Most pest control operators in Barcelona work without a valid ROESB licence, quote one price and charge another, and ignore callbacks. Fianza only works with DDD-certified technicians registered with the Generalitat de Catalunya — covering Eixample, Gràcia, Sarrià-Sant Gervasi, Sant Martí, and the rest of the city. Transparent pricing, written quote before any work starts, 12-month guarantee on every job.
Three visits over six weeks, €320 total — same number on the final invoice. The technician showed me his ROESB card before opening the cupboard and walked me through every line of the written quote before spraying. The cockroaches in our Eixample flat are gone and nothing came as a surprise.
We took over the restaurant in October and needed an APPCC contract fast. Fianza sent the same technician every month for 11 visits, each one logged in the APPCC book with the date and the biocida batch number. When the sanitat inspector came in March, he signed it off on the first pass — that's what we needed from a supplier.
Eight weeks after the heat treatment we found one bed bug in the bedroom closet and called Fianza on a Saturday. The same technician who did the original job was at the door within 36 hours, retreatment included, no invoice, no argument. The 12-month guarantee is real — that's why we keep recommending them.
Cada técnico tiene que estar registrado en el ROESB de la Generalitat de Catalunya. Sin registro, no hay trabajo. Comprobamos el número antes de asignar cualquier servicio.
La normativa DDD exige formación acreditada para manipular biocidas. Verificamos que el carnet está al día y cubre las categorías de uso del tratamiento solicitado.
Ninguno empieza a trabajar hasta que tienes un presupuesto escrito con alcance, método y precio cerrado. Si algo cambia durante la visita, te lo explicamos antes de continuar — siempre.
Consumer reviews across Google, Yelp, and habitissimo tell the same story: people are afraid of being scammed. Unqualified operators, hidden charges, treatments that don't work. Fianza was built to solve exactly that.
All Fianza operators are registered with the Generalitat de Catalunya (ROESB) and have completed certified biocide training. You can ask to see their credentials before they start. That's not negotiable — it's the baseline.
No one starts work until you have a formal quote with the full scope, method, and price — in writing. If the price changes, we explain why. You decide. Always.
Every treatment comes with a written 12-month guarantee. If the pest returns within that window, we return to treat it at no additional cost. That's in the contract, not just on the website.
Pre-war buildings in Eixample, Gràcia, and the Gothic Quarter are prime cockroach territory — old drainage and shared walls let colonies spread fast. We identify the species, locate the nest, and eliminate it completely, then seal re-entry points so they don't come back.
Rat activity runs along Barcelona's metro lines, market areas, and older sewer networks — Raval, Barceloneta, and Poblenou see it most. We deploy child- and pet-safe traps and bait stations, placed precisely by our Gencat-certified operators, and monitor until the problem is gone.
Bed bugs spread fast in high-turnover apartments and tourist rentals — a serious problem across Eixample, Gràcia, and the Barceloneta waterfront. We use heat treatment and targeted chemical protocols, and we back every job with our 12-month written guarantee.
Ants nest in the cavity walls common in Sarrià, Les Corts, and Sant Gervasi homes. Wasps take over terraces, roof cavities, and comunitat stairwells across the city. We eliminate the colony at the source — not just the workers you see.
For restaurants, hotels, offices, and communities of owners: we design integrated pest management plans (IPM) that comply with APPCC food safety regulations and Gencat hygiene requirements. Required documentation included.

Preguntar por WhatsApp"We believe the pest control industry in Barcelona has become comfortable taking money from people who have no way to verify who they're hiring. That's wrong. A family with a cockroach problem shouldn't have to worry about being defrauded on top of an infestation."
