Dead ants.

[scaeagles]

There is some technical name for these ants - there really is, though I can't think of it. There are a variety of smaller black ants that live in smaller colonies and will typically make their homes under cabinetry. I used to have this problem in my kitchen. I was told that to solve it you need to drill a small hole in the baseboard going through to underneath your cabinet. You then can pump a small amount of a dry powder under the cabinet and plug it. I purchased everything I needed at Home Depot.
