harmful insect or small animal
An insect or small animal that causes damage to plants, food, homes, or health.
用法パターン：
[someone] has a problem with [pests]
よくある間違い：
Learners sometimes use "pest" for any insect, even when it is not harmful. In English, an insect or animal is called a "pest" only when it causes damage or trouble (for example, mosquitoes, cockroaches, rats). Learners may also confuse the noun "pest" with the verb "pester"; "pest" is the thing that causes trouble, while "pester" is the action of bothering someone.
類義語
vermin (Often refers to dirty or disease-carrying animals like rats; slightly more negative or vivid than "pest".)
|
nuisance (Broader and more general; can be anything annoying, not only insects or animals.)
|
bug (Informal and usually limited to insects or small crawling creatures, especially in homes and gardens.)
対義語
beneficial insect (Refers to insects that help crops or the environment, the opposite role of a pest in agriculture or gardens.)
