You might be surprised to learn that pest control has been a legal requirement for over 70 years. In 1949, the Prevention of Damage Act authorized a pest control program, giving local governments and licenced companies the power to perform pest control where there is an increased risk of damage from pests such as rats. Those who store or manufacture food products can also take action when there is a risk of contamination. In the same way, landlords need to understand their obligations in this situation because they are responsible for maintaining pest-free properties.
