The Bowers approach
From evidence
to a clear plan.
The exact method depends on the species, activity, structure, season, and conditions found during inspection.
- 01
Identify
Confirm the insect and distinguish box elder bugs from similar species before choosing treatment zones.
- 02
Target
We confirm the insect, evaluate gathering and entry areas, address exterior activity, and prioritize exclusion before overwintering.
- 03
Prevent
Address entry points, moisture, food, nesting conditions, and seasonal pressure that can support renewed activity.
