❌ Common Pitfalls
Using 'Peste' Incorrectly
Mistake: "Using 'peste' when talking about crop damage or insects."
Correction: While 'peste' means 'plague' (especially historical diseases), 'plaga' is the better word for modern problems like insect infestations or agricultural pests.

Context is Key
When referring to a historical disaster like the Black Death, both 'peste' and 'plaga' can be used, but for specific modern insect problems, stick to 'plaga'.

Frequently Asked Questions
Is 'plaga' only used for insects?
'Plaga' most often refers to biological problems like insects, rodents, or crop diseases. However, it is also very commonly used to talk about large, destructive problems or annoyances, like 'la plaga del crimen' (the curse of crime).
How is 'plaga' different from 'peste'?
While both can mean 'plague,' 'peste' is usually reserved for serious infectious diseases (like the bubonic plague) or sometimes used informally to mean 'a bad smell.' 'Plaga' is the standard word for widespread animal or insect infestations and figurative problems.
