Stop Attic Mice Permanently

If you have vinyl siding on your home you need to close the entrance door that mice use. You ask where is the door? Well, the door is at the bottom of the outside corners of your home. The corner piece is called the “corner post” and it is an open runway for mice to go directly into  our attic.

Take a small mirror and a flashlight and look up into each corner post on your house. You will see that there are no obstructions all the way up except for maybe a bee, wasp or hornet nest. This is how mice, rodents and insects get into your attic. This is why KritterCaps® were invented – to close this door.


You can trap or poison mice in the attic day in and day out and they will always keep coming back unless you stop them at the door. They can chew through foam and rodents can pull out mesh material and steel wool rusts and deteriorates. The KritterCap®Corner Insert” is a patented product that will permanently stop attic mice at the door.

The SCI–354 Corner Insert is designed to fit 3 inch 3 ½ inch and 4 inch corner posts. It fits up inside the corner post and does not require any screws, caulk, foam or glue to hold it in place. It does not contain poison or sticky glues, there are no springs and it  doesn’t require a power source for it to work 24/7.

It installs in minutes and, when properly installed, it will not fall out nor will it deteriorate over time. It lets the corner post breathe so there is no chance of rotting the sill plate, due to condensation, and causing an infestation of carpenter ants. It prevents chipmunks from hiding from dogs and predators which chase them into the corner post. And as an added bonus, in the north, it helps prevent cold winter drafts in the corner of the home.


RIDGE VENT ENDCAPS™ seal off the ends of open ridge vents putting a stop to mice, rats and bats entering the attic through the open end.  Check out the details!

This photo shows the gap that is created when the home builder does not overlap one end of the plywood sheathing to give a square corner. This gap can be 1 or 2 inches in length. These are the gaps that the Inside Filler Tabs on the SCI-354 Corner Insert close off and prevent mice from going up the inside of the corner post.
