Have you noticed pesky little holes in your concrete walkway or patio? Chances are these aren’t just accidental marks created by passers-by. Most likely, they are the handiwork of an unwelcome guest – a rodent.

To avoid any further damage to your concrete structure and potential infestation, it’s important to fill those rodent holes as soon as possible. This blog post will explore ways how to fill rodent holes under concrete effectively – giving homeowners and business owners the necessary information they need to confront this problem head-on.
Can You Put Cement in Rat Holes?
Yes, you can fill rodent holes in concrete with cement. First, sweep out the area around the hole and make sure it is free of debris. Then use a shovel to dig out any dirt or soil from the hole. Make sure the area is dry before filling it with cement.
Mix a small amount of cement with water to create a paste-like mixture. Use this mixture to fill in the rat hole until it is level with the surrounding surface. Allow for proper curing time before walking on or using the filled area again.
It’s important to note that if there are rodents actively living inside these holes, then they should first be removed before attempting to seal them off, as it will likely not keep new ones from entering if they are still living inside.
Additionally, it is important to use quality materials and follow the recommended steps for filling rat holes in concrete to ensure that the area is sealed properly. This will help prevent further damage from occurring and create a strong, durable surface.
Does Cement Stop Rats?
Many people ask whether cement can be used to stop rats from getting into their homes. The answer is yes, but it requires a few steps in order to be effective. First, any existing holes or cracks should be filled with expanding foam, and if possible, metal mesh or wire mesh should be placed over the opening as an extra measure of protection.

Once this is done, then the area can be sealed up with cement. This will not only help block out any rats that may try to get in, but it also serves as a physical barrier that will make sure no new holes are created by rodents.
Additionally, using concrete helps keep moisture away from walls which could otherwise attract pests such as termites and other insects. While there are many ways to keep rats and other pests out of a home, using cement is one of the most effective methods.
It’s important to note that sealing holes with cement is not foolproof, and it should be done in conjunction with other measures such as good sanitation, removal of debris and food sources, and use of traps or poisons.
Additionally, if you’re dealing with an existing infestation, then it’s important to call a professional pest control company to help eliminate the problem. But if you’re looking for a long-term solution to keep rats out of your home, then sealing up holes and cracks with cement is definitely worth considering.
What Chemicals Keep Rats Away?
If you want to deter rats and mice from coming back, there are a number of chemical products that can be employed.
One option is to use rodent repellents, which work by creating an unpleasant scent for the rodents.
This type of product typically consists of natural essential oils such as peppermint, clove oil, castor oil, or ammonia. Other chemical solutions may include rodenticides, which can be applied directly around the hole or in bait stations and are designed to kill rats and mice that come into contact with them.
It is important to follow all safety instructions carefully when using these products. For best results, use a combination of both repellents and rodenticides for maximum control.
Additionally, you can also combine chemical methods with physical tactics such as sealing off entry points or trapping rodents before they have a chance to enter your home or property.
Regularly inspecting your property and taking steps to prevent new burrows from forming is key to long-term success in keeping rats away from your home or business. If you believe that there are still active burrows on your property, then it is important to fill them in properly with concrete or mortar and prevent further infestation.
9 Methods How to Fill Rodent Holes under Concrete
1. Use Expanding Foam.
If you have expanding foam on hand, this is a quick and easy way to fill rodent holes under concrete. Simply spray the foam into the hole, and it will expand to fill the space.
The downside of this method is that the foam can be difficult to remove if you ever need to access the space again. If you do use foam, make sure to cover any vents or other openings to prevent the foam from expanding into them.
2. Use Caulk.
Caulk is another quick and easy way to fill rodent holes under concrete. Simply apply the caulk to the hole, and it will harden in place, filling the space. The downside of this method is that it may not be as durable as other methods.

While caulk can last for several years, cement is much more durable. Additionally, if the caulk cracks or wears away over time, you may need to replace it, which is a much more difficult process than simply patching the hole with cement.
3. Use Hydraulic Cement.
Hydraulic cement is a type of cement that sets very quickly and can be used to fill rodent holes under concrete. Simply mix the hydraulic cement with water and then apply it to the hole.
It will set in just a few minutes, filling the space. The downside of this method is that it can be difficult to remove if you ever need to access the space again.
4. Use Epoxy Resin.
Epoxy resin is a strong and durable material that can be used to fill rodent holes under concrete. Simply mix the epoxy resin with a hardener and then apply it to the hole. It will set in just a few minutes, filling the space. The downside of this method is that it can be expensive.
5. Use Putty.
Putty is a pliable material that can be used to fill rodent holes under concrete. Simply apply the putty to the hole, and it will harden in place, filling the space.
The downside of this method is that it may not be as durable as other methods. It might need to be replaced or patched up sooner than other methods. Be sure to use a putty that is designed to be used for filling holes underneath the concrete. This will ensure that the putty can withstand the pressure and weight of the concrete above it.
6. Use Mortar Mix
Mortar mix is a type of concrete that sets very quickly and can be used to fill rodent holes under concrete. Simply mix the mortar mix with water and then apply it to the hole. You may need to use a trowel or putty knife to pack the mortar mix into the hole and ensure that it is completely filled.
7. Use Cement
One of the most common ways to fill rodent holes is with cement. Cement is a durable material that will effectively block off the hole and prevent rodents from entering your home.

To use cement, you will need to purchase a bag of ready-mixed concrete and mix it with water according to the instructions on the bag.
8. Use Plaster of Paris
Plaster of Paris is a type of plaster that can be used to fill rodent holes. Plaster of Paris dries hard and will effectively block off the hole and prevent rodents from entering your home.
To use this method, mix the plaster of Paris with water according to the instructions on the packaging. Fill up the hole with the mixture and let it dry for several hours. Once the plaster of Paris is fully dry and hardened, it will effectively seal off the hole and prevent rodents from entering your home.
9. Use Fiberglass Mesh
Fiberglass mesh can be used to fill rodent holes. Fiberglass mesh is a strong material that will effectively block off the hole and prevent rodents from entering your home.

It should be placed directly over the hole and secured with concrete. To ensure that the material is secure, you can use a drill to secure it into the concrete.
