• Warning issued by researchers at the University of Southern Denmark.
• Invasive garden ants build massive supercolonies in urban environments.
• Ants can loosen pavement tiles and damage household electrical wiring.
• Homeowners are responsible for pest control on private property.
• Tenants should report pest issues directly to landlords or housing associations.

These ants cause serious property damage. They dig beneath pavement tiles and loosen the ground. The ants also move into household electrical systems. This can cause short circuits and power outages in homes.

In Copenhagen, pest issues affect both homeowners and renters. Property owners must maintain their private land and outdoor tiles. If you rent, report pest sightings to your landlord immediately. You can also notify your local housing association.

Inspect garden tiles and patios for loose ground regularly. Keep indoor food packed in sealed containers to deter pests. Contact professional pest control services if you spot supercolonies. Early action prevents costly repairs to electrical systems and paving.
