Hydrilla vs. native eelgrass: how to tell them apart
Native eelgrass is fish habitat. Hydrilla is an invasive that smothers it. Here's how to identify what's in your water before you start treatment.

Hydrilla Removal across Central Florida
Mechanical hydrilla removal for private Florida lakes, ponds, and HOA waterways.
Typical price range
$1,800–$6,500
Per-visit pricing on a 1–3 acre private lake. Heavy initial cleanups can be 2× the recurring rate. Quarterly maintenance plans drop per-visit cost 30–40%.
What is hydrilla and why it matters
Hydrilla (Hydrilla verticillata) is the single most damaging aquatic invasive in Florida. It tops out at the surface in dense mats, blocks navigation, eliminates native submerged vegetation, and is functionally impossible to eradicate once established. Mechanical harvesting and ongoing maintenance is the only realistic management path for private waterfront owners.
Florida loses an estimated $14M per year to hydrilla management costs alone. Untreated, it eliminates fish habitat, kills shoreline property values, and renders docks unusable.
Signs you need hydrilla service
!Surface mats topping out in 3–8 ft of water
!Boat propellers tangling in the shallows
!Loss of native eelgrass and pondweed
!Fish kills following herbicide spray events
!Reduced dissolved oxygen at depth
The problem
Why DIY and herbicide-only fail
Hydrilla grows up to one inch per day, fragments easily, and reproduces from tiny stem pieces. A single boat propeller can spread it lake-wide in a season. Florida classifies it as a Class I Prohibited Aquatic Plant. State spray operations focus on public navigation channels — not private shorelines.
Our approach
How we handle it
We use surface-cutting harvest boats to slice and lift hydrilla mats off the water column, then haul biomass to a permitted upland disposal site. Cuts are made at 4–6 ft depth so subsurface tubers regrow slower and native eelgrass has light to recover. Maintenance schedules typically run 3–4 visits per growing season.
- ✓Surface harvester boats — no broadcast herbicide
- ✓Cuts measured at 4–6 ft depth to spare native eelgrass
- ✓Biomass hauled to permitted upland disposal
- ✓3–4 visit annual maintenance plans available
- ✓FWC compliance documentation included

Estimate
Estimate your hydrilla cost
Per-foot pricing scaled to shoreline length, density, and access. Per-visit pricing on a 1–3 acre private lake. Heavy initial cleanups can be 2× the recurring rate. Quarterly maintenance plans drop per-visit cost 30–40%.
Every estimate still requires an on-site inspection before we commit to a firm number.

FAQs
Hydrilla Removal — frequently asked questions
Can hydrilla be eradicated?+
No, not realistically. Hydrilla produces subterranean tubers that remain viable for 4–7 years even after the surface plant is removed. The goal is suppression to under 5% surface coverage through ongoing maintenance.
Will the state remove hydrilla from my private lake?+
No. The Florida Fish and Wildlife Conservation Commission and water management districts only treat public navigation channels and state-owned waterways. Private lakes, ponds, and HOA water bodies are the property owner's responsibility.
Do you spray herbicide for hydrilla?+
We specialize in mechanical removal because broadcast herbicide on hydrilla creates massive decaying biomass that crashes oxygen levels and triggers fish kills. Targeted spot treatment of regrowth between mechanical visits is sometimes appropriate.
How much does hydrilla removal cost?+
On a 1–3 acre private Florida lake, expect $1,800–$6,500 per harvest visit depending on coverage density and access. Annual maintenance plans usually run $7,000–$22,000 for 3–4 visits per growing season.
How fast does hydrilla come back after removal?+
On an unmaintained lake, surface coverage returns in 6–10 weeks during summer. With a 3–4 visit annual maintenance plan, coverage stays under 5% indefinitely.

Mechanical vs. chemical aquatic weed control: tradeoffs
Spray is fast and cheap. Mechanical is durable and selective. The right answer depends on the species, the season, and what you need the lake to do.
