How to Protect Your House From Mice

Mice are small but incredibly smart rodents that can quickly become a huge problem if they get into your house one way or another. Read our detailed guide to learn how to protect your household from these pests all year round. 

1. Seal Any Cracks And Crevices

Even the tiniest cracks and crevices in your house can serve as entryways for mice. Did you know that they can squeeze themselves into any holes that are a quarter of their body size? For this reason, you have to inspect your entire house thoroughly to detect and then seal any potential entryways. Here is a checklist you should follow:

  • Inspect exterior walls for cracks and holes
  • Look for cracks and gaps around doors and windows
  • Check out the areas around pipes, drains, and vents for gaps
  • Make sure that the chimney is in good condition and capped properly

Once you find and mark all the spots that have to be sealed, use rodent-proofing materials to seal them. Here are the best solutions:

  • 19-gauge or heavier hardware cloth
  • 24-gauge or thicker perforated metal patches
  • 26-gauge or thicker galvanized metal
  • 1:3 cement mortar
  • Steel wool

2. Use Mice Repellents

Although sealing your house is already a very effective measure, but you may also want to keep the mice at bay by using an effective repellant. The most effective remedies for repelling mice include:

  • Peppermint oil repellant sprays – mice hate the smell of peppermint oil and avoid wandering around in regularly treated areas
  • Ultrasonic repellents – this tech remedy repels mice by making ultrasonic warning noise. Use it together with chemical remedies for the best effect
  • Scented pouches – this remedy is very convenient to apply and reapply as you don’t have to spray anything and can simply replace old pouches. It’s also a non-chemical way that is not dangerous for pets

3. Eliminate Rodent Habitats

Mice usually inhabit neglected places, such as piles of debris, basement and attic clutter, piles of old building materials, and firewood storage. What you need to do is relocate fire storage to a spot at least 10-20 feet away from your house because it’s usually a place where mice are present all year round to feed spiders and slugs. Next, take a while to find and dispose of all the neglected piles of debris to make your yard, basement, attic, and garage less attractive for rodents.

4. Remove Food And Water Sources

Once you deal with mice habitats, you should also inspect your house and yard for food and water sources. It may happen that there are problems with water flow in the gutter system, or there are paddles near the house. Another common source of food for mice is a bird feeder. Birds are careful when they eat and throw a lot of seeds down, which quickly attracts mice and even rats from all around the neighborhood. There’s no need to remove the feeder, but you should replace it with a tree that’s at least 20 feet away from the house. It’s also recommended to use rodent-proof feeders that are impossible to climb on. 

Next, you should pay attention to the outdoor trash cans. Rodents can quite easily squeeze through rusty holes in cans or even lift up the lids to get in and feed. You have to seal any holes if you find them and put something heavy upon the lids to make them impenetrable. You can also order new trash cans with locks or pull bungee cords to hold them tight. 

Finally, if you have dogs and cats that are allowed to go outside, you have to avoid leaving their food outside as its smell can attract mice from far away. It’s not prohibited to feed them outside at all, but you should remove the feeders every time your pets finish eating. 

5. Trim The Trees And Shrubs

Trim The Trees And Shrubs

Mice and rats have an incredible sense of balance and sharp claws, which lets them climb almost anywhere they want. Besides, they can jump up to 4 feet long to access hard-to-reach places. This being said, you have to inspect all the trees and shrubs around the house and trim any branches that overhang the house or make it possible for the mice to jump from. You have to repeat this every year. Otherwise, the mice will definitely find a way to your attic, especially if it’s not sealed properly. 

6. Employ Bait Stations

If you live in an area that’s more prone to rodent infestations than others, such as a city or a neighborhood that’s close to the woods, you can control the rodent population using poisonous baits. The infestations in such areas usually occur in fall and winter as the mice seek warmer places to live in. Your mission is to place poisonous baits near potential entry holes and places that are not accessible to your pets. This will kill rodents that come to your house perimeter in search of the new dwelling and give a signal to others that there’s nothing to look for. 

7. Extra Tips

Here is a list of tips that will help you additionally protect your house from mice:

  • Fix damaged door and window screens
  • Install automatic door enclosure mechanisms to avoid forgetting to close the doors
  • Dispose of garbage regularly
  • Screen vents and the chimney entry
  • Keep all the areas of your house well-ventilated
  • Unclog drains and fix leaking pipes in the basement

8. Seek Professional Help
