Our story
Built on trust and follow-through
Complete Pest Control started as a mother-and-son family business founded by Marianne Nielson and Casey Hanson. We’ve grown through word of mouth by showing up on time, explaining what we’re doing, and treating every home like it’s our own.
Today, we serve St. George and nearby communities with inspections, targeted treatments, and recurring plans designed for long-term prevention—so you can feel comfortable at home and confident at work.
How we work
A simple, prevention-first process that keeps pests from coming back.
Step 1
Inspect and identify
We look for entry points, nesting areas, moisture issues, and pest activity—then explain what we find in plain language.
Step 2
Treat with care
We use safe, effective products and apply them where they’re needed most—focused on results and minimal disruption.
Step 3
Prevent for the long term
We reinforce the perimeter and share practical recommendations to help keep pests out between visits.
