June is one of the busiest months for wildlife activity in Michigan as raccoons, squirrels, birds, and bats search for safe places to raise their young. Homes often provide ideal shelter, leading to property damage, contamination, insulation destruction, and costly repairs if issues go unnoticed. Early inspection, humane exclusion, and proactive repairs can help prevent minor wildlife intrusions from becoming major restoration projects.
June has a way of lulling Michigan homeowners into a false sense of calm. The snow is gone, the roof made it through another winter, and the worst of spring storm season seems to be behind us. It feels like a good time to take a breath before summer really gets going.
But while you're enjoying the warmer weather, something else is happening. Across Oakland and Macomb County, raccoons are raising their young. Squirrels are on their second litter cycle. Bats are nursing pups in the dark corners of attics. And all of these animals are looking for the same thing: a safe, dry, sheltered space to raise their families. For a lot of them, that space is your home.
We've seen it play out the same way dozens of times. A homeowner hears a scratching sound at night, figures it's probably just squirrels on the roof, and decides to wait it out. A few weeks later, they find torn insulation, compromised wiring, or a spreading stain on the ceiling. By that point, what started as an entry point issue has turned into a full-scale cleanup and restoration job. June is not the month to take a wait-and-see approach.
Raccoons are the most destructive wildlife threat to Michigan homes, and June is when that threat is at its highest. A mother raccoon with kits is not going to be deterred by noise or minor obstacles. She will tear through roof edges, rip back soffit panels, and push through damaged fascia boards to get to a space that feels secure.
Common raccoon nesting spots include:
Raccoon baby season also complicates removal. If a mother is excluded before the kits can move on their own, the young are left behind, and the resulting situation is far more difficult to resolve.
Squirrels are quieter than raccoons but no less damaging over time. They chew constantly, not because they're hungry, but because their teeth never stop growing. That means wiring, insulation, and wooden structural members are all fair targets once a squirrel has established a nest in your attic.
Watch for:
June's second litter cycle keeps squirrel activity elevated well into late summer, so this is not a problem that naturally resolves on its own.
Starlings and house sparrows are the two species homeowners deal with most often in Michigan. Both are non-native, highly adaptable, and drawn to the same structural gaps that attract other wildlife. They pack nesting material into dryer vents, bathroom exhaust vents, and chimney flues, creating blockages that are both a health risk and a fire hazard.
If you've noticed reduced airflow from an exhaust vent or an unusual smell coming from your fireplace, it's worth having it checked. Bird nests inside ventilation systems are more common than most homeowners expect.
Bats are a special case, and they require careful handling. Michigan is home to several bat species, and a number of them are protected under state and federal wildlife regulations. June falls squarely within the maternity season, meaning bat pups have been born but cannot yet fly. Exclusion work during this window is restricted by law in many situations, because sealing an entry point with pups inside can trap and kill them.
Common bat entry points include:
If you suspect bats, document what you're seeing and call a professional before doing anything else. The timing of exclusion work matters legally and practically.
This is where a lot of DIY attempts run into serious problems. Wildlife removal and exclusion isn't just about getting the animal out. It's about making sure every animal is out, understanding whether young are present, complying with Michigan wildlife regulations, and then sealing the home in a way that actually holds.
A few things that matter here:
Once the animals are out and the entry points are properly sealed and repaired, the goal shifts to making sure June doesn't become a recurring problem. A few practical steps make a significant difference:
Most homeowners don't call us the moment they hear the first sound. They wait a few days to see if it goes away. They look up how to handle it themselves. They wonder if maybe it was just something on the roof. We understand that instinct. Nobody wants to deal with a wildlife problem.
But wildlife damage compounds fast. What starts as one animal using one entry point can become an established colony within weeks. The insulation that was in good shape when the season started gets torn apart. The wiring that was fine gets chewed. The moisture from nesting materials starts to work into the wood. And then the mold finds its footing.

Squirrels in an attic can cause far more damage than most homeowners realize, including compromised roof vents, rotted fascia boards, damaged insulation, and chewed electrical wiring. Because wiring damage is often hidden, it can create a serious fire hazard long before any visible warning signs appear. Early inspection and professional repairs can help prevent costly structural damage and reduce safety risks.
Raccoons can cause extensive attic damage by destroying insulation, contaminating materials with waste, damaging vents, and chewing electrical wiring. What may start as occasional noises overhead can quickly develop into a costly restoration project if left unaddressed. Early inspection and professional remediation help protect a home's structure, energy efficiency, safety, and indoor environment.
Possums living in crawlspaces can cause far more than nuisance wildlife problems by damaging vapor barriers, contaminating insulation, and creating conditions that promote mold growth. Once moisture levels rise beneath a home, structural materials, indoor air quality, and energy efficiency can all be affected. Professional cleanup, mold remediation, vapor barrier replacement, and exclusion services are often necessary to fully resolve the issue and prevent future damage.
