vermin
A collective term for small animals perceived as harmful, annoying, or disgusting, especially insects or rodents. The word often has a derogatory connotation.
Im Keller hatten wir ein Problem mit Mäusen und anderem Ungeziefer.
In the basement, we had a problem with mice and other vermin.
The word has an interesting origin. 'Geziefer' used to refer to animals that were suitable as offerings to gods. The prefix 'Un-' reverses the meaning, so 'Ungeziefer' (vermin) originally meant 'unclean' animals that were not allowed to be sacrificed.
In der alten Speisekammer gab es viel Ungeziefer.
There was a lot of vermin in the old pantry.
'Ungeziefer' (vermin) is a collective noun and is used almost exclusively in the singular, even when talking about many animals. A plural form 'die Ungeziefer' practically does not exist.
Wir müssen etwas gegen das Ungeziefer im Garten tun.
We have to do something about the vermin in the garden.
The word is often used with verbs like 'bekämpfen' (to fight/control) or 'entfernen' (to remove). Typical animals referred to as Ungeziefer (vermin) are cockroaches, moths, ants, or mice.
Ein Kammerjäger wurde gerufen, um das Ungeziefer zu bekämpfen.
An exterminator was called to control the vermin.
insect
'das Insekt' and 'das Ungeziefer' can both refer to small animals, especially when talking about animals in the house or garden. 'Insekt' is neutral and biologically more precise. It only says which animal group an animal belongs to. 'Ungeziefer' is a collective term for small animals that are seen as annoying, harmful, or disgusting. The word sounds clearly negative and can also refer to animals that are not insects, for example small rodents. Learners may confuse the words because many kinds of vermin are insects. If you want to speak neutrally, use 'Insekt'. If you want to emphasize annoyance or disgust, 'Ungeziefer' fits.
In der Küche hat meine Schwester Ungeziefer entdeckt und ruft den Vermieter an.
My sister discovered vermin in the kitchen and is calling the landlord.
Im Sommer hilft sie einem Insekt aus dem Glas.
In summer, she helps an insect out of the glass.
