Garden Ant Infestation: Need Local ID and Extension Help

Montana (Zone 3-4). Ants everywhere: pull carrot, 50+ ants crawl out, carrot like maze. Aphid control didn't remove ants.

Steps

1. ID ants first — determines source and treatment.
2. Contact county Ag Extension (courthouse) for "house call" — know regional ants.
3. Local garden center (not big box) for advice.
4. If can't find Extension number, provide county — expert will locate.
