Thorn Pest Services Tips for keeping harvester ants away

How To Keep Ants Away
Pest control experts
  • Trim back any shrubs or trees that come into contact with buildings. When plants touch a home or building they create an easy way for ants to crawl onto and access the building.

  • Seal all potential ant entryways. Common entry ways are around windows, doors, and utility lines.

  • Keep dry pet food in sealed bins and clean up any spills.

How to Get Rid of Ants
