What’s different about Ashgrove
- Older housing: timber Queenslanders have open sub-floors, timber cladding and large roof spaces that give cockroaches, rodents and spiders shelter.
- Tree canopy and vegetation: Ashgrove’s mature street trees and gardens provide bridges onto roofs for roof rats and possums, and shaded, humid microclimates for cockroaches.
- Creeks and moisture: the Enoggera Creek corridor and associated low-lying parkland retain moisture, favouring mosquitoes after rain and providing habitat for rodents.
- Gardens: large, established gardens with mulch, compost and fruit trees attract Australian cockroaches, ants and rats.
- Hilly blocks: under-house storage and retaining walls on sloping sites create sheltered, rarely disturbed spaces where redbacks and cockroaches settle.
