Rats can squeeze through small openings as small as a pencil lead, so it is crucial to seal all gaps and cracks that could give access to rats.

Air vents are another entryway for rodents to access buildings, often used by builders as an easy route for routing pipes and cables into buildings while leaving gaps that rodents can exploit to enter.


Roofs are one of the primary entryways for rats. These agile climbers can use trees, vines or power lines as means to gain entry.

Rodents can enter your home through gaps and holes as small as a nickel, so it is crucial that you inspect every corner of your house, sealing any potential points of entry for them.

At first, inspect your soffits for any openings, and carefully examine your roof sheathing to identify any slats or gaps which might allow rodents to gain entry into your home. This step is especially critical if your house features tile roofing or is covered with siding siding.


Chimneys are one of the primary entryways for rats. Not only can they provide shelter and warmth for these pests, but it’s an ideal place for them to nest.

Your chimney can be sealed to stop rats from entering and causing costly repairs to it, thus saving money over time. Sealing helps extend its life and ensure you avoid costly repairs – saving both money and effort in the long run!

When choosing a sealant for your chimney, it’s essential that it fits with the climate in which you reside. This will ensure it can withstand the freeze-thaw cycles and windy weather that could potentially impact its performance.

Sealing your chimney not only protects it but can also help stop mold growth on its masonry and block air flow into it, thereby increasing health risks to both you and your family. Respiratory infections, asthma attacks and lung diseases are just a few health problems associated with blocked airflow; sealing may prevent this from happening!

If rats are seen in your Alexandria home, it’s essential that you learn where they’re coming from and how you can keep them out. Rats seek food, shelter, and warmth and may gain entry through various entry points on your property.

Rats can often get into your home through holes or cracks measuring less than half an inch wide, making a thorough inspection necessary to detect them in time.

Keep a careful watch over foundation cracks and openings as well as where water, electric wires, sewer pipes, drain spouts, vents or any other holes meet – any should be sealed promptly. Also ensure all doors, windows and screens fit tightly to reduce chances of further leakage.


The garage is an ideal environment for rats, providing them with safe and warm shelter to live and thrive in. In addition, it serves as home for family cars and their contents – which makes sealing it off from rats all the more important.

To prevent rats from entering your garage, it is essential that you identify their entryways and seal them up accordingly. This includes areas under the door, on exterior walls and any wires/pipes running through walls.

Rats and mice often gain entry under the weather seal on garage doors by chewing through these seals to gain entry.
