How can I lower my risk of Hantavirus in my home?

What is Hantavirus?

Hantaviruses are a group of viruses spread mainly by rodents. In the UK, the risk to most people is low, but it can increase if you clean areas where mice or rats have been nesting. The virus can be passed on through contact with rodent urine, droppings, saliva, or contaminated dust.

You are most likely to be exposed in sheds, garages, lofts, outbuildings, and other places where rodents may shelter. Taking sensible precautions at home can greatly reduce your risk.

Keep rodents out of your home

The best way to lower your risk is to stop rodents getting in. Seal gaps around pipes, vents, doors, and windows, and repair holes in walls, floors, and roofs. Use wire mesh or suitable filler for larger openings.

Store food in sealed containers and keep bin lids closed tightly. Clean up crumbs and spills quickly, and avoid leaving pet food out overnight. Reducing access to food and shelter makes your home less attractive to rodents.

Clean up safely

If you find droppings, nests, or signs of rodent activity, avoid sweeping or vacuuming straight away. These actions can disturb particles and increase the chance of breathing them in. Instead, ventilate the area by opening windows and leaving it for at least 30 minutes if possible.

Wear rubber or disposable gloves, and use disinfectant or a bleach solution to soak droppings and nesting material before wiping them up. Put waste into a sealed bag, then place that bag into a second bag before disposing of it. Wash your hands thoroughly afterwards.

Take care in sheds, lofts, and garages

These are common places for rodents to nest, so extra caution is sensible. Before cleaning, wear gloves and consider a face covering if there is a lot of dust or droppings. Keep your movements gentle and avoid creating dust.

If an area is heavily contaminated, or if you are unsure how to clean it safely, contact a professional pest control service. This is especially important if the problem is ongoing or widespread.

Know when to get medical advice

If you think you may have been exposed and then develop fever, muscle aches, headache, tiredness, or breathing problems, seek medical advice promptly. Mention the possible rodent exposure so the clinician can assess your risk properly. Early assessment can be important.

Most homes in the UK will never have a Hantavirus problem, but good hygiene and rodent control are practical precautions. A tidy, well-sealed home with safe cleaning habits offers the best protection.
