After infesting a property and establishing their presence, rodents aren’t very good at keeping their existence a secret. Rats and mice are good at staying hidden in as much as you will rarely see them running around in the open during daylight hours. But most people become aware of infestations soon after they begin because of the clues rodents leave behind. Droppings are one of the most obvious signs that you have a rodent problem. Mice and rats leave their droppings behind as they travel from their nests to their nearest food and water sources. Another clear indication that you’re sharing your home with unwanted guests is the noises they make.
Rats aren’t like cows or birds; they don’t routinely let out a cry or call. If they did, they wouldn’t be able to stay hidden for very long. Rats will squeak at one another to communicate, but there is evidence that they often do this at pitches human beings can’t hear. You are much more likely to hear the other noises they make as they build their nests, scavenge for food, and chew on anything they can get their teeth on.
Rats are agile creatures. They might not be able to compress their bodies in the way that mice can, but they can climb, crawl, and dig to get where they need to go. All of these generate noise, especially when they are occurring behind your walls or in your attic. If you have rats loose on your property, you will almost definitely hear some scratching sounds coming from unusual places.
Rats love to gnaw. In fact, because their teeth don’t stop growing throughout their lives, they have to gnaw on whatever they can to keep them at a comfortable length. If there are any rats on your property, you will have visible and audible signs of them gnawing on hard surfaces.
