One-Way Doors and Ridge Guards: How Flying Squirrel Exclusion Actually Works
Homeowners in Waterbury and Middlebury often ask why ProSource does not simply trap the flying squirrels in their attic and take them away. The short answer is that trapping does not solve a flying squirrel problem. Colonies are large, the animals are small enough to slip through gaps the width of a thumb, and new squirrels will find the same openings next season. The method that works is exclusion: letting the animals out through one-way doors and sealing every entry point so they cannot return.
How One-Way Doors Work
A one-way door is a lightweight hinged or spring-loaded device mounted over the main entry hole. Flying squirrels push through it when they leave the attic at dusk to feed, but it closes behind them and they cannot get back in. Within days, the colony is outside and the attic is empty. No animal is harmed, no trap needs to be checked, and nothing dies inside your walls.
Why Ridge Guards Matter in Connecticut Homes
Many Connecticut homes have ridge vents running along the roof peak. The vent material itself is thin, and flying squirrels chew through it easily or squeeze beneath its edges. A ridge guard is a heavy-gauge metal barrier installed over the ridge vent that keeps airflow intact while blocking animal entry. On a recent Middlebury exclusion, ridge guard installation was the first step, followed by sealing secondary gaps and installing the one-way doors.
The Full Exclusion Timeline
A typical ProSource flying squirrel exclusion follows a clear sequence. First, a thorough inspection maps every entry point along the roofline, soffits, gable vents, and chimney. Second, secondary openings are sealed and ridge guards installed, leaving only the main entry open. Third, one-way doors go on the main entry. One to three weeks later, a technician returns, confirms the attic is quiet, removes the doors, seals the final opening, and completes a final inspection.
What Happens After Exclusion
Once the structure is sealed, the attic may need attention. Months of colony activity leave droppings and contaminated insulation behind. Our guide to attic decontamination after wildlife explains when cleanup is necessary, and many homeowners take the opportunity to upgrade to TAP pest control insulation.
Frequently Asked Questions
Can you trap flying squirrels instead of using exclusion?
Trapping is not an effective solution for flying squirrels. Colonies are too large to remove one at a time, and the open entry points invite new animals. Exclusion with one-way doors removes the entire colony and permanently seals the home, which is why ProSource uses it for every flying squirrel job.
How long does flying squirrel exclusion take?
Most exclusions take one to three weeks from the first visit to the final seal. The initial sealing and door installation happen on day one; the return visit to remove the doors is scheduled once the attic has been quiet for several nights.
Will flying squirrels die inside the attic?
No. One-way doors allow every animal to leave on its own schedule. That is a key reason ProSource does not seal a home completely until the colony has exited. Sealing too early traps animals inside and causes odor and damage.
Do ridge guards block attic ventilation?
No. Ridge guards are designed to sit over the existing ridge vent and preserve airflow while blocking squirrels, bats, and other wildlife. They are a standard part of exclusion on Connecticut homes with ridge-vented roofs.
Is flying squirrel exclusion guaranteed?
ProSource exclusion work includes warranty coverage with annual renewal options so the home stays protected season after season. Details are provided with your written inspection report.
