Rat in Spanish: How to Say Rata, Ratón and Report a Rat Problem

If you’ve spotted a rat in your Spanish rental, in the garden, or scurrying along a drainage channel, the word you need is la rata. It’s a feminine noun, so the article changes with number: one rat is una rata, several rats are unas ratas or, more commonly when reporting a problem, simply las ratas.

Rata vs Ratón: The Confusion That Matters

English speakers often reach for one word to cover both animals, but Spanish treats them as genuinely different problems. La rata is the larger rodent: brown rat (Rattus norvegicus) or black rat (Rattus rattus), the kind found around sewers, refuse bins, gardens, and agricultural land. El ratón is the house mouse (Mus musculus) — smaller, more likely to be indoors, and generally considered a lesser (though still unwelcome) problem.

This distinction matters practically. When you call a pest controller or write to your landlord, naming the correct animal changes the treatment plan: rat control typically means exterior bait stations, burrow treatment, and sealing larger entry points, while mouse control focuses on interior snap traps or glue boards and sealing gaps as small as a coin. Say “ratas” when you mean rats — using “ratones” for a rat problem can get you the wrong response, or a technician who under-prepares for a bigger job.

Gender and Plural

Rata is feminine and regular. The singular is la rata, and the plural simply adds an -s: las ratas. Adjectives describing it also take the feminine form — a “big rat” is una rata grande, not un rata grande. Raton, by contrast, is masculine: el raton, plural los ratones (note the accent shifts and an “e” is added before the plural -s, a normal Spanish spelling rule for words ending in -n).

Pronunciation

Rata is pronounced RA-ta — two short syllables, stress on the first, with a single tapped “r” (not the strongly rolled “rr” sound). Raton is ra-TON, stress on the final syllable, which is why it carries a written accent on the “o.” Getting the stress right matters: shifting it can make you sound like you’re saying an unrelated word.

Regional Variants

Standard peninsular Spanish uses rata and raton everywhere — there is no major regional substitute the way “curiana” exists for cockroach in Andalucia. You may occasionally hear the diminutive ratita used affectionately (for a pet mouse, say), but never for a pest report. Stick with rata and raton and you will be understood from Galicia to Andalucia.

Phrases to Report Rats

Use these when writing to a landlord (casero) or the community of owners (comunidad de propietarios):

• There are rats in the apartment/garden — Hay ratas en el piso/jardín
• We’ve found rat droppings — Hemos encontrado excrementos de rata
• We need a rodent treatment — Necesitamos una desratización
• Who is responsible for paying? — ¿Quién es responsable del pago?
• The rats are coming from the drains/sewer — Las ratas salen por los desagües/alcantarillado
• Can you call an exterminator? — ¿Puede llamar a un fumigador?
• I want to report a rat problem to the council — Quiero denunciar un problema de ratas al ayuntamiento

Spanish rental law generally puts responsibility for pest control in shared and structural areas on the landlord, while tenant-caused infestations may fall on you — put every report in writing (email or WhatsApp) so there’s a record.
