Bat Control
Inspection-led bat control and exclusion planning for structures with suspected roosting activity.
Bats may roost in attics, roof gaps, vents, and other protected parts of a structure. Because the correct response depends on the entry points, roost location, and timing, Cragoe begins with a careful inspection.
What to look for
Sounds near dusk or dawn
Scratching, rustling, or movement from an attic or wall area may be noticed when bats leave or return.
Visible entry and exit activity
Bats repeatedly using the same roof gap, vent, or opening can reveal an active access point.
Droppings below a roost
Accumulated droppings beneath an opening or in an attic may indicate a regular roosting location. Avoid handling unknown material.
Bats around the roofline
Repeated flight close to one section of a building may warrant an inspection.
Why it matters
Activity inside occupied spaces
A bat that enters a room should not be handled. Keep people and pets away and seek appropriate assistance.
Timing considerations: Exclusion work must account for whether bats are present and whether young bats may be unable to leave.
How Cragoe helps
Inspection of the structure
We evaluate likely entry points, roosting areas, exterior activity, and conditions around the roofline.
A carefully timed exclusion plan
When exclusion is appropriate, the technician explains how access will be addressed and why timing matters.
Repair and prevention recommendations
After bats are confirmed out, appropriate openings can be sealed or screened to help prevent re-entry.
Prevention and monitoring
Maintain roof and vent openings
Repair damaged screens, vents, flashing, and construction gaps when it is appropriate to do so.
Do not seal an active opening
Closing a gap while bats are inside can trap them in the structure. Have the activity evaluated first.
Watch for recurring use
Observe the roofline near dusk for repeated entry or exit at the same location.
Keep occupied spaces separated
Maintain interior attic access doors and other barriers between roosting areas and living spaces.
Southern California conditions
Bats may use roof gaps, vents, attics, and other sheltered building spaces in both developed neighborhoods and properties near open land. The location of the roost, building construction, and timing of activity all matter when planning next steps. Cragoe begins with an inspection and explains the appropriate exclusion or monitoring approach for the property.
