  • Warmth & Safety – Rodents look for a warm and safe place to hide. They can easily find such a space inside our homes. They can hide inside walls, attics, basements, garage, under the floorboards, or neat a hot water tank.


  • Food & Water – Mice and rats enjoy a lot of things such as cheese, chocolates, peanut butter or anything that they find. They are always on the lookout for food and our homes are full of such things. Especially when we have kids and pets, there is food around.

How to Mouse Proof Your House?

Mice and rats find ways to enter homes through tiniest holes and cracks. Therefore, it is challenging to mouse-proof your entire house. It is not impossible though. The key to preventing mice from coming inside is to mouse proof your home. And, here’s how you can do this:

  • Inspect Foundation – Check the foundation all the way around the home as it’s the easiest way for rodents to enter. They can enter from any crack or hole that is ½” or larger. You need to repair any such crack or hole using sheet metal or hardware cloth.


  • Check Door & Window Frames – Carefully check all the door and window frames for any weather stripping. Make sure that all frames create a tight seal and if not, get them repaired. Rodents can easily enter from the gaps that do not create a tight seal.


  • Inspect the Roof – Check everything starting from roof ventilators and shingles to vent screens. Make sure everything is secure and undamaged because roof rats often enter from such places. Also, make sure the chimney is properly capped.


  • Check Trees and Hedges – Make sure that there is no space for rodents to enter via nearby trees or branches. Rats and mice are good climbers and can use the tress as their pathways to enter your house. Cut any branches that touch or hang over your house.


  • Check Pipes – Make sure that pipes that run through your house are properly maintained and sealed. As rodents can climb through the pipes, it will be better to paint a band around the pipe using high gloss clear paint.


  • Remove Easy Food Sources – Access to food is the main motive of rodents and they often infest houses with open food sources. So, remove food and water sources and keep everything in airtight containers. Use appropriate animal feeders to keep mice away.


  • Clean Spills & Appliances – Make it a habit to regularly clean under stoves, storage boxes, and refrigerators. Also, clean the countertops and floors for any spills that may attract rodents.


  • Seal Holes – Check for any exterior holes and seal them immediately. These holes are often found in outdoor walls basically made for cables and pipes. Seal any holes that are larger than 5mm as mice quickly gnaw such openings to enter a building.


  • Use Natural Repellents – If you think your house is already infested by rats or mice use products that naturally repel rodents. You can use peppermint, clove oil, baking soda, onions oil, etc.


  • Brick Weep Holes – These bricks are designed specifically for weep holes to keep mice away. They form a perfect fit and flexible enough that you can easily push them between the bricks.


  • Use Traps – If you’re not satisfied by other methods or want to completely satisfy that there are no rats, use traps. You can easily get reusable traps from a reputed online store and try to get one that does not harm animals.


What are Weep Hole Covers?

We just mentioned brick weep holes, but what’s this? Weep holes are small gaps between the bricks especially in the lower part of the wall. The main purpose of these weep gaps is for drainage and ventilation. These holes prevent moisture damage and important for the structural integrity of any brick house. However, these holes can be used by rodents such as mice and rats to enter our homes.

So, if these holes are so important, then what’s the solution? You can use a plastic or metal mesh but neither works out well. The perfect solution is using weep hole covers as they are designed just for weep holes. You just have to pinch the sides together and push the piece in. It will automatically expand back to the proper size. Isn’t it an easy breeze?
