How to use this evidence
A clear photo can support a visual comparison with known pest evidence.
A photo alone cannot confirm the source or extent of an infestation. Check for matching physical evidence nearby.
What you found
Ant trails show where ants are moving between a colony and a resource. Following the trail before cleaning it away helps locate entry points, food sources, or nesting areas.
Common places to check
- Inspect countertops and nearby hiding spots for matching evidence.
- Inspect window sills and nearby hiding spots for matching evidence.
- Inspect door thresholds and nearby hiding spots for matching evidence.
- Inspect foundation edges and nearby hiding spots for matching evidence.
- Inspect trees and nearby hiding spots for matching evidence.
