If you’ve never had bat removal done before, the process can seem mysterious. What exactly happens when we show up? How long does it take? What does your attic look like when we’re done? This guide walks through exactly what professional bat attic removal looks like in a typical Utah home.
Step 1: The Free Inspection (Day 1)
Our licensed technician arrives at your property and performs a comprehensive inspection that includes:
- Exterior roofline walk-around: We examine every potential bat entry point — gable vents, ridge cap, soffit gaps, fascia boards, chimney junctions, utility penetrations, and anywhere else bats might enter a structure at your roofline height
- Attic interior assessment: We enter the attic to assess colony size (looking at guano accumulation patterns, staining, and active areas), identify the primary roost cluster location, and note the extent of any contamination
- Species identification: We identify what bat species are present — important for compliance and for sizing the exclusion work correctly
- Written report and estimate: You receive a detailed written estimate before any work begins — no surprises
Time: 30–90 minutes depending on property size
Step 2: Exclusion Device Installation (Service Day 1)
On the first service day, our crew:
- Installs one-way exclusion devices (also called exclusion tubes or cones) over all active bat entry points — the ones where bats are currently entering and exiting
- Seals or screens all inactive secondary entry points that bats aren’t currently using but could exploit if primary entries are closed
- Does NOT seal the active primary entries yet — that happens after all bats have exited
One-way exclusion devices allow bats to exit normally (they push through the device on their way out to feed at dusk) but physically prevent them from re-entering. The device creates a one-way door: out only.
Time: 2–6 hours depending on entry points
Step 3: Monitoring Period (Days 2–7)
After exclusion devices are installed, we allow 3–7 days for the full colony to exit. Every bat in the colony exits nightly to feed — by the end of this period, all bats have passed through the exclusion device and are unable to return.
During this period you may notice:
- Bats crawling around the exclusion device in the evening, looking confused — this is normal and expected
- Decreased sounds from the attic as the colony disperses
- Bats roosting temporarily on the exterior of the home near the exclusion site
You do not need to be home during this monitoring period.
Step 4: Final Sealing (Service Day 2)
We return after the monitoring period to:
- Remove all exclusion devices
- Permanently seal every entry point we identified, including all primary and secondary entries, using materials appropriate for your construction type and Utah’s climate
- Perform a final exterior inspection to confirm all gaps are sealed and no bats are present
- Provide you with a written warranty documenting our work and your coverage
Time: 1–4 hours depending on entry points
Optional Step 5: Guano Cleanup (Scheduled Separately)
If significant guano accumulation was found during inspection, we schedule a separate cleanup service. This is recommended for any colony that was active for more than one season. The cleanup is typically scheduled 1–2 weeks after final sealing to ensure the structure is completely bat-free before crew enters.
