terro liquid ant bait....Just watch to see where they go, put the bait down there. They will carry the liquid back to the nest.
Eventually the ants coming to the trap for the liquid will get smaller and smaller (in size)
Get some PAM or spray vegetable oil and spray the hole they come in through or just the whole baseboards. That stops them. You can clean it up in a week and respray. It doesn't get dirty.
Boric acid poweder in the cracks around the floor.
I moved into a new house and now every time the weather turns warm the sugar ants come out. My room is clean, no food or drinks. What to do????
