I made up the traps with both bait included in the kit. Ants were attracted to the bait trays, but most died before going back to the nest. In 2 days there were no ants. Then three days later, there were ants again, though not as many. The traps were still on the floor and were not empty.
I am a very clean person and there is no food anywhere for them to eat. They are coming from the garden that borders the kitchen wall, where they are being seen. I have now put granules along the outside wall and will see if that works. If not, I will be getting a professional exterminator.
