Critters In The Wall?

Critters In The Wall?

When it comes to the peaceful sanctity of our homes, one of the last things we want to imagine is that there might be unwanted guests living within our walls. While we all enjoy the occasional chirping of birds or the soothing sound of rain, critters in the wall can be a homeowner's worst nightmare. At Critter Stop we have prepared this comprehensive guide, where we will explore the various critters that might take up residence in your walls, the signs to look out for, and most importantly, how to deal with this unwelcome situation effectively.

Identifying the Culprits

Before we delve into the solutions, it's crucial to identify the potential critters that may be lurking within your walls. We have provided wildlife removal services over the years in the Dallas-Fort Worth area, based on our experience, here are some common intruders:

1. Mice and Rats

Mice and rats are notorious for finding their way into homes, especially during the colder months. They can squeeze through tiny openings and quickly establish nests within wall voids.

Signs of infestation: Look for droppings, gnawed wires, yellowy streaks on wires or pipes in the walls or attic (which is their urine), or scratching sounds within your walls or in your ceiling. You may also notice an entry point chewed on the exterior - mice only need an entry point the size of a dime and rats only need an entry point the size of a quarter!

2. Squirrels and Birds

These creatures are agile climbers and may find their way into your attic or walls. They can create nests and cause structural damage while also being noisy neighbors.

Signs of infestation: Scratching or scurrying sounds, nesting materials in your attic or walls, or visible entry points. Squirrels need an entry point of ~1.5" or larger to gain entry to a structure.

3. Raccoons

As raccoon removal experts, we know that raccoons usually follow other animals into your walls or attic, specifically mice and rats, which they will hunt. Many of our customers with raccoons in the attic either did not know they had rodents in the attic or did not view it as a critical problem.

Signs of infestation: Raccoons usually defecate in one specific area, known as a latrine. They also tear large holes to gain entry, usually ~4" or larger, in siding, attic vents, soffits, or shingles.

4. Opossums

Opossums can also find their way into your walls. They are less likely to create damage to gain entry, but rather they find pre-existing openings or use other animals' old entry points. Opossums are much less common in attics than raccoons.

Signs of infestation: Opossums usually defecate in a seemingly random matter throughout the attic. Unlike raccoons, opossums usually leave droppings sporadically throughout the attic. They also need an entry point of ~3-4" or larger.

Dealing with Critters in the Wall

Now that we've identified potential intruders, let's explore how to handle them:

1. Sealing Entry Points

As your trusted removal company, we always say that prevention is the first line of defense. Identify and seal any gaps or cracks in your home's exterior that critters could use to enter. This includes checking windows, doors, vents, and utility openings.

2. Humane Trapping and Removal

For smaller critters like mice or squirrels, humane trapping and removal is a compassionate way to deal with the issue. Once captured, release them far from your home.

3. Pest Control Services

For more severe infestations, consider enlisting the services of professional pest control experts. They have the experience and tools to safely remove critters and prevent future infestations.

4. Repairing Damage

After critters have been removed, assess and repair any damage to your home's structure. This step is crucial to ensure your home remains secure and free from future intruders.

5. Regular Maintenance

To prevent future infestations, maintain a regular cleaning and maintenance routine. Keep your home clutter-free, and inspect for any potential entry points regularly.

I’d give a 10 star review if I could! We had a great experience with Critter Stop. Everyone I dealt was friendly, professional, and reassuring. Phillip was very helpful and knowledgeable about the work he was doing. He walked me around the entire house to make sure I saw and understood the services he provided. He was also really nice and answered all my questions — he is exactly the type of person that should be interacting with customers.I love the fact that they will come back for up to 1 year after installation if any problems occur — this shows me they stand behind their work.The owner was great too, he personally came to my house and walked me through their offering. I recommend critter stop to anyone and everyone!

Critter Stop is a fantastic business! Everyone involved is extremely professional and very easy to communicate with. Chisam, the owner, did a great job of explaining the process to get the squirrels out of my attic during the initial free estimate. The exclusion crew who did all of the initial work was fabulous. The crew consisted of Phillip, Nick and Corey who arrived promptly when they said they would. They are happy, positive employees. Everyone is very polite and patient in explaining their work and answering questions. They came back several times to check the traps and finish it off with the fogging. Lester was very good about following up to schedule each trap check with me, and the office staff who took care of the billing was very efficient. Critter Stop is a well run company with honest, trustworthy employees! Thank you to all of you who worked hard to make my attic critter free and for the peace of mind that you guarantee your work. Great to know I can call them if for some reason a squirrel figures out a way to get back in!

The guys at Critter Stop responded quickly, were very friendly, and gave us an honest estimate of what we might need. They explained why some items on other quotes were or were not necessary. They communicated well to get us scheduled, and did the work well and quickly. Great service at a fair and competitive price.
