The Health Risks Associated with Rat Infestations in Homes

Rats are more than just a nuisance—they’re a serious health hazard. While many Perth homeowners focus on the visible signs of infestation like droppings or scratching sounds, the real threat lies in the bacteria and viruses rats bring into your home.

In this blog, we break down the key health risks linked to rat infestations and explain why fast, professional action is essential to protect your household.

1. Disease Transmission

Rats carry and spread numerous diseases that can be transmitted to humans either directly or indirectly. Some of the most dangerous include:

• Leptospirosis – Spread through contact with rat urine, especially in damp areas like basements or kitchens. It can cause flu-like symptoms, liver damage, or worse if untreated.

• Salmonella – Rats contaminate food and surfaces with their droppings, leading to stomach cramps, diarrhoea, and vomiting.

• Hantavirus – Found in rodent droppings and urine, this virus becomes airborne when dried waste is disturbed and can lead to severe respiratory illness.

• Rat-bite fever – Though rare, this can be transmitted through bites or scratches and causes serious illness if not treated.

Even breathing in dust from contaminated areas in roof voids or behind cupboards can put your family at risk.

2. Allergic Reactions and Asthma Triggers

Rat dander (shed fur and skin), urine, and droppings can trigger allergic reactions in sensitive individuals. Children, the elderly, and those with respiratory issues are especially vulnerable. Rats nesting near air vents or HVAC systems can circulate contaminated air throughout your home, worsening symptoms and potentially triggering asthma attacks.

3. Contaminated Surfaces and Food

Rats are notorious for walking across benchtops, food storage areas, and cooking utensils. Even a single rat can leave behind hair, urine, and droppings that contaminate everything they touch. This puts your family at constant risk of foodborne illness.

Unlike some pests, rats don’t avoid human areas—they actively seek them out at night. If you’re hearing noises in the kitchen or finding chewed packaging in the pantry, you could already be facing a serious contamination issue.

4. Mental Stress and Poor Sleep

Ongoing rat infestations can also affect your mental health. The sound of gnawing or movement in the ceiling at night often leads to sleep disturbances and anxiety. Many people feel embarrassed or helpless when facing a recurring rat problem, which only adds to the stress.

Peace of mind comes not just from eliminating rats—but knowing your home is fully secured from future invasions.
