How to Say "insects" in Spanish
The most common Spanish word for “insects” is “insectos” — use 'insectos' when you want to specifically refer to the biological class of insects, characterized by having six legs and three body parts, especially in formal or scientific contexts..
insectos
/in-SEK-tos//inˈsektos/

Examples

Masculine Plural
Since 'insectos' is the plural form of the masculine word 'insecto,' you must use the masculine plural word for 'the' (los) and any descriptive words (adjectives) must also agree, usually ending in -os (e.g., los pequeños insectos).
Gender Error
Mistake: “La insectos (Incorrect use of feminine 'la')”
Correction: Los insectos. Remember, the word is masculine even though the creatures themselves don't have a specific gender assigned in the word.
bichos
/BEE-chohs//ˈbitʃos/

Examples

¡Cuidado! No pises esos bichos.
Watch out! Don't step on those critters.
Making it plural
To talk about more than one 'bicho', we just add an 's' at the end. It always stays masculine, even if the bugs are technically female.
Insecto vs. Bicho
Mistake: “Using 'insecto' in a casual conversation at a picnic.”
Correction: Use 'bicho' for a more natural, everyday feel. 'Insecto' sounds like you are in a science class.
