Both positioned as lower-cost alternatives to Mosquito Joe and Mosquito Squad, but with dramatically different fee burdens, growth rates, and system health signals. All data from 2025 FDDs filed with the Wisconsin DFI.

All data from 2025 FDDs filed with the Wisconsin Department of Financial Institutions. Fee burden figures Modeled at $300K gross revenue, Year 5, single territory.
The fee gap between these two brands is substantial and consistent across all revenue levels. Mosquito Authority charges a flat 10% royalty with a minimal marketing floor ($5,500/year or 5% of gross sales, whichever is greater). Mosquito Shield charges 8% royalty — the lowest rate in the cohort — but pairs it with a $50,000/year local advertising minimum (the highest marketing floor in the cohort) plus a 2% brand fund.
At $300K revenue, Authority’s total fee burden is $52,800 (17.6%). Shield’s is $86,000 (28.7%). That’s a $33,200/year difference — the largest fee gap between any two brands in the mosquito cohort. Shield’s lower royalty rate is more than offset by its marketing requirements.
| Revenue Level | Mosquito Authority | Mosquito Shield | Difference |
|---|---|---|---|
| $200,000 | $36,600 (18.3%) | $76,000 (38.0%) | $39,400/yr |
| $300,000 | $52,800 (17.6%) | $86,000 (28.7%) | $33,200/yr |
| $400,000 | $69,000 (17.2%) | $96,000 (24.0%) | $27,000/yr |
| $500,000 | $85,200 (17.0%) | $106,000 (21.2%) | $20,800/yr |
Mosquito Authority has the cleanest system health in the cohort: zero terminations across all three reporting years (2022–2024), consistent positive growth (+5, +10, +7), and the largest system (546 franchised outlets).
Mosquito Shield has the fastest absolute growth (+140 units over 3 years) but also the highest termination counts: 65 in 2023 and 44 in 2024. The system churned at 11–25% per year. Net growth looks positive only because openings outpaced losses.
For a buyer evaluating risk: Authority demonstrates steady, low-churn growth. Shield demonstrates aggressive expansion with significant franchisee turnover.
| Year | Authority | Shield | ||
|---|---|---|---|---|
| Net Change | End Count | Net Change | End Count | |
| 2022 | +5 | 529 | +74 | 369 |
| 2023 | +10 | 539 | +38 | 407 |
| 2024 | +7 | 546 | +28 | 435 |
Mosquito Authority’s initial investment ranges from $54K–$127K, depending on territory tier (Hometown vs. Full-Size). Mosquito Shield’s ranges from $120K–$158K.
Authority’s lower cost floor ($54K for a Hometown territory) makes it the most accessible entry point in the mosquito cohort. A buyer evaluating both should understand that Authority’s Hometown tier is a smaller territory with a lower fee, while the Full-Size tier ($89K–$127K) is a closer comparison to Shield’s range.
Authority costs less to enter, costs less to operate, and has a cleaner system health trajectory. Shield has faster absolute growth, a lower royalty rate (8% vs. 10%), and higher customer retention (85% vs. Authority’s company-owned data).
The core question for a buyer is what Shield’s growth rate means in context of its turnover. Rapid expansion with high churn can reflect aggressive market capture, operational growing pains, or both. The termination data (65 in 2023, 44 in 2024) and the 21% Item 19 exclusion rate for “non-conforming” outlets are data points worth exploring during due diligence.
A capital-efficient buyer focused on unit economics has a stronger foundation with Authority. A buyer willing to pay more for faster growth and a lower royalty rate has a rationale for Shield — but should investigate the churn data closely.
