Often, carpenter ant nests found indoors are satellite nests that can be traced back to a parent colony outdoors.
Look for nests in:
- Trees
- Stumps
- Roots
- Fence posts
- Landscape timbers
- Other wood structures
Try removing the wood with the parent colony. When that is not possible, contact a professional to treat the carpenter ant nest.
Trim branches that overhang buildings or electrical wiring to avoid giving carpenter ants easy access to your home.
