Princeton Scope and Scheduling Notes

For pest control, that means the pest control quote should explain the target pests, treatment zones, follow-up policy, product category, and conditions the homeowner must correct.
| Estimate item | Why it matters | Question to ask |
|---|---|---|
| Follow-up policy | A cheap first visit can be poor value if retreatment or monitoring is excluded. | How many visits are included, and what triggers a no-charge callback? |
| Warranty limits | Some warranties exclude sanitation issues, structural entry points, or heavy infestations. | What conditions would void the service guarantee? |
| Interior access | Pets, children, allergies, and tenant access can change preparation and timing. | What prep steps, product category, and re-entry window apply? |
| Exterior conditions | Moisture, mulch, vegetation, gaps, and entry points affect whether treatment holds. | Which exterior conditions should the homeowner correct before or after service? |
