When you’ve got a recurring problem, multi-species infestation, or very large property, professional pest control is almost always worth it. They bring diagnosis, strategy and execution.
If you work full-time, DIY might still mean hours of prep, research and follow-up. A pro frees you from that and often finishes faster and more thoroughly.
Bottom line: Evaluate the scope. Small insect visits = DIY. Structural pests or frequent returns = professional. And either way, combine treatment with sanitation, exclusion and monitoring for best results.
