I have  a ant problem in one of my units. It's a lower level unit. And it's in mn and it's almost Dec. It's cold out. Anyway Told the tenant to get some traps bait/ poision. Or get an exterminator? problem Lasted for 3 weeks Now.

first need to identify the particular ant species.  Some feeds on sweet some fat some switches.

ants needs water so most likely they are outside and trailing to the inside for food.

once you figure out which type of ants you can start with a bait such as Terro that you can buy from the big box store.  Put a few drops on the trail and wait a few days.

if that doesn't work you need a more industrial strength solution.  My suggestion would be to order a product called Phantom from various online DIY pest control stores.  Follow instructions VERY CAREFULLY and treat the inside except food prep areas, OR a product called Termidor, and treat the outside, or do both.  The two prone Phantom inside Termido outside works as a one two punch but usually one is enough.

Good luck.
