If you’ve noticed signs of a mouse infestation in your home recently, you may be wondering if they can nest inside your wall or attic insulation. At Bay Area Rodent Solutions, we are experts when it comes to rodent behavior and capabilities. We have over 25 years of experience helping homeowners safely and effectively address mouse problems. Read on for answers to common questions about mice in insulation.
Do Mice Nest in Insulation?
Yes, mice often do build nests inside insulation inside walls or attics. Insulation provides an ideal nesting spot as it is soft, warm, and protected. Female mice looking for a place to raise their young will scope out cracks and voids filled with insulation as prime real estate. The insulating properties also help regulate temperatures which mice prefer for breeding.
How Can I Tell If Mice are Living in My Insulation?
Some signs that you may have mice nesting in insulation areas of your home include:
- Strange noises coming from inside walls – like scampering or squeaking
- Odd odors emanating from vents
- Evidence of mouse droppings around baseboards or ceiling corners
- Damaged insulation with chewed areas if you inspect your attic
- Seeing mice coming in and out of small holes or gaps leading to attic or walls
If you notice any of these signs, contact Bay Area Rodent Solutions right away for an inspection. We can insert inspection cameras into wall voids and attic spaces to check for mice activity and identify entry points. The sooner we can address an infestation, the better. 
How Do You Get Rid of Mice in Insulation?
Trying DIY removal tactics by placing traps or poison in your insulation rarely solves a mouse problem fully. This is because other mice can easily enter the same nesting space. For effective elimination, we recommend our full exclusion service:
- Inspection to find all possible mouse entry points into your home’s walls/attic
- Sealing up any exterior cracks, holes or openings with weather resistant materials
- Installing durable steel mesh barriers over areas mice may still gnaw through
- Setting up humane traps as needed to capture mice while exclusion work is underway
- Sanitizing the nesting areas once exclusion is complete
This multi-step process keeps new mice from getting back in while getting rid of current ones humanely. Rest assured our technicians take proper safety precautions when working in insulation areas. We guarantee our exclusions for at least one year and offer repair services if any new points of entry appear.
Frequently Asked Questions
What types of insulation do mice nest in?
Mice can nest in all types of building insulation – fiberglass batts, blown-in cellulose, rigid foam boards, and spray foam. Their powerful teeth allow them to chew through or spread apart most types of insulation to make room. Fiberglass insulation provides ideal nesting material.
Can insulation cause health issues if mice infest it?
Yes, mouse droppings and nesting materials left in insulation can cause health issues. Insulation particles may contain dried urine, viruses, bacteria, and allergens even after mice are removed. Contact a professional Insulation Cleaning Service before replacing insulation entirely to reduce risks.
Will I have to replace all my insulation if I had mice?
Not necessarily. If the infestation was minor and the insulation isn’t too soiled, we can treat it with sanitizing gels when doing the exclusion process. Moderate or heavy nesting may require partial or complete insulation replacement however. Bay Area Rodent Solutions can provide re-insulation services if needed.
What areas should be focused on to exclude mice?
Key areas our technicians focus on are: roof vents, foundation cracks, openings around utilities, gaps around flashing, attic gable vents, and dryer vents. All exterior entry points need to be mapped out and sealed up for successful exclusion.
How much does getting rid of mice in insulation cost?
Every home is different. After a thorough inspection, we provide a detailed proposal outlining the exclusion work recommended and associated costs. Many homeowners end up saving money in the long run by investing in high quality exclusion compared to short term fixes.
