Why Seminole County needs hydrilla

Lake Jesup is notorious for hyacinth blooms that drift into residential canals. Retention ponds in Lake Mary and Longwood subdivisions routinely trap floating vegetation that HOAs must manage.

Seminole County sits at the convergence of the St. Johns River and Lake Monroe, with Lake Jesup feeding in from the south. Lake Jesup is notorious for hyacinth blooms that drift into residential canals along Sanford and Oviedo. Stormwater retention ponds in Lake Mary and Heathrow subdivisions are some of the most actively managed in Central Florida.

Hydrilla on Seminole County water

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.

How we handle Seminole County jobs

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

Hydrilla pricing in Seminole County typically runs $1,800–$6,500 per visit. 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%. Pricing is consistent across Central Florida — local mileage adjustments are minimal.

Do you serve Seminole County for hydrilla?+

Yes. Hydrilla Removal is one of our most-requested services in Seminole County and surrounding Central Florida water bodies. We respond within 24 hours and schedule on-site inspections within 5–7 business days of contact.

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.
