Can Rats Squeeze Under Doors? Surprising Entry Points You Should Know
When you think your home is sealed tight, rats might still find a way in. One of the most overlooked access points is right beneath your feet: your doors!
Can rats squeeze under doors? This unsettling question deserves a thorough explanation, especially if you have spotted signs of rodent activity around your home.
Rats are notorious for squeezing through impossibly tight spaces. In this article, we will discuss how they manage to slip under doors, the conditions that make this possible, and, more importantly, how to stop them.
If you have been dealing with rats or want to prevent an infestation, you will want to read this to the end.
Can Rats Squeeze Under Doors?
Yes, rats can squeeze under doors if there is even a small enough gap. An adult rat only needs an opening as small as 0.5 inch (about the size of a coin) to wriggle through.
Their flexible bodies and strong jaws allow them to slip into spaces that seem far too small for their size.
If the bottom of your door has a gap of half an inch or more, it could be a perfect entrance for rats, especially if they smell food or shelter inside your home.

How Do Rats Squeeze through Tight Spaces?
Can rats squeeze under doors? We have already established the fact that they actually can squeeze under doors, but how do they squeeze through these tight spaces?
Rats have a unique bone structure and cartilage that allows them to compress their bodies. As long as their head can fit through an opening, their body can follow. Here is how they manage this:
- Flexible Ribs: Rats have ribs that are not rigidly attached to the spine, allowing the ribcage to collapse slightly to fit narrow spaces.
- Strong Teeth: Rats can gnaw at door bottoms or thresholds to widen the gap just enough to get through.
- Whisker Sensitivity: Their whiskers help them determine if a space is large enough before attempting to squeeze through.
Why Do Rats Try to Enter Through Doors?
Doors, especially those leading to the kitchen, garage, or basement, often provide easy access to food or warmth. Common reasons why rats enter through doors include the following:
- Gaps from poorly installed or worn-out doors
- Unsealed garage doors or patio entrances
- Gaps in basement or back doors often ignored by homeowners
Even more concerning, once they have accessed your home, rats can establish nests inside walls, ceilings, or under floors, and this poses health risks and property damage.
How to Know If Rats Are Squeezing Under Your Doors
Here are telltale signs that rats are entering under your doors:
- Grease Marks: Rats leave oily residue from their fur on door edges.
- Gnaw Marks: Rats will chew door frames or rubber seals to widen access.
- Droppings: Rat feces near the door or just inside the room.
- Scuffling Sounds: Especially at night, you might hear movement near entry points.

How to Stop Rats from Entering Under Doors
Can rats squeeze through doors? Yes, they can, but how can you stop them from entering under doors? I suggest you try the following tips to block this access point effectively:
- Install Door Sweeps: Use heavy-duty metal or rubber door sweeps to seal gaps.
- Use Steel Wool: Rats cannot chew through steel wool, so you can use it to block small openings.
- Seal Cracks and Gaps: Do not forget to caulk any surrounding cracks in door frames.
- Install Threshold Seals: Weatherstripping can help close gaps under doors securely.
- Keep Areas Clean: Avoid leaving food or crumbs near doors, especially in the kitchen or pantry.
Other Surprising Entry Points Rats Use
Aside from doors, rats can enter your home through various hidden entry points such as:
- Broken vents
- Unsealed pipes or utility lines
- Roof gaps and attic vents
- Garage door edges
- Cracks in foundations
Protecting your home means inspecting and sealing off all of these weak spots; not just the doors.

- Spreading diseases like salmonella and leptospirosis
- Contaminating food sources
- Damaging insulation, wiring, and furniture
- Triggering allergies and respiratory issues with their dander
When to Call a Professional
