threat to human health. They contaminate food with their droppings and urine (which can lead to food poisoning) and may carry fleas, parasites, and disease that can cause serious illness.
Rats and mice are nocturnal with most activity taking place between approximately one half hour after sunset to about one half hour before sunrise.
Natural deterrents utilize scents or substances that roof rats find unpleasant to keep them away from the house. Mothballs, chili pepper flakes, garlic, and peppermint oil, clove oil, or tea tree oil are all effective deterrents that some homeowners may already have on hand.
Smells and Odors that attract rats
Odors and smells that come from pet waste, pet food, garbage containers, barbecue grills, birdfeeders, and even from unharvested fruit and nuts from plants can attract rats and mice.
Typically living in colonies, roof rats prefer to nest in the upper parts of buildings, such as attics and rafters. They can also be found under, in and around structures, as well as in piles of wood or debris.
Roof rats are prevalent in many parts of the U.S., including Southern California. The bad news is that roof rats can wreak havoc on your home if not appropriately eradicated.

to eliminate sources of food, shelter, and water. Denied food, rats will turn to killing and eating each other, further reducing the infestation. Rats cannot live without food, water, or shelter.
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.
Rat Sounds in Attic
These nocturnal pests typically enter homes through basements, subfloors, and hollow walls, though some species, such as roof rats, are particularly common in the attic. Noises at night, such as gnawing, clawing, scratching, or squeaking, are usually the result of rats communicating with each other.
The sounds of rats you will hear are movement noises. You can hear scratching, gnawing, and rustling in your attic or inside walls. Rats also chomp and grind their teeth (bruxing). Not only do rats infest homes and cause costly damage, but they also lead to health problems.
Rats are social animals, so if you see one rat then there are likely to be more nearby. Rats have the ability to jump around three feet into the air, four feet horizontally and can fall from a height of up to 50 feet without getting injured.
Rats are social creatures and need the company of other rats. They use their sense of smell to recognise others, finding out about where they've been and what they've been doing. As rats are social animals, they can get depressed and develop abnormal behaviour if they live on their own.
Rats may also be more likely to come out during the day when they are accustomed to being around humans. However, rats are generally more nocturnal because they are more difficult to spot by predators, such as hawks and other birds of prey at night. It's not unusual to see rats during the daytime.
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.
The smell of peppermint, chili pepper, eucalyptus, citronella, and sagebrush are all effective at keeping rats away if applied in the right concentration. They are also deterred by chemical smells like ammonia and bleach.
Keeping your home clean, particularly your kitchen, discourages a rat infestation. Rats and mice will also rummage through trash to find food. You should cover and remove waste from your home to deter rats from exploring your garbage.
Rats and rodents in general are very sensitive to sound, since it's one of their main tools for survival. Any new or unexpected noise will frighten them and send them scurrying. However, once rodents get used to a sound, they will no longer fear it.
Roof rats can enter through a small hole the size of one-half inch. They also chew their way through entry holes, gaps in the roof, fitting through cracks and crevices. Roof rats prefer to stay in elevated places, so it's likely you'll spot them climbing on trees, telephone lines, or in the attics of homes.
Rats make noises which may occur when they are excited, or leaping from one spot to another within the roof space. You may even hear loud thuds at times as the rats land on the ceiling and scamper around. The disturbance is louder in roof spaces that do not have insulation.
