Dead Rats Will Attract Maggots and Flies

One of the most obvious and disgusting side effects of dead rats is the proliferation of maggots and flies. Maggots are the larval form of a fly, and they will feast on rotting flesh.

If you have a dead rat in your home, you can expect to see an influx of these pests. Not only are they unsightly, but they can also be dangerous if they come into contact with food or drink. Flies can also spread diseases like E. coli and Salmonella, so it’s important to get rid of them as quickly as possible.

It Smells Really Bad

Rotting flesh smells bad, and that’s exactly what you’ll be dealing with if you have a dead rat in your house. The smell will be strongest near the carcass, but it can also spread throughout the entire home.

Not only is the smell unpleasant, but it can also cause respiratory problems and nausea. If the rat has been dead for a while, the odor may become so strong that it’s impossible to stay in the house.

Dead Rats Carry Diseases

One of the biggest dangers of dead rats is the fact that they can carry diseases. Rat-borne illnesses are a serious health hazard, and they can cause everything from mild discomfort to death.

Some of the most common rat-borne diseases include:


This is a serious bacterial infection that can cause fever, muscle aches, and vomiting. In some cases, it can lead to kidney failure and death. This is often caused by contact with rat urine or saliva.

Hantavirus Pulmonary Syndrome

This is a deadly virus that causes fever, chest pain, and shortness of breath. It can lead to respiratory failure and death. This can be caught by having direct contact with rat droppings and inhaling dust that is infected with their waste.


Plagues have occurred throughout history and it is often caused by direct contact with infected rats. This disease has killed millions of people over the years. Symptoms include fever, chills, and swollen lymph nodes. It can be treated with antibiotics if caught early enough, but it can also be deadly.

Lymphocytic Chorio-Meningitis

This is a virus that affects the central nervous system. It can cause fever, headache, and neck stiffness. In some cases, it can be fatal. This is most commonly spread through contact with rat saliva or urine.


This is a food-borne illness that is caused by contact with rat feces. It can cause diarrhea, fever, and abdominal cramps. It is often mistaken for the flu, and it can be fatal if left untreated.


This is also a serious bacterial infection that can be caught by contact with dead rats or inhaling bacteria from their waste. It causes fever and muscle aches. In some cases, it can lead to pneumonia and death.

Rat Bite Fever
