How to Say "bug" in Spanish
The most common Spanish word for “bug” is “bicho” — use this informal term for any small creature, especially an insect, or for a mild illness like a cold or flu..
bicho
/bee-cho//ˈbitʃo/

Examples
¡Cuidado con ese bicho en la pared!
Watch out for that bug on the wall!

The children were looking for critters under the rocks.
Creo que agarré un bicho en el avión y ahora tengo fiebre.
I think I caught a bug/virus on the plane and now I have a fever.
Always Masculine
Even if the creature is female, 'bicho' is always used with masculine articles (el bicho, un bicho).
Catching a Sickness
When referring to catching an illness, Spanish often uses 'agarrar un bicho' (to grab a bug) or 'coger un bicho' (to catch a bug).
Confusing Gender
Mistake: “La bicha (unless referring to a regional slang for a female person)”
Correction: Use 'el bicho' for insects/animals; the feminine form 'bicha' is rarely used in this context.
insecto
/een-SEK-toh//inˈsekto/

Examples
La mariposa es un insecto hermoso.
The butterfly is a beautiful insect.
La abeja es un insecto muy trabajador.
The bee is a very hardworking insect.
Hay muchos insectos en el jardín durante el verano.
There are many bugs in the garden during the summer.
¡Quita ese insecto de mi mesa!
Get that bug off my table!
Masculine Noun
This word is masculine, so you should always use 'el' or 'un' with it (el insecto, un insecto), even if you are talking about a female bug!
Insects vs. Spiders
Mistake: “Calling a spider 'un insecto' in a biology exam.”
Correction: While people often call any small crawly thing an 'insecto' or 'bicho', technically spiders are arachnids. Use 'insecto' strictly for six-legged creatures if you want to be precise.
virus
BEE-roos/ˈbiɾus/

Examples

My computer is slow, I think it has a virus.
