Common Mistakes to Avoid
- 1
Working without a state pesticide applicator license — it's illegal and results in fines and business closure
- 2
Not building recurring service contracts — one-time treatments are less valuable than quarterly service agreements
- 3
Underestimating the value of a pest control route — a recurring book of several hundred customers at typical quarterly subscription pricing produces a substantial annualized recurring revenue base
- 4
Not investing in termite treatment capability — termite inspections and treatments are high-margin work
- 5
Skipping pollution liability insurance — a pesticide misapplication claim can exceed your general liability limits
