How to Get Rid of Mice in Attic Under Insulation? Simple Strategies

Many people are afraid of mice, and having them in the attic can be really frustrating. This problem is usually persistent, especially when they find their way under the insulation. Besides the fear they cause, mice can make significant damage to insulation and wiring. Also, their presence poses health risks because they carry many diseases including hantavirus, leptospirosis, Salmonella etc.


This guide is written to walk you through different strategies to get rid of mice in your attic and keep them out for good.

How to Keep Mice Out of Insulation?


We all know that prevention is better than cure. Preventing mice from entering the attic is not complicated at all - you just need to seal all entry points. Inspect the attic for any gaps, cracks or holes in the walls, floors, and ceiling. Don’t be fooled - mice can get in even through the smallest openings, so seal all potential entry points.


The best materials to use are steel wool, caulk, and expandable foam - fill in the gaps and install weather stripping around doors and windows with them. Another good advice is to keep the attic clean and free of food sources. Store food in airtight containers and make sure all garbage bins have tight-fitting lids. Mice use materials like cardboard, paper and fabric for nesting, so regularly clean your attic to remove them. Long story short - maintain the cleanliness of your attic and you won’t have the reason to worry.


How to Get Rid of Mice in Attic with Blown Insulation?


To get rid of mice in attic with blown insulation, it might be necessary to remove and replace the affected insulating material. The removal process should be done carefully, with protective gear. Put the affected insulation parts in sealed bags for disposal, and replace them with new ones. New insulation should be less appealing to mice, such as cellulose or spray foam insulation. New attic insulation should be less appealing to mice, such as cellulose or spray foam insulation.


If there are any remaining mice in the attic, set up traps to catch them. The most effective options are snap traps, live traps and electronic traps. You need to place them near suspected entry points and areas with high mouse activity. Remember to check and empty the traps regularly, to maintain their effectiveness.


What Type of Insulation Keeps Mice Away?


Our advice is to opt for boric acid insulation or spray foam insulation. Boric acid-treated insulation is an excellent choice because it combines natural cellulose with borate pesticides, making it unappealing and potentially fatal to mice. Despite keeping mice away, this material is eco-friendly and offers fire-retardant properties.


Spray foam insulation is efficient because it creates a solid barrier that mice can’t chew through. Also, it seals small gaps and cracks, significantly reducing potential entry points for mice. Additionally, consider using reflective insulation rolls for added protection and energy efficiency.


What Insulation Do Mice Hate?


We can say that mice hate all previously mentioned materials due to their density and the difficulty in nesting with them. That is because these materials do not provide a food source for mice, so they do not find them attractive.


How to Get Rid of Mouse Urine Smell in Insulation?


Once you get rid of the mice, there is a urine smell that can continue to bother you. Here is what you need to do - after removing infested insulation, clean the entire area thoroughly. Our advice is to use a vacuum cleaner with HEPA filter to remove debris and droppings. Use a disinfectant spray to kill any remaining bacteria or viruses. You can do it with natural cleaning solutions like vinegar or hydrogen peroxide, too. Also, you should open all windows and use fans to improve air circulation in the attic. Good ventilation will reduce the smell over time.


Consider installing floor foil under your insulation to create a barrier against moisture and odors. Upgrading your house insulation with materials that are less attractive to pests can also help in maintaining a mice-free environment. When inspecting your home for potential entry points and damaged insulation, don't forget to check wall insulation as well, because mice can easily travel through walls and create nests.
