Rats like to live within sewers as it is provides warmth and a food source. The drains of your property connect into these sewers and need to be protected from rodent entry. You should look out for the following indicators for rodent activity within your drains:
- Scratching or gnawing sounds within walls, roofs, or floors.
- Burrowing holes near manhole chambers.
- Rat droppings within manhole chambers.
