Critters have the uncanny knack of making their homes in less than ideal places. Many animals will happily make the home under the house. Unfortunately, these unwelcome visitors can lead to unpleasant odors and other issues for the residents of the house.

Let’s explore the types of animals found under the house. Plus, how to remove them.

What Types of Animals are Found under the House?

The space underneath your house presents the perfect opportunity for many animals to create a cozy home. Although it might seem dank and dark to you, some critters enjoy the security offered by the bulk of your home overhead.

Here are a few of the most common critters that you’ll find under the house:

  • Skunks. Skunks may find the perfect spot to create a den under the house.  
  • Raccoons. Raccoons enjoy taking shelter in the crawlspace and area under your porch.
  • Opossums. Opossums may use the space under your house to sleep until night falls.
  • Chipmunks. Chipmunks can burrow under the house to cause structural damage in pursuit of a home.
  • Rabbits. Rabbits may create a burrow under your porch or under your crawlspace.
  • Armadillos. Armadillos are nocturnal animals that may dig small burrows under the house.
  • Moles. Moles spend the majority of their time underground and may find themselves under your house, causing foundational issues with the tunnels they build.
  • Voles. Voles build elaborate tunnel systems which could lead them directly under your foundation.
  • Woodchucks. Woodchucks (or groundhogs) live in burrows dug straight down into the earth. Groundhogs prefer wide-open spaces like crop fields, meadows, pastures, near wooded areas, and even in weedy patches near roadways. 
  • Mice. Mice may set up shop under the house in order to have easy access to food stores within your home.
  • Rats. Rats may create burrows under the house to access the food within easily.

Each of these animals finds the area under your house as an ideal location to live in. But when these animals move in, they can bring unpleasant odors and dangerous diseases to your doorstep.

Why Do animals Get Under the House?

Primarily, animals choose to get under the house for the shelter it can provide them.

Most animals you’ll find under the house are likely making their way there to create a burrow or nest. The dark space offers shelter from the elements, making it the perfect spot to call home.

Beyond simple shelter, the space under your house provides close proximity to the food opportunities that come with human presence. For example, they may be chowing down on the food in your garden, eating the food left outside for pets, or taking advantage of any food available in your garbage.

How Do Animals Get Under the House?

Different animals get under the house in different ways. Here’s a closer look at a few examples.


Animals may find their way into your crawlspace if there is a big enough hole to squeeze in. Once inside, the critter may create a den.

In your crawlspace, a few animals you might find include raccoons, opossums, skunks, rabbits, mice, armadillos, and rats.

Under the porch

Like the crawlspace, the area under the porch is an ideal spot for many animals to create their home. If there are any holes available for an animal to slide into the porch, then you might have an unwelcome houseguest on your hands.

Some animals that enjoy making their home under the porch include raccoons, opossums, skunks, rabbits, mice, armadillos, rats, and skunks.

Under the foundation

The foundation of your home attracts a different kind of critter. Typically, you’ll find smaller mammals that build a series of tunnels underneath the foundation. Chipmunks and moles are great diggers that can get underneath the foundation of your home. Homeowners in the states like Texas, Oklahoma, Louisiana, Arkansas, Mississippi, Georgia, and Florida can experience armadillos digging under their foundation.

An animal burrow under your foundation can be a risk. You will need to trap and remove the animal. We use specific live traps to catch critters like chipmunks, moles, and armadillos. 

How to Get Rid of Animals Under the House?

After you’ve discovered that there are animals under the house, you’ll likely want to remove them as soon as possible. Not only can these animals bring diseases to your door, but they also create extremely unpleasant odors to contend with.

Let’s explore how you can get rid of animals under your home.

Get Animal Out of Crawlspaces

If you find an animal living in your crawlspace, it is critical to determine where the animal made its way in. As you look for entry points, you might be surprised by the size of the animal when compared to the hold.

Here’s how big a hole needs to be for an animal to squeeze through.

  • Quarter-inch to 1 inch. Mice and voles.
  • 1 inch to 2 inches. Chipmunks.
  • 2 inches to 3 inches. Rats.
  • 3 or more inches. Raccoons, rabbits, opossums, skunks, groundhogs, armadillos, and more.

Depending on the animal, you might remove it via trapping, installing a one-way door, or simply waiting for it to leave for food. But ultimately, you’ll need to ensure there are no entry holes available to any animals that might return. You mighte tempted to try an animal-repellent to encourage them to leave. We have found most DIY animal repellents either are ineffective (apple cider vingear) or dangerous (mothballs). 

Get Animal Out from Under Porch

If you find animals under the porch, the first step is to evict the critters. Once the animals are gone, you’ll need to create effective exclusions. Typically, these exclusions will include wire mesh, hardware cloth, and buried fences to prevent more animals from entering. 

Do not use chicken wire. Rats and snakes can easily get through it. Stronger animals like raccoons or opossums can break it. 

How to keep animals from digging holes around the foundation

If you spot small holes in the dirt around your foundation, then you might have animals living under the foundation.

The first step is to fill in any holes that you see to stop the current residents from returning. Additionally, you may need to treat the area with odor-producing chemicals that warn potential pests from making their home under your house.

When you have wild animals under your house, the type of animal will have a big impact on the appropriate wildlife removal strategy. If you need help identifying and resolving an animal infestation, then it’s smart to call in professional help.

Critter Control Reviews

It has been very effective at reducing the number of mice, lizard, and snake sightings. During one visit Edgar removed a rattlesnake he came across. We may see a snake maybe two to three times during the spring and summer months, but it has been far less than before.

Full service. Excellent job of extracting raccoon, cleaning all animal waste, sanitizing, and spraying anti-parasitic substance. They closed all potential ports of entry, though the work did not match the vinyl, and it looks kind of tacky. They added blown insulation, which added a lot to the cost. They provide a one year warranty against animal intrusion, with an option to extend the warranty at the end of each one- year period. They were willing to work with me one the price. I will probably extend my warranty, and will definitely use them it the future.

I was really impressed by these guys. Got a call within a few hours of making an inquiry. Had a rep out to inspect the situation by the end of the week, and when they laid out the timeline they kept if not exceeded listed times.

Rob, Travis, and Jim were all professional, polite, and courteous and after months of hearing squirrels in my ceiling they are gone and the repair to my flashing looks excellent. Can't recommend these guys enough.

Jeff was incredibly professional and helpful. I'll use them again and would recommend them to anyone.

Critter Control did a great job of evaluating our house for sites of entry after we found bats and a squirrel in our attic. They completed their work promptly and professionally.

We heard some noise from the corner of our house. Concerned that it could be inside we called for an inspection. Jessy arrived as scheduled and conducted a complete inspection of our home. Based on a recording we made he determined we had a tree frog on our roof. I was pleased that we didn’t have any rodent in our house. And his inspection could a few spots I can tighten up around my house. I am very happy with the outcome.

We have a vacation home in Western Mass and haven’t been there much during the pandemic as we live and work in Atlanta, GA. On our most recent visit we noticed that we had some rodent intrusion as well as some un-welcomed wildlife who decided to make our vacation home their home.

We contacted Critter Control and Mr. Cahoon was quick to set up an appointment as we wouldn’t be in town very long. He came out and assessed our issues. He informed us of our options to both eradicate and control future intrusions. Keeping in mind that wildlife is wildlife! He quickly got to work eradicating the rodents and wildlife from our home and addressing the intrusion issues. We feel much better leaving our vacation home for periods at a time knowing that Mr. Cahoon and Critter Control did their job and did it right! Thanks again!

We bought an old cabin last spring , it was used for years as a summer vacation cabin, therefore maintenance wasn’t a priority. After our project to remodel started, we found evidence of mice droppings.

We immediately called Critter Control and they came and gave us a reasonable estimate to remove all remnants and insulation. They sanitized and replaced with new insulation and sealing up points of entry .

Seeing their professional work made us feel confident and secure that the problem was solved ! Everyone we worked with continued to show professional and respectful work. Highly recommend this company! We continue to use critter control monthly to be sure we are mice and bug free!
