Diseases these rodents spread!!

By Blue Star Pest ServicesPublished 10 months ago 5 min read

During winter seasons, it is very common to have uninvited mice in your house. What most people don’t understand is that aside from nuisance, these pests bring dangerous diseases within. Rodents such as rats look like very innocent creatures but are linked with various health risks, in fact, rats and mice are known to spread more than 34 types of diseases.

These diseases can be spread to humans directly through contact with rodent feces, urine, saliva, and rodent bites, also the handling of live or dead rodents. The disease can spread to humans through fleas, ticks, or mites that have been in contact with infected rodents.

Why Are Rats Attracted To Your House?

Several factors attract rats to your home. Here are a few:

Food sources: Rats are attracted to food, so if there are open containers of food, dirty dishes, or crumbs left around your home, rats are likely to find them and make themselves at home.

Clutter and debris: Rats like to hide and nest in cluttered and messy areas, so if you have piles of boxes, papers, or other trash, it can provide a perfect home for rats.

Entry points: Rats can squeeze through very small holes and cracks, so they can gain entry if there are openings in your home's walls or foundation. Common entry points include gaps around pipes and vents, cracks in the walls, and holes in the roof or soffits.

Outdoor environment: An overgrown yard or garden can provide a perfect place for rats to nest and hide. Similarly, if there are nearby food sources, such as bird feeders or compost piles, rats are likely to be attracted to your property.

Climate: Rats are more likely to seek shelter inside homes during colder months, or when there is heavy rain, so it's important to take extra precautions during this period.

Diseases These Mice Spread

Hanta Virus

This disease causes severe fever caused by the intact to the dropping or rine of rodents that carry the virus. About 3-5 Hantavirus cases have been reported, leading to death. It is very important to be careful and take precautions while cleaning mice droppings from sheds, cabins, or storerooms.’


This disease is caused by a bacteria known as leptospira, which infects animals and humans both. It is most common in tropical areas but occurs worldwide too. Some people infected with Leptospirosis get too ill, and some are not affected at all.

Some animals, such as pigs, dogs, raccoons, cattle, and rodents, carry these leptospira bacteria within themselves and passes this disease through urine. Soil or water contaminated or exposed to this urine is most likely to cause this disease in humans as well.


This disease occurs due to the bacterium Francisella tularensis. It is commonly spread through contact with infected animals, including mice and other rodents, rabbits, and hares. The bacterium transmits to humans through bites from infected ticks, deer flies, or other insects or through contact with contaminated water, soil, or food.

Tularemia can cause various symptoms in humans, including fever, chills, headache, muscle aches, joint pain, cough, and difficulty breathing. It can lead to pneumonia, meningitis, and other complications in severe cases.

You can prevent this disease by taking precautions when handling animals or spending time in areas where animals are infected. This includes wearing protective clothing, using insect repellent, and avoiding contact with dead or sick animals.

If you suspect you may have been exposed to tularemia or are experiencing symptoms, it is important to seek medical attention immediately. Treatment typically involves antibiotics; early diagnosis and treatment can help prevent serious complications.


The plague is a bacterial disease caused by the bacterium Yersinia pestis, which spreads through the bites of infected fleas that live on rodents such as mice and rats. In areas with high rodent populations, such as urban or rural areas with poor sanitation, people can become infected with the plague through close contact with infected animals or by handling their carcasses.

The plague symptoms include fever, chills, weakness, swollen and painful lymph nodes, headache, and muscle aches. The disease can sometimes progress to more severe forms, such as septicemic or pneumonic plague, which can be life-threatening if not treated promptly with antibiotics.

Preventing the spread of the plague involves controlling rodent populations and taking precautions to avoid contact with infected animals or their fleas. This includes practicing good sanitation, using insect repellent, and avoiding handling wild animals or their carcasses.

What To Do If You Have A Mice Infestation In Your Home?

If you suspect a mice infestation in your home, taking action as soon as possible is important to prevent further damage and potential health risks. Follow these steps to eliminate them from your home.

Identify the problem: Look for signs of mice, such as droppings, chewed materials, or gnaw marks on furniture or walls.

Eliminate food sources: Mice are attracted to food, so make sure to keep your kitchen and pantry clean, store food in airtight containers, and dispose of trash properly.

Close entry points: Mice can enter your home through small cracks and openings. Seal any gaps or cracks in walls, floors, and around pipes with steel wool or caulk.

Set traps: There are different types of traps available, including snap traps, glue traps, and electronic traps. Place traps where mice are likely to travel, such as along walls or corners.

Consider using repellents: Natural and commercial repellents may help deter mice from entering your home.
