The Health Risks

Rodents are “vectors” for various serious diseases, transmitted through their urine, droppings, saliva, and nesting materials. 

Hantavirus: A severe respiratory disease found in the droppings and urine of deer mice. It becomes airborne when disturbed (aerosolisation).

Leptospirosis: Bacteria spread through rodent urine. It can enter the human body through cuts or contact with mucous membranes (eyes/nose/mouth).

Salmonellosis: Bacteria from rodent faeces that contaminate food surfaces, leading to severe food poisoning.

Rat-Bite Fever: Caused by bacteria in rodent saliva or urine; can be contracted through scratches or bites.

Parasites: Rodents carry fleas, ticks, and mites that can transmit secondary diseases like Lyme disease or Bubonic Plague. 

Step-by-Step Decontamination Process

1. Preparation & Safety (Crucial)

Never sweep or vacuum dry droppings. This kicks dust and pathogens into the air for you to inhale. 

PPE: Wear a well-fitting N95 or FFP3 mask, rubber or nitrile gloves, and long sleeves.

Ventilation: Open doors and windows for at least 30 minutes before starting to air out the space. 

2. Saturation

Before touching anything, you must “knock down” the pathogens.

Disinfectant: Use a commercial grade disinfectant solution.

The Soak: Spray droppings, nests, and carcasses until they are thoroughly soaked. Let it sit for at least 20 minutes to kill the viruses and bacteria. 

3. Removal

Pick up: Use a dustpan and scraper along with paper towel to pick up the soaked droppings or nest material.

Bagging: Place all waste into a plastic bag. Seal that bag, then place it into a second bag (double-bagging) and dispose of it responsibly.

4. Surface Disinfecting

Scrubbing: Mop floors and wipe down countertops with disinfectant.

Fabric/Upholstery: Steam clean carpets or furniture where activity was present. Wash any contaminated bedding or clothing in hot water and dry on a high heat setting.

Dead Space: Check behind appliances and inside cabinets. Rodents love corners and insulation. 

5. Clean Up

Disinfect your gloves before taking them off.

Wash your hands thoroughly with soap and warm water immediately after removing gear.
