Polyurethane Foam Acts as a Barrier to Rodents

Preventing rodent intrusion with polyurethane injection

When it begins to get cold outside, mice and other rodents seek refuge. If they can find a way in, they’ll move into your house, creating huge problems for homeowners. They’ll eat or destroy your food, gnaw at your power cords, boxes and shoes, leave droppings all over your house and multiply quickly. Prevention is key, and polyurethane expanding foam is an inexpensive and effective option that could be part of the solution to a potentially big problem.


The key to deterring rodents from entering your home is to close, fill or cover any openings they may be using to gain entry. It’s best to inspect the areas around your home’s foundation from the outside for any cracks or gaps where rodents could get in. 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.

With polyurethane foam, the results are immediate. While it won’t get rid of infestations already in your home, it will prevent them from happening. When pumped, polyurethane expands to fill voids and cures in as little as 15 minutes.


From concrete leveling to void filling, polyurethane foam serves many purposes, including home pest control. Contact Mr. Level for more information on polyurethane foam or to get a free quote.
