A building in a nearby neighbourhood seems to be infested with mice. A TV-News reporter was interviewing one of the janitors who said: "We tried to get rid of them but I don't think we used the right insecticide". Hey, wait, mice are not insects. I don't think we could use "insecticide" here, or could we? Is there a word or compound-word for a substance that kills mice? I thought of "pesticide" but I'm not sure it works in a domestic rather than in an agricultural context.

    Try muricide perhaps?

  • @Robusto I've found muricidal as "possessing the muricide instinct; inclined to kill mice" It seems to be the instinct to kill mice, not the product.

  • I still think it applies. You're applying one aspect of the adverb form to the entire word.

  • @Robusto Well, if you still say so... you must be right. :-)

  • It is the most specific term I can think of. @chasly's "rodenticide" is undoubtedly a lot more common, but includes other rodents.

  • Quite so, but does rat poison work for mice? Aug 28 '15 at 20:38
  • Rat and mice poisons are the same products. "Rat poison" has 530 000 occurences in Google, whilst "mice poison" only occurs 12 000 times.

    Actually, some rat poisons do not work on mice. The most common rat poison is one that causes rats to bleed internally. It's a relatively "safe" poison because most other animals (including people and mice) have a chemical in their bodies that blocks it's action. To make it into a mouse poison another chemical is added to block the action blocker (but this of course makes the mouse poison more hazardous).
