Attract Other Pests, such as Insects and Other Rodents
Rats like to live together in groups. As they breed, they attract other pests that feed on their waste, like roaches and other rodents.
These pests multiply quickly and will quickly infest your home if you do not take action against them early on.
Contaminate Food
Rats love to chew on things that smell good or taste good to them. They will chew through cardboard boxes or wood crates if they smell food inside them.
This often leads to contaminated food or water supplies in homes or businesses where rats live because they leave droppings behind when chewing through these materials.
Droppings
Rats usually leave droppings wherever they go. Look for dark, oval-shaped droppings on countertops, floors, or other places where food is prepared or served, under sinks, in cabinets, near pipes, around drains, and in any other place where rats might roam freely during the day or night hours.
These droppings may also have blood stains on them if there’s been an injury or if they’ve been infected with a disease like leptospirosis or rickettsialpox (a flea-borne disease).
Create Noise
Rats tend to create noise at night while they’re searching for food or trying to escape from an area where they feel threatened.
The sound of chewing on wires can also be heard throughout the house, which may indicate that rats are nesting in the walls or attic.
