Crows
The carrion crow (Corvus corone) is the most widespread corvid in urban Belgium. Omnivorous and highly intelligent, it tears open bin bags, attacks crops and can turn aggressive during nesting.
On site within 24h
Highly adaptable, corvids quickly work around standard deterrence techniques. Physical protection (tensioned wires, netting) combined with durable visual scaring remains the most effective method. The legal regime depends on the species and the region: the rook and the jackdaw are protected under the Birds Directive, while the carrion crow and the magpie fall under hunting law. Either way, destruction goes through a regional derogation or the holder of the hunting rights.
Identify
Signs of infestation
- Large black birds (45 to 65 cm) in noisy groups, especially active at dawn
- Droppings concentrated on roof lines, aerials, flat roofs and overnight gathering spots
- Bin bags and rubbish bins tipped over or torn open in the morning (foraging for food)
- Large stick nests in trees or pylons (rooks and crows nesting in colonies)
Where it's found
The carrion crow (Corvus corone) is solitary and urban. The rook (Corvus frugilegus) is colonial and nests in groups (a rookery) in tall trees. Both species are present throughout Belgium, with high density in suburban areas.
Impact
Associated risks
Protected status
The rook and the jackdaw are protected under the Birds Directive; the carrion crow and the magpie fall under hunting law, regulated by region. No trapping or culling without an exemption from the DNF (Wallonia), ANB (Flanders) or Bruxelles Environnement. Physical deterrence, however, requires no permit.
Property damage and health risks
Droppings corrode roofing materials. Rook rookeries generate significant noise and odour. Crows systematically tip over bin bags, scattering waste.
Good practice
Prevention
- 01Use locked rubbish bins: access to waste is the main factor that attracts and keeps corvids coming back
- 02Visual deterrents (decoy falcon, reflectors): temporary effectiveness of 2 to 4 weeks, as corvids get used to them
- 03For rookeries on private property: report to the DNF (Wallonia) or Bruxelles Environnement for an exemption assessment
Frequently asked questions
What you're asking
Is the carrion crow protected in Belgium?
Not freely, and the regime depends on the species. The rook and the jackdaw are protected under the Birds Directive: destroying them requires a derogation from the DNF in Wallonia, the ANB in Flanders or Bruxelles Environnement. The carrion crow and the magpie fall under hunting law, with conditions set per region. Antinox never carries out destruction: we install physical deterrence (tensioned wires, netting, scarers), which is legal and needs no prior authorisation.
How do I protect my waste from crows?
Crows can open ordinary bin bags in seconds. Effective solutions: latched closed containers, protective netting over collection areas, removing accessible food sources. For high-traffic commercial areas, a tensioned cover net over the bins is the most reliable.
Do crows attack passers-by?
Occasionally, during the nesting season (March-June). A crow with a nest near a walkway may swoop at passers-by to defend its young. This behaviour is temporary and stops once the young leave the nest — usually within 3 to 4 weeks. Marking off the area is enough in most cases.
