Today, the team at Complete Ground Control was called out to treat a commercial facility in Willmar, Minnesota for an active cockroach infestation.
Unlike one-time pest treatments for ants or spiders, roaches require a more thorough, long-term approach.
These pests multiply fast, hide in tight spaces, and can contaminate food areas if not handled quickly and completely.
We performed a full interior treatment and deployed monitoring systems to assess ongoing activity.
This ensures we not only kill off the existing population but also determine if the infestation is spreading beyond the initial site.
Cockroach Treatments Require Follow-Up
The truth about roach control?
One visit is almost never enough.
Here’s how our commercial roach treatment plan works:
- Initial service – Apply gel baits, dusts, and sprays in critical areas
- Install monitors – Track activity over time
- Follow-up visits – Usually 2–3 total, depending on size of the infestation
During each visit, we inspect, treat, and re-monitor the areas to ensure progress is being made.
Cockroach infestations often require adjusted strategies between visits based on behavior and movement.
Steps in a Commercial Roach Treatment Plan
| Step | Purpose | Frequency |
|---|---|---|
| Initial Treatment | Kill active roach population | Day 1 |
| Monitoring Setup | Detect activity & hot spots | Day 1 |
| Follow-Up Visits | Reinforce control and adjust plan | Weekly to Biweekly |
Why Monitors Matter
Monitors are one of the most powerful tools in professional pest control.
They help us:
- Confirm the infestation’s location
- Detect any spread into new rooms
- Measure success between visits
Cockroaches are nocturnal and excellent at hiding.
Monitors do the watching when we can’t.
Attic Inspections Turn Up a Surprise
After the commercial job, our team inspected multiple residential attics in Willmar.
Each one had signs of bat activity.
What we saw:
- Guano (bat droppings) on insulation
- Dark rub marks near entry points
- Fluttering sounds near soffits and vents
Because bats are a protected species, we won’t begin exclusions until overnight temps are consistently above 40°F. This protects young pups during maternity season.
Signs You Have Bats in Your Attic
| Sign | What It Indicates | Where to Check |
| Guano | Active or recent bat presence | On insulation, in corners |
| Squeaking/Fluttering | Roosting in wall or attic spaces | At night near attic vents |
| Dark rub marks | Entry point from repeat use | Around soffits, vents |
Bat Season Starts Above 40 Degrees
We’ve scheduled exclusions to begin in a couple of weeks—weather depending.
This delay ensures:
- All bats have safely left at night
- No pups are trapped during development
- Legal and humane compliance with state regulations
In the meantime, we prepare homes by:
- Identifying all active entry points
- Planning placement of one-way bat valves
- Prepping materials for full sealing
Bat Exclusion Timeline
| Step | Goal | Timing |
| Inspection | Confirm presence, map entry | Now |
| Install One-Way Doors | Let bats exit without reentry | Above 40°F nights |
| Seal Home Fully | Prevent future access | Post-exit confirmation |
Why We Think This Is Important
Pest control is about more than just sprays and traps.
It’s about understanding timing, biology, and long-term prevention.
In this case, we:
- Handled a serious cockroach problem that could’ve impacted a business’s reputation
- Identified multiple homes with bat issues before they worsened
- Helped homeowners prepare ethically and legally for bat removal
Whether it’s a commercial kitchen or a quiet attic, Complete Ground Control is equipped to respond, inspect, and solve the problem—the right way.
