Marina, Yacht Club & Boat Slip Spider Spraying

Dock Spider & Orb Weaver Eradication

Boat slips, boathouses, and marina docks face relentless pressure from giant fishing spiders (dock spiders) and orb weavers. Spider Squad provides specialized, weather-resistant exterior pest barrier applications across Lake Ontario and Lake Erie marine facilities.

The Marine Spider Challenge: Dock Spiders & Aquatic Midges

Marinas and yacht clubs sit directly on top of massive aquatic insect hatching grounds. Midges, caddisflies, and mayflies swarm marina dock lighting every evening, providing an endless food supply for semi-aquatic dock spiders (Dolomedes) and bridge orb weavers. Spiders colonize boat lifts, cleat lines, canopy covers, and slip framing within days.

⚓ Boat Slips & Lifts

Clean Mooring Areas

We treat boat lift framing, structural pilings, and slip perimeters to stop spiders from nesting in bimini tops, cockpits, and mooring lines.

💧 Weatherproof Durability

Dragnet SFR & Polyzone

We utilize specialized formulations that bind to weathered marine lumber, composite dock boards, and aluminum framing without washing away in wave spray.

🧹 High Rafter De-Webbing

Boathouse Sweeping

We clear heavy web clusters, egg sacs, and insect carcasses from high boathouse peaks and marina clubhouse overhangs.

Approved Marine Facilities & Harbours We Service

Spider Squad services commercial marinas, private yacht clubs, and residential boat docks across Southern Ontario, including:

Frequently Asked Questions

Are your products safe around marine environments?
Yes. Our licensed operators apply targeted, low-drift micro-barrier sprays directly to terrestrial dock structures, pilings, and boathouse framing in strict accordance with Health Canada PMRA label guidelines.
Will the spray damage boat gelcoat or canvas covers?
No. Our professional water-based micro-encapsulated formulations are non-staining and non-corrosive to fiberglass, aluminum, and marine canvas once dried.
Can you treat private residential boathouses?
Absolutely. We treat private boathouses, boat lifts, and lakeside docks across Niagara, Hamilton, Halton, and Haldimand.
