Seasonality, habitat and survival

Morris County has a lot of post-1960s suburban construction alongside historic town centers like Morristown and Chatham, and includes several borough/township pairs (Boonton Town vs. Boonton Township, Chatham Borough vs. Chatham Township) — construction era matters more here than in denser counties, since newer builds tend to have different vent and soffit designs than the historic downtown cores.

New Jersey bat exclusion timing: per NJ Division of Fish & Wildlife guidelines, bat exclusion is not permitted May 1 – July 31 while maternity colonies have flightless pups in the roost. The state’s safe windows for exclusion are April 1 – 30 and August 1 – October 15; work is also limited October 16 – March 31 when bats may be overwintering in a structure. We plan every Morris County exclusion around these dates unless there’s an imminent health/safety exception.

If human or pet contact is suspected, contact local health guidance immediately.

4-step process

Inspect: Entry mapping and attic/roof survey.
Plan: Time-appropriate exclusion strategy.
Exclude: Install one-way devices and seal gaps.
Restore: Cleanup and prevention plan.

Bat Proofing & Sealing — Riverdale, NJ

Bat proofing is the actual fix: one-way devices at active openings, then permanent sealing of every access point on your Riverdale home once bats are confirmed out.

How Proofing Actually Works

Every confirmed and suspected entry point gets a one-way device or is directly sealed, depending on whether it’s currently active. Active openings get the one-way valve first — it lets bats leave but not re-enter — and stay in place until we’ve confirmed the roost is fully vacated. Only then does that opening get permanently closed with materials matched to the building (galvanized mesh, sealant, flashing repair, or trim replacement, depending on the gap).

Proofing a Riverdale home also means checking the seams that aren’t obviously openings yet — where siding meets trim, where additions meet original construction — since those are exactly where new gaps tend to form over time.

Frequently Asked Questions

What is a one-way bat exclusion device?

A device that lets bats exit an active opening but blocks re-entry, until the opening is permanently sealed.

Does proofing mean sealing every hole in the house?

No — it targets actual and potential bat-access points while respecting necessary ventilation and structural requirements.

Will sealing stop bats permanently?

Proper exclusion with durable repairs significantly reduces re-entry, though buildings can develop new gaps over time.

Should I seal holes as soon as I see bats leave?

No — sealing too early can trap bats inside. Devices confirm the roost is empty first.

What materials are used for sealing?

It depends on the gap — galvanized mesh, sealant, flashing repair, or trim replacement matched to the building.

How long do one-way devices stay up?

Until the roost is confirmed vacated, which can take anywhere from several days to a couple weeks depending on activity.
