Early Signs of Rodent Infestations You Should Never Ignore

The unfortunate truth about rodents is that you can find them wherever you go. Whether it’s rats in the city or field mice in the suburbs and country, it can be hard to avoid them unless you safeguard your home against infestations. New Jersey is no exception, and homeowners here often find themselves shooing mice or rats out of their homes, especially as the weather begins to turn cold.

While the DIY approach to rodent control in Avalon, NJ isn’t always enough to truly protect your family and home from these unwelcome pests, there are certainly ways to prevent infestations in the first place—and most of them start with identifying early signs of rodent infestations. Let’s get into what you should keep an eye out for in your New Jersey home to help avoid rodent problems this year.

What Are Signs of Rodent Infestations to Look Out for in Avalon, NJ?

When you have rodents in your house, it’s not always obvious at first, especially if you’re busy with kids, working full-time, and other responsibilities. But, if you keep your eyes open for signs, you’ll know an early infestation when you see it. 

Here are a few commons signs of rodent infestations to look out for in your home, ordered from least to most obvious:

  • Grease marks along your walls (caused by mice or rats walking the same path, usually against your walls where they crawl)
  • Persistent, musky smells (this is caused by their urine and droppings)
  • Small holes in your foundation, walls, or around utility lines (remember: mice can squeeze through the teeniest holes, even as small as a dime!)
  • Chew marks on pantry items, food packaging, wires, insulation, or even baseboards
  • Scratch marks on walls and baseboards
  • Scratching, scurrying, or chewing sounds come from inside walls, attics, and ceilings at night
  • Mouse droppings (they’ll look like small, dark pellets and appear around drawers, pantries, cupboards, or other areas where food is kept)
  • Nests in hidden areas, typically built with shredded materials like paper, insulation, cardboard, or fabric

Why It’s Important to Act Quickly if You Suspect Rodents in Your Avalon, NJ Home

Where one rodent appears, more will soon follow, primarily through rapid reproduction—and suddenly, you have an infestation on your hands. Once the infestation exists, your house can suffer serious property damage, and your family’s health is at risk from the spread of diseases and food contamination that rodents can cause. Plus, this doesn’t even include the additional allergy and respiratory problems your family can suffer from the urine and droppings that rodents leave behind.

That’s why hiring a professional for rodent control in Avalon, NJ is so important. Rather than approaching the problem yourself, an experienced company will send highly trained technicians to your home to address the root cause of your infestation and use the appropriate tools and equipment to remedy the problem.
