Across Australia, bats and flying foxes occupy roof voids, ridge cavities, parapets, and church belfries on residential, commercial, and heritage sites. All Australian bat species, both microbats and flying foxes, are protected wildlife under the Environment Protection and Biodiversity Conservation Act 1999 and the wildlife or nature conservation act of every state and territory. Several flying fox species, including the Grey-headed Flying-fox and the Spectacled Flying-fox, carry additional EPBC threatened-species listings. The lawful management program is exclusion only, permit-driven, and timed around roost-occupancy and breeding-season windows specified by state legislation. Lethal control sits outside the state Wildlife Act, the EPBC Act 1999, and POCTA and outside the animal welfare requirements governing handling and dispatch.

The lawful program runs through three components. Identification of the access point, often a soffit gap, ridge cavity, parapet detail, or open belfry louvre, locates where the bats are entering and exiting the structure. Exclusion of that access with a one-way valve, installed when the lawful timing window is open under state legislation, allows the bats to leave during evening foraging and prevents re-entry. Habitat management around the building, including pruning back trees that frame the building line and resetting the conditions that drew the roost, reduces the likelihood the access reopens after the exclusion seals. The sequencing of those three components against the lawful timing window decides whether the program is lawful or unlawful.

Timing is the variable that decides whether the work runs. Roost-occupancy and breeding-season windows differ by species and by state. Microbat exclusion typically runs outside breeding-season concentration; the typical southern-Australian window opens through autumn into early winter. Flying fox exclusion is constrained by camp occupancy and dependent-young periods that vary by species and latitude. State legislation specifies the lawful windows in each jurisdiction. Heritage building permits issued under state heritage acts interact with the wildlife permit and the exclusion timing window; sequencing those three approvals matters because failure to align stalls the project for an entire breeding cycle. Pest IT supplies state-by-state frame.

AvePro Bird Netting and exclusion mesh handle the structural exclusion layer for bat access points. Mesh aperture matches the species: 19mm for microbat exclusion, 50mm for flying fox roost exclusion. Frame integrity, edge sealing, and detailed work at the access-point geometry matter as much as the mesh aperture itself, particularly on heritage building parapets, ridge cavities, and church-belfry openings where the spec requires minimal visual impact on the building line. AvePro Birdwire and AvePro Bird Spikes handle ledge and parapet exclusion where mesh is not the right format. The Building Netting collection holds the cross-species exclusion-netting catalogue across bird, bat, and possum work.

AvePro bird dropping remover and sanitiser is used in pre-install cleanup of roof voids and cavities where bat droppings have accumulated. The accumulation needs clearance before the exclusion install seals the cavity, and the cleanup runs under hygienic precautions. PPE for cavity cleanup work includes P2 or N95 respirator, eye protection, gloves, and full coverage; wet-down protocols suppress aerosolisation of dried droppings. Australian Bat Lyssavirus risk and Hendra virus risk together make handling a permit-and-vaccination matter, and the relevant documentation Pest IT supplies walks both pathways at field-pestie depth.

Many heritage roof voids and commercial cavity sites carry multi-species pressure across bat, possum, and bird. Exclusion sequencing across the species requires careful timing because each species has its own roost-occupancy and breeding cycle and its own lawful timing window. The Exclusion and Proofing Systems collection holds the multi-species program-design layer. The Gutter and Cavity Protection collection holds the cavity-exclusion sub-territory across all three species. The Buildings and Infrastructure Catalogue holds the heritage-and-asset-management procurement frame for the heritage facilities manager and asset manager. The Residential and Solar Catalogue holds the residential roof-void and solar-array-cavity sub-territory.

Pest IT supplies the exclusion equipment, the documentation pack, and the brand-and-spec briefing through the AvePro Signature Range. The operator carries the permit and the lawful timing. For the moment a contractor's site assessment names bats on a building, the Free Design Service maps the access points, the species at the site, the lawful timing window, the equipment selection at the right mesh aperture, and the documentation pack that supports permit-compliance. Trade pricing applies to every approved trade account; the Pestie Catalogue is the trade hub for stocking and reorder.
