Problems Rats cause.
Rats have the potential to spread a wide variety of diseases around the home and garden. This is because they tend to live in environments such as drains, sewers, and rubbish where germs can be found. These can then be spread wherever rats go via their fur, feet, urine or droppings. The main diseases of concern are Weil’s disease, and food poisoning diseases such as salmonella.
Rats can also damage property by gnawing at wood, lead and soft metals, electrical wiring, water pipes, and drainage systems.
