How to get rid of mice

There is nothing worse than noticing rat or mice droppings in your home, particularly in the kitchen.  Rats and mice have collapsible skeletons that allow them to fit through small spaces so making your house harder to penetrate will cure the problem for good.  So, how to get rid of mice?

Once they find a way inside your home they look for somewhere warm.  You may notice droppings in the following areas:

  • Behind the fridge.
  • Inside the boiler.
  • Under the tumble dryer.
  • Food cupboards.

The only way to be rid of them properly is to block their access from the OUTSIDE first.

If you block access and starve them, they will die out.  It’s that simple.  You can seek advice or engage the services of a professional exterminator but why waste money when the guide will work.

Follow our guide:

  1. Cover the air bricks around your property without blocking much-needed air to enter under the floor (see picture below).
  2. Buy a sheet of aluminium radiator cover.
  3. Measure the size of the air brick you want to cover.
  4. Carefully cut the aluminium radiator to the measurements you have taken using tin snips (cutters).
  5. Using clear mastic (sealant) and an applicator gun (for instructions click here), apply the sealant around the edges of the shape you have cut.
  6. Place the shape you have cut over the air brick and hold it in place for one minute.
  7. Now repeat the same process and cover all the air bricks around your property.  If you are not confident to do this yourself, click here to find a contractor to help you.
  8. Seal all the cracks and holes behind sinks and around pipes in the kitchen and throughout the property using resin bond and an applicator gun (for instructions click here).  You can use expanding foam but rodents tend to pick through it.
  9. Now you need to starve them:
      1. Clean dirty dishes after your meals, never leave dirty dishes out all night.
      2. Wipe surfaces after spills, cooking and eating.
      3. Keep food sealed and stored in cupboards.
      4. Keep your house tidy, pests love clutter.
      5. Keep floors swept and clear of leftover crumbs and food.
      6. Keep floors clear of pet food, never leave pet food in bowls overnight.
      7. Purchase a Brabantia bin with a closed lid and empty it often (we have had ours since 2006 and it is still in perfect working order).

You can purchase mouse traps but if you have blocked their access and starved them, you will not need to use these.

Once starved you may never find the expired rodent(s) in your property afterwards but if you do, dispose of them carefully.  Never touch them with your bare hands, use gloves and dispose of them by burying them or place them in a sealed bag and place them in the bin.

Air brick covered with a cut to size aluminium radiator cover and clear mastic (below).  As you can see the holes are now much smaller in the air brick which directly prevents mice from being able to gain access to your home.  This method was used in our house and many years later it still looks the same (no rust and no mice!)  This is the key ingredient on how to get rid of mice for good in your property.
