How To Stop Animals From Digging Holes Around Your Foundation

Are you bothered by strange digging noises coming from beneath your floors? Did you wake up one morning to see holes in your foundation? Do you constantly see chunks of grass around your area even though you have cleaned them already? These factors show possibilities that a certain animal is trying to make a nest below your house. 

Animals that keep digging out your foundation really cause nuisance and inconvenience. This is why you have to act on it immediately before they completely make a massive mess out of your foundation. 

This article will give you tips on how to spot intruders and will go into preventing animals from digging holes around your foundation.

How To Stop Animals From Digging Holes Around Your Foundation

  1. Your initial step is to remove or eliminate the pests. Mice trap a good way to go. However, if you have larger pests like squirrels, rats, or skunks, contacting the exterminators would be best because these rodents carry diseases that can be fatal to humans. Therefore, such work must be left to professionals. 
  2. Fill in the existing holes. Any holes that have been created by pests must be closed or filled in, in order to keep any animals out. They won’t be able to nest in your foundation if you have their entry points sealed. Do this by sealing off the open vents, repairing or filling the cracks, and replacing damaged vapor barriers. 
  3. Invest in well-researched and safe chemical products. Although there are many chemical items on the market that will surely kill these pesky animals, it would be better to opt for the safe ones. I’m talking about products that have offensive scents, enough to drive the diggers away. That way, you’re sure that friendly animals won’t be affected that much. 
  4. Make your home critter-free by sealing off trash cans tightly with their lids. If you feed birds, regularly clean the debris around their feeders. If you have pet food, keep them in airtight containers to prevent pests from being attracted to food scents.
  5. Trim back obscuring bushes. Doing so will prevent animals from remaining hidden. It will then be easier for you to mitigate any problems in the area. 
  6. Seclude the area. After your area has been cleared from pests, screen your place, add cement and add patio blocks. This will assure you that nothing will ever come digging beneath your house again. 
  7. Install barriers. Chicken wire or chain link fence may also be helpful in keeping the animals out.

We are confident that these steps will help to minimize the damage caused by digging animals.

Also, these tips are the most humane options. Because no matter how pesky these animals are, they are just trying to survive like you and I.
