While most people enjoy watching these bushy tailed rodents scamper through local parks or dash across power lines, the reality changes quickly when they decide your attic is their new maternity ward. In our region, the two species our team most commonly deals withs are eastern gray squirrels and fox squirrels. These creatures are remarkably adapted for climbing, which makes your roofline a primary target for their explorations. They possess incredibly strong teeth that grow throughout their lives, requiring them to gnaw on hard materials to keep those incisors at a manageable length. When they find a small gap in your fascia boards or a loose vent, they use those teeth like chisels to create an entrance large enough for their bodies.
Ground Squirrels
While tree squirrels are the most common attic invaders, ground squirrels create a different but equally serious threat for property owners. Instead of nesting above ceilings and insulation, they focus their activity underground, carving out large burrow systems beneath sheds, patios, decks, foundations, and even concrete slabs. These tunnels can extend several feet in multiple directions and often include more than one entrance, allowing them to move quickly between feeding areas and shelter without being easily detected.
As their digging continues, the soil around structures begins to lose the support it needs to stay stable. That slow erosion and displacement can cause walkways to sink, pavers to shift, and slabs to settle unevenly. In many cases, the first visible warning signs are cracked concrete, tilted stepping stones, or gaps forming along the edges of patios and foundations. Over time, repeated burrowing in the same area can weaken the ground enough to contribute to long-term structural issues, especially in areas with heavy rainfall, loose soil, or frequent irrigation.
Ground squirrels are also notorious for targeting irrigation lines and underground utility pathways. They naturally follow the softer, disturbed soil around pipes and conduits because it is easier to dig through, and once they find these routes, they often keep expanding their tunnels along them. Their constant chewing can puncture water lines, leading to leaks that soak the surrounding soil and accelerate settling. Even worse, damage to buried electrical or communication cables may not be discovered until systems fail, creating sudden repair costs that can be far higher than the original wildlife issue. Because these problems develop out of sight, ground squirrel activity often goes unnoticed until the damage is advanced and the repairs become extensive.
Potential Structural Hazards And Mechanical Damage
The primary concern with a squirrel infestation is not just the noise, though the scratching and scampering at four in the morning is certainly enough to drive anyone to frustration. The true danger lies in what you cannot see behind the walls. Because these rodents are motivated by a biological need to chew, they often target electrical wiring. The plastic insulation around your wires is apparently quite satisfying for them to gnaw on, which creates a significant fire hazard as exposed copper wires can spark or overheat near dry nesting materials.
The integrity of your roof is also at risk when these animals move in. They often exploit areas where different roof lines meet or where the shingles are slightly lifted. Once they gain a foothold, they will expand the hole, allowing rainwater to seep into your attic. This moisture leads to wood rot and mold growth, which can be far more expensive to repair than the initial hole itself. Furthermore, the insulation in your attic serves a vital purpose for your home's energy efficiency. When squirrels inhabit the space, they compress the material with their weight and contaminate it with urine and droppings. This reduces the R-value of the insulation, making your heating and cooling systems work harder, eventually showing up as an increase on your monthly utility bills.
Our Removal Strategies And Exclusion Techniques
Managing a squirrel problem requires a strategic approach that goes beyond simple trapping. It starts with a comprehensive inspection of the entire perimeter of the building. Our professionals look for every possible entry point, which can be as small as a golf ball. These animals are flexible and can squeeze through surprisingly tight spaces. Once we identify the primary holes and any potential secondary entries, we implement a plan to remove the occupants.
Our professionals make use of specialized devices, such as one-way doors, that are designed to humanely allow the squirrels to leave the structure to forage for food as they would have anyway. The measures we install, however, prevent them from regaining entry when they try to make their way back to their hiding spot. This method is particularly effective because it uses the animal's natural daily patterns to clear the structure of intruders without causing unnecessary damage to the property or stress to the creatures.
Exclusion is the most critical phase of our service. Simply removing the current intruders does little to solve the long-term issue if the holes remain open. Other squirrels in the neighborhood will quickly pick up the scent of the previous occupants and try to move in. We use high-grade materials that are designed to withstand the elements and the persistent gnawing of rodents. Our goal is to create a durable barrier that restores the security of your home’s perimeter. This process requires a keen eye for detail and an understanding of how these animals move.
Sanitization And Restoring The Interior Environment
After the squirrels are gone and the house is sealed, the final stage involves cleaning up the mess they left behind. An attic that has hosted a family of squirrels is often a biological hazard. The accumulation of waste can harbor parasites like fleas, ticks, and mites, which may migrate into the living areas of your home once their primary hosts are gone. Additionally, the pheromones left in the urine can attract more wildlife to the area for years to come.
In cases of severe infestation, we also offer guidance on insulation restoration. If the material is heavily soiled or compressed, it may need to be removed and replaced to ensure your home remains energy efficient and healthy. This isn't just a matter of aesthetics; it is about the air quality of your entire household. Air from the attic frequently circulates into the lower levels of a home through gaps in the ceiling and around light fixtures. By cleaning and restoring the space, we help protect the health of your family and the longevity of your property
Managing wildlife issues requires a balance of technical skill and local knowledge of how Iowa pests behave during the changing seasons.

Frequently Asked Questions About Squirrels
Q1. Why Do Squirrels Choose Attics Instead Of Staying Outdoors?
A1. Attics provide exactly what squirrels look for when raising young or escaping harsh weather. The space is warm, dry, elevated from predators, and rarely disturbed. Once a squirrel discovers a weak spot near the roof, it treats the structure like a hollow tree. If access points are not reinforced, the attic becomes a reliable shelter that can be reused year after year.
Q2. Can A Squirrel Problem Really Increase Utility Costs?
A2. Yes, and it often happens without homeowners realizing why. Squirrels trample insulation as they move and build nests, which reduces its ability to regulate indoor temperatures. Contamination from waste also breaks down insulation performance. As a result, heating and cooling systems must work harder to maintain comfort, leading to higher monthly energy bills.
Q3. Why Is Sealing Entry Points More Important Than Removal Alone?
A3. Removing squirrels without closing access points only solves the problem temporarily. Other animals can detect lingering scents and quickly take advantage of the same openings. Professional exclusion focuses on reinforcing vulnerable areas with durable materials that resist chewing and weather exposure. This prevents repeat invasions and protects the structure long after the original animals are gone.
