Fairly common thing here.
Grease ants are another story. I bought some stuff that is supposed to kill both (terro not work on grease ants), but the ants ignored that stuff too. However.....
If you place a tiny piece of catfood on the cardboard, let them get started, you can then drizzle the poison on top of the catfood, and they will just keep at it.
So... I have a problem.
I have ants. More specifically, my apartment has ants. I don't do well with bugs, including harmless, clean little tiny sugar/oil/grease ants.
I'm sure they're coming up from the basement now that it's warm out and their nests are stirring and looking for food. They're on my bedroom floor but I can't always see them -- they run along the black groves between the floorboards. I only see 2-3 at a time and I get 'em with TP and kill/flush 'em. But last night I found them in the dining room, too -- the same wall my bedroom shares. It's not an infestation -- I only see a few at a time, and I'll see maybe 1-3 in random places in the dining room, and I get 'em, but las tnight, I just started vacuuming them. Then I had to clean my entire kitchen floor and find a new home far away for the cat food bowls, b/c if the ants find the cat food, I'm eft.
I bought two kinds of ant poison today, and I need to go to the basement to see if I can put some where the ants are coming into my place.
I hate this.
