Girona is one of Catalonia’s most beautiful cities – famous for its colourful houses along the Onyar river, medieval Jewish Quarter (El Call), and cathedral. But four rivers converge here, the old town has centuries of infrastructure beneath it, and the inland location means hotter summers than the coast. Cockroach prevention is part of life in Girona.
Why Girona Gets Cockroaches
- Four rivers – The Onyar, Ter, Güell, and Galligants converge in and around the city, providing humidity and habitat
- Medieval old town – The Barri Vell and Jewish Quarter have drainage infrastructure dating back centuries
- Inland heat – Girona is hotter than the Costa Brava coast in summer, regularly exceeding 35°C
- University population – Student accommodation can have inconsistent prevention in shared buildings
- Restaurant and tourism growth – Girona’s food scene has exploded in recent years, increasing food waste
Girona's Season
Cockroach activity peaks June through September. Riverside properties and the old town face the longest season due to persistent humidity from the rivers.
Area Risk Profiles
Barri Vell & El Call (Jewish Quarter)
The medieval heart of Girona – narrow streets, stone buildings, ancient foundations.
- Oriental cockroaches from centuries-old drain infrastructure
- Stone walls with innumerable gaps and entry points
- Proximity to the Onyar river adds persistent humidity
- Professional annual treatment strongly recommended
Cases de l’Onyar (Riverside Houses)
The iconic colourful houses hanging over the Onyar river.
- Direct exposure to river humidity
- Oriental cockroaches from the river environment and old drains
- Beautiful but extremely old buildings with limited sealing options
- Focus on drain covers and gel bait as primary defence
Eixample & Modern Girona
The newer districts outside the old walls.
- Lower risk overall – more modern construction
- Standard apartment prevention: drain covers, gel bait, sealing
- German cockroaches in apartment block kitchens
- Properties near rivers still face elevated humidity
Montjuïc & Palau
Residential areas on the hills around the old town.
- Villa and house properties: perimeter treatment
- Further from river humidity but still within city drainage network
- Standard prevention protocol is sufficient
- Clear garden vegetation from building perimeters
