Ants in the house are a problem. A control program which includes identification of the specific ant, sanitation, pest proofing, monitoring and inspection is needed to really get rid of the ants. I suggest you read this publication which gives great detail: https://utextension.tennessee.edu/publications/Documents/PB1629.pdf
If you are unable to identify your ants, follow the directions in the publication on collecting ants and bring them to the DE Cooperative Extension Service Office at the Paradee Center, 69 Transportation Circle, Dover DE 19901. There is usually a Master Gardener there Monday-Friday from 9am to Noon at this time of the year.
