Okay, the user sent "ant nest". Let me check the translation rules again. The first rule is to translate all content into Simplified Chinese. The second says if it's already in Simplified Chinese, leave it as is. The third is to provide only the translation without explanations.
So, "ant nest" is in English. I need to translate it. The direct translation would be "蚂蚁巢" or "蚁巢". Both are correct, but "蚁巢" is more concise. Let me confirm if there's a standard term. In Chinese, "蚁巢" is commonly used for ant nest. So the translation should be "蚁巢". No need for explanations, just the result.
