How Long Does It Take To Get Rats Out of Your Walls?

It can take 3-7 days to get rats out of your walls. You may need the help of a professional to determine whether or not all the rats have died or left the area.

What’s worse, you will need to figure out if they have left food storage caches lying around in hidden areas. These foods may rot and attract many other pests like insects who will discover the caches and feed on them.

Rodent traps that are made with bait or mechanically produced are best handled by professionals when the discovery is made that your cavity wall has allowed these rodents to move in and nest inside your home.

How Do Rats Get in the Cavity Wall?

Rats get into cavity walls because they have found an opening and they have a strong insistence to find shelter for warmth and protection.

Rats are versatile and can fit into the tiniest holes or gaps. They can flatten their ribs and dislocate their skulls to make their way in when you thought it wasn’t possible.

Sealing involved using caulking, silicone, concrete and bait traps or mechanical traps to deter or prevent rats from getting into cavity walls. These places are perfect because we or other threats do not or cannot usually enter.

They can enter cavity walls from:

  • Chewed Plastic Air Bricks
  • Holes in Walls
  • Burrows Under the Walls
  • Drainage Faults

How Do I Get Rid of Rodents in My Wall Cavity?

Rodents that get in your wall cavity do so because they are seeking safety and shelter. They are successful and now it’s our turn to get them out. We may need an expert, but let’s review some tips and strategies to see what we can do first:

  • Prevention
  • Poisons and Traps
  • Get Help

Prevention

  1. Clear you property from surrounding vegetation and shrubs or logs that makes it easy for rats or other rodents to climb aboard and enter your home.
  2. Check for hollow areas and open entryways.
  3. Seal doorways, trash and packaging.
  4. Check plumbing and drains for openings or water leaks.

Poisons and Traps

It’s time to get aggressive. Lay out poison bait traps. The problem is that these wall cavities will make it hard for you to reach inside to lay the traps in areas where it is necessary.

Also, it will be very hard to remove the dead rats when you are successful in killing them with this poison. Catch and release traps are not for everyone.

Can you handle a screaming or squirming live rat in a mechanical trap or glue trap? I can’t and won’t.

Get Help

Maybe you have an experienced friend or relative to help you, but owing them a big favor in return should involve more than pizza or a drink. It is better if you think long-term and look at the big picture.

The entire property needs a thorough check. There could be nests and food caches all over the area and hidden so well that you cannot find them. A professional will inspect and help to clear the area while helping you seal entryways to make sure these pests do not return.
