These ants are normally found scavenging for food around stoves, ovens or counter-tops in the kitchen.

These ants will eat anything but they typically prefer protein-rich foods like meat, cheese, tofu, beans or soy. The ants are very small and they easily fit through tiny opening, holes, and cracks.

  1. Grease Ants: a professional came to house and sprayed the perimeter, including where I saw the trail entering. I have not located the nest. Do pros need to use a specific type treatment for grease ants, or not? Also, day after treatment many more ants inside than usual. I’ve been baiting inside with both borax and Terro mixtures to no avail. My baiting moved them from the kitchen to the bathroom??!! (The 2 rooms back up against each other) I feel the nest is outside since I’ve seen the trail entering. Pro only did perimeter. Does entire yard need done to address nest? Apologize for so many questions. I’m at my wits end. Thank you very much.
