What Are Signs Of Rat Infestation

Signs Of Rats And Rat Infestations

If you've heard scratching noises or noticed small brown droppings, you may have a rat infestation. Since rats are more active at night, identifying the signs of a rat infestation is easier than identifying actual rodents.

Rats can be identified by their droppings, gnaw marks, holes, nests, clawing, and footsteps. If you notice any of these indicators, act quickly to prevent the infestation from spreading.

What Draws Rats into Your Home?

Numerous things can lead to a rat infestation. Rat infestations are most frequently brought on by structural damage, litter, broken plumbing, and food. Rats find it simpler to enter your home the more cracks and holes there are. If there are weak spots, rats may be able to enter easily.

Rats will have more locations to hide and build nests in your rooms the more clutter you have. Rats are attracted to any type of grain stored in cupboards, and people often leave food out in the open. Open rubbish bins, pet food, and unclean dishes all serve as attractants for mice and rats.

How to Identify Signs of Rats:

 Rat Droppings

Rats can produce up to 40 droppings every night, thus they are often concentrated in certain areas. Brown rat droppings are huge grains of rice-sized, dark brown, tapered and spindle-shaped.

 Rub Marks

Due to their limited vision, rats follow established paths along skirting boards and walls. They brush against walls and surfaces, leaving smudges and black stains from the grease and dirt on their bodies.

 Gnaw Marks

Black rats are skilled climbers, which gives them the nickname "roof rat". Wires, cables, and other materials with gnaw marks are seen in lofts. Brown rats generate a grinding sound with their teeth, which can be used to identify them.

 Rat Nests

Rats often build their nests underground, but they may also be found in lofts, attics, beneath eaves, and even inside hollow walls. Making nests by using any accessible materials, including cardboard, loft insulation, and soft objects.

 Rat Holes

The large tunnel systems that brown rats dig and excavate serve as their homes, places to store food, and places to breed.


In dusty sections of structures, rats create foot and tail prints. You can sprinkle a powder around to determine if an infestation is present.

Rat Infestation Health Risks

It's possible for rats to infect people with sickness. By biting or scratching people, as well as by leaving their waste and urine around the house, they can spread disease. When rats contaminate food or scurry over counters where food is later cooked, humans might also become ill.

Rats, mice, and other rodents are carriers of diseases that are hazardous to both people and other animals. Rat urine or faeces can be directly contacted, together with rat bites, to cause the hantavirus pulmonary syndrome.

People who swim or drink contaminated water run the risk of contracting leptospirosis.Rat-bite fever is contracted by being bitten by a rat or coming into contact with a dead rat, whereas salmonellosis spreads through contaminated food and water.

Hantavirus infection in humans results in a severe respiratory condition known as hantavirus pulmonary syndrome (HPS). Anyone who has contact with rodents that are hantavirus carriers is susceptible to HPS. The major source of Hantavirus exposure continues to be rodent infestation in and around the home. If exposed to the virus, even healthy people can get HPS.

Hantavirus pulmonary syndrome is a viral illness that starts off with flu-like symptoms before getting worse. It might lead to deadly heart and lung issues. The virus can be discovered in rodent urine, faeces, or saliva. Block access since rats and mice can fit through openings as tiny as 6mm. Clothe holes with cement, metal flashing, steel wool, or wire mesh. Store your food in rodent-proof containers, wash your dishes as soon as possible, and clean your floors and countertops.

Leptospirosis is spread by rat urine that has been contaminated. After coming into touch with polluted water or urine, the germs enter your body through wounds, scratches, or the lining of your mouth, throat, and eyes. In the UK, it is an uncommon disorder.

The illness begins with flu-like symptoms including a headache or aches in the muscles. Meningitis, renal failure, and other catastrophic diseases might result from more severe instances as the illness can have a deadly outcome.

Between three and twenty-one days after the infection, symptoms might appear. Leptospirosis can have two different stages. First-phase signs and symptoms include high fever, excruciating headache, chills, muscular pains, and vomiting, and can involve a rash. In mild situations, the patient will recover after the first phase, but they may experience lethargy and depression for a while thereafter.

These may linger for 3 to 5 days until recovery. All the earlier symptoms as well as the possibility of jaundice, red eyes, abdominal pain, and diarrhoea are present in the second phase. Meningitis symptoms may resemble these, and severe instances may result in liver or kidney failure.

Heart, liver, or respiratory failure brought on by this condition might result in death. S.moniliformis and S.minus bacteria are the culprits behind the severe condition known as rat-bite fever (RBF). Rat bites and tainted food or drinks can spread these pathogens to people. RBF results in vague symptoms including fever, joint discomfort, and nausea.

RBF can cause serious issues including endocarditis, an inflammation of the membrane lining the heart if it is not addressed. Vomiting, headaches, muscular and joint pain, rashes, and fevers often appear 3 to 10 days after coming into contact with the disease.

However, they can also appear up to 3 weeks later. Any rodent bite or scratch wounds that resulted in the illness have often healed by this point. Within 2 to 4 days of the onset of the fever, the hands and feet may develop a rash that resembles flat, reddened areas with small bumps. One or more joints may then swell, turn red, or become painful.

Salmonellosis - Rat Pest Control Portsmouth, Southampton, Basingstoke And Hampshire

A Salmonella bacteria infection results in a sick state known as salmonellosis. Salmonellosis is uncommon in pet rats, and it is caught through food and water contaminated with faeces, urine, and bedding. This virus is categorised as having zoonotic potential because infected rats can serve as possible sites for transmission of this sickness to humans as well.

The best way to manage salmonellosis is to stop the infection from spreading. The most common symptoms of a Salmonella infection are diarrhoea, fever, and cramping in the stomach. After infection, symptoms often appear six hours to six days later and remain for four to seven days. However, some individuals do not experience symptoms for several weeks after infection, while others do.

Salmonella strains can infect the neurological system as well as the urine, blood, bones, joints, and urine. Salmonella diarrhoea is usually curable, however, it may take some people a few months for their bowel habits to return to normal.

After Salmonella has cleared up, some people experience reactive arthritis, which causes pain in the joints. Reactive arthritis can be challenging to treat and might linger for months or years; reactive arthritis can cause eye discomfort and urination pain in certain persons.
