Though rodents are small creatures, they can wreak havoc on your home and health. From chewing up your walls to spreading diseases, they are not critters you want crawling around your house. However, as winter sets in and temperatures drop, rodents are trying extra hard to get indoors – after all, they don’t like the cold either!

Sealing off rodent entry holes is the first step in preventing an infestation. While this task may seem simple enough, rodents are great at sneaking through even the tiniest of openings. Did you know that a mouse can squeeze through a hole the size of a dime? Rats only need a tiny bit more space – an opening the size of a quarter is usually large enough for them to fit through.

Knowing how to identify rodent entry holes is crucial in keeping these pests outside. To help you out, we’ve put together a small guide on how to find and seal rodent entry holes around your home.

What Do Rodent Entry Holes Look Like?

Rodent entry holes usually just look like small cracks or gaps. If the opening is heavily trafficked by pests, there will be signs of greasy-looking marks, gnawing, or fur. It’s important to be able to identify any openings to your home, as they could all be used as entryways by rodents and other pests. Here are some of the most common places that rodents enter homes:

  • Cracks in foundations
  • Holes or gaps around pipes
  • Gaps near windows or doors
  • Broken seals along garage doors
  • Loose shingles on your roof
  • Holes or gaps around gutters
  • Broken window or door screens

How to Seal Rodent Entry Holes

There are a few different ways that you can go about sealing off rodent entry holes, and the method you use will largely depend on what kind of opening you are fixing. Here are a few ways you can seal off rodent entry holes:

  • Caulk for small cracks and gaps: A bit of caulk usually does the trick for very small openings, such as cracks in your foundation or small gaps near windows.
  • Sheet metal for larger holes: If you have a larger hole that can’t be covered by some caulk, you could either perform a full repair, or use some sheet metal and screws to block off the opening.
  • Repairs around your home: Broken screens, loose shingles, gaps around your gutters, and other similar issues are usually best remedied by full-blown repairs. Makeshift coverings could be beneficial in the short term, but to keep pests out for good, we recommend investing the time and effort into formally repairing your home.

Why Do Rodents Enter Homes?

Even worse is how resilient these creatures can be; they can fit into tiny spaces, survive off of strange food sources, and withstand some pretty harsh conditions, which makes it difficult to stop an infestation once it’s started.

But, if rodents are so hardy and equipped to survive outdoors, why are they so determined to get inside your home in the first place? Well, similar to you, they want to live somewhere comfortable and convenient. Here are some of the main reasons why rodents are attracted to your home:

  • It’s warm and cozy. Especially when the winter chill sets in, rodents will begin to look for a warm place to stay. Because they’re warm-blooded animals, rodents need shelter when it’s freezing out. For that reason, your home may seem like the perfect place for them to get away from the cold.
  • There’s plenty of food sources. Food out in the open is like a free buffet for rodents. But, even if you properly store your food, these pests may still find strange things to snack on. Rats in particular will eat all sorts of things we wouldn’t consider edible, from compost material and garbage to pet waste and bar soap.
  • There’s moisture all around. Rodents need constant moisture to drink from, and your home likely has plenty of sources for them to choose from. Leaking pipes, pet bowls, dripping faucets, or a damp basement are all places that a rodent may be drawn to.

How to Keep Rodents From Getting Inside

Since many rodents would consider your home a paradise, it’s important to take the proper precautions to keep these pests outside. Some ways to keep rodents from entering your home include:

  • Fixing any cracks, holes, or openings. Rodents are small and can fit through surprisingly small spaces. Reducing the number of openings into your home can prevent rodents from crawling indoors.
  • Keep your trash covered – even outdoors. An uncovered trash bin can alert rodents that there’s food nearby, which can attract them into your home. Keeping a secure lid on your bin can keep rodents at bay.
  • Seal off any leaky pipes or faucets. Rodents are also drawn to moisture, so a leaky pipe or faucet can bring them into your home. Preventing rodents from entering your house is just another reason to fix any drips.
  • Keep all of your food carefully stored. Though rodents can eat all sorts of things, they’ll definitely be drawn to food that isn’t properly stored. Placing your snacks in airtight containers can limit the amount of food they have access to inside of your home, which may prompt them to find somewhere else to live.

United Pest Solutions, serving Seattle WA talks about the pests that trigger allergy symptoms.With the temperatures getting warmer and flowers starting to bloom, many people will start to experience the symptoms of seasonal allergies. But what if pollen isn’t the only cause of your sinus problems? Many people don’t know that common household pests such as cockroaches and rodents can also trigger allergy symptoms.

With May being National Asthma and Allergy Awareness Month, we at United Pest Solutions are sharing the pests that can cause allergies and what you can do to help prevent an infestation.


Everyone knows cockroaches are disgusting and can spread diseases and bacteria, but few know they can trigger allergy symptoms. Cockroach droppings, shedded skin, saliva, and other body parts from cockroaches contain proteins that can cause allergic reactions and worsen asthma symptoms, especially in older adults and children. Symptoms may include congestion, coughing, ear infections, and rashes.


Like cockroaches, mice and rats are also known to be nasty critters. They can spread diseases and viruses, including salmonellosis, hantavirus, and rat-bite fever. Rodents can also trigger allergy and asthma symptoms through their saliva, skin, urine, and dander–which can get into the air as these pests scurry around.

Top Pest Prevention Tips

Exposure to cockroaches and rodents can be dangerous. But because both of these pests are nocturnal, most homeowners don’t even know they have an infestation. We recommend the following tips for protecting your home against pests that trigger allergy and asthma symptoms.

  • Seal cracks and crevices around your home, paying attention to areas where utilities and pipes enter
  • Seal holes in screen doors and windows
  • Store food in airtight containers
  • Regularly throw out trash
  • Clean up crumbs and spills immediately
  • Eliminate areas of standing water
