While spray foam insulation is great for sealing off these areas and may be a temporary solution for keeping rats and mice out of residential buildings, the material is not rodent-proof. Professionals such as the rodent proofing team from Attic Construction will use only high-grade materials to keep the pests out.
Rodents are most drawn to fiberglass insulation, but any variety works well for their needs. They tunnel through the material and gnaw at it for food or to make a nest. And all the while they will leave their urine and droppings, and these contaminants will stay behind long after the rodents are gone.
Cellulose Insulation
The experts also mix some types of chemicals into the insulation to make it fire resistant. Cellulose insulation is popular to prevent insects and bugs from entering the house because of the boric acid which is used in it. This chemical is also known as hydrogen borate.
RODENT-RESISTANT EXPANDING FOAM
Rodents can also squeeze through gaps and openings in pipes, so you'll want to seal around those, as well. Filling the cracks and voids with the polyurethane foam acts as a rodent barrier, as mice and other rodents aren't able to chew through spray foam insulation.
Mice have been known to chew through electrical wires, fiberglass insulation batts, and rigid foam insulation. Worst-case scenario, evidence of mice (in any part of a house) can cause problems when its time to sell the place. The best is to stop mice from even entering.

When compared with other insulation products, spray foam insulation offers the highest R-Value per installed inch. Because spray foam will completely seal and insulate the “building envelope”,, allowing for the ultimate in thermal protection (and R-Value). Spray foam can be closed-cell or open-cell.
As it turns out, there are several smells that these pests cannot stand, which means you can use them to your advantage. But what exactly do mice and rats hate to smell? Mice can be kept away by using the smells of peppermint oil, cinnamon, vinegar, citronella, ammonia, bleach, and mothballs.
A great way of accomplishing this is to make a barrier out of mesh wiring that will surround the foam insulation. By doing this, the mice won't be able to make their way past the mesh wiring, stopping them from destroying your foam insulation.
Fill Up Holes With Steel Wool
Unlike insulation, paper, or even drywall, mice can't chew through steel wool, and even if they did, they'd be dead before they made it into your pantry. Stuff any holes where mice could be entering with steel wool and you'll keep them from sneaking in.
Seal up gaps and holes inside and outside your home
Seal any holes you find to stop rodents from entering. Fill small holes with steel wool. Put caulk around the steel wool to keep it in place or use spray foam. Use lath screen or lath metal, cement, hardware cloth, or metal sheeting to fix larger holes.
Here are some ways to prevent mice from getting in and making a home in your walls: Seal cracks in your foundation and walls. Avoid using plastic, rubber, or wood as sealant, as mice can gnaw through these materials. Instead, use wire/stainless steel mesh or quick-drying cement.
Can mice chew through steel wool? Yes, but they choose not to in most instances because a steel wool bundle has sharp edges that are abrasive to their nose. The problem is, oftentimes, they will grab the bundle with their feet and pull it out of a sealed opening. Cause for concern.

They won't move out of your home at any time of year unless you throw them out with the help of pest control professionals. If you spot a mouse or any other rodent in your home, do not wait any minute.
Just because the weather is warming up and mice will soon discover that temperatures are pleasant outside, does not mean that they will move out. The reality is that mice, like most other household pests, are in search of food, water, and shelter. This alone makes these nasty rodents a year-round pest.
If the conditions are not favourable, they will likely return to where they came from. But this will not necessarily deter mice from returning to gather more foodstuff or nesting materials.
Unfortunately, mice enjoy the warmth of your clothes dryer just as much as you do. For rodents looking for a warm place to wait out the cold, a dryer vent is one of the easiest ways to get inside your cozy home.
Mice know cats are in your home because they can smell their predators. The mere whiff of cat urine and litter is often enough to scare the mice away.
A mouse can get through a small, 6-7 mm hole (about the diameter of a normal-sized pen) and a rat can get through a 20 mm hole. They can also jump several decimetres at a time.
