The Ultimate Guide to a Bug-Free Summer: Spider and Mosquito Control for Lake Boathouses

There’s nothing quite like a summer evening in Northeast Georgia. Whether you’re watching the sunset over the wide expanse of Lake Rabun, enjoying the rugged beauty of Lake Burton, or navigating the sprawling fingers of Lake Hartwell, the water is where memories are made.
But as any lakefront property owner knows, the dream of a peaceful evening on the dock can quickly turn into a battle against two of nature’s most persistent party-crashers: spiders and mosquitoes.
Boathouses, with their wooden structures, proximity to water, and evening lights, are essentially luxury resorts for pests. If you’ve ever walked into a face-full of sticky silk or spent your Fourth of July slapping at mosquitoes instead of watching the fireworks, this guide is for you. At TruServ Pest, we understand how important it is for homeowners to enjoy their waterfront property without constantly battling pests. Here is how to reclaim your waterfront experience this summer.
The Georgia Lake Trio: Why Our Pests are Different
In Northeast Georgia, we aren’t just dealing with "any" bugs. Our specific ecosystem creates unique challenges.
- Lake Rabun: As one of the most visited lakes in the country, the density of docks and boathouses provides a continuous "highway" for pests to move from one property to the next.
- Lake Hartwell: With its massive shoreline, Hartwell has countless coves where water can become stagnant, a prime breeding ground for mosquitoes.
- Lake Burton: The cooler, mountain-adjacent climate can lead to different spider cycles, often resulting in larger, more intricate webs that seem to appear overnight.
The Spider Situation: Beyond the "Eek" Factor
Spiders love boathouses for one simple reason: the food chain. Your dock lights attract midges, moths, and flies. The spiders simply set up shop where the buffet is open 24/7.
The Joro Spider Invasion
If you’ve lived in Georgia for more than a minute lately, you’ve seen them. The Joro spider, an invasive species from East Asia, has taken over the North Georgia canopy. They are bright yellow, blue, and red, and they build massive, golden-tinted webs that can span several feet. While they aren’t harmful to humans or pets, their webs are incredibly strong and can make a boathouse look abandoned in a matter of days.

Common Native Spiders
Alongside the Joros, you’ll find native Orb Weavers and the dreaded "dock spiders" (Fishing Spiders). While Orb Weavers are great for pest control, their messy webs on your boat covers and railings are less than ideal.
How to Reduce Spider Populations
- Web Dusting: This is the most effective manual method. Use a long-handled "cobweb duster" at least once a week. Removing the web forces the spider to relocate. If you do this consistently, they’ll eventually decide your neighbor's dock is a quieter place to live.
- Pressure Washing: A light pressure wash of your boathouse rafters can remove eggs and hidden nests. Be careful not to use high pressure on delicate wood or boat electronics.
- Lighting Adjustments: Spiders don't care about your lights, but their prey does. Switch out standard white incandescent or LED bulbs for yellow "bug lights." These wavelengths are less visible to insects, meaning fewer bugs will congregate at your dock, and the spiders will follow the food elsewhere.
The Mosquito Menace: Reclaiming Your Sunset
If spiders are a nuisance, mosquitoes are a health hazard. In Georgia, they are more than just an annoyance; they can carry West Nile Virus and Eastern Equine Encephalitis. Because boathouses sit directly over the water, traditional yard fogging isn't always enough.

Eliminate Stagnant Water (Even on a Lake!)
It sounds ironic to worry about stagnant water when you’re literally on a lake, but mosquitoes don't breed in the moving, open water of Lake Lanier. They breed in:
- Clogged gutters on your boathouse roof.
- Old tires used as boat bumpers.
- Puddles on uneven dock boards.
- The "cups" of boat covers that collect rainwater.
In2Care Mosquito Stations
For many homeowners on Lake Rabun and Lake Burton, a smart alternative is the In2Care Mosquito Station. Instead of relying on a misting system installed in the rafters, these stations attract mosquitoes to a treated surface. The mosquitoes then help spread the active ingredients to other breeding sites, reducing mosquito populations over time.
Pro Tip: Work with a professional who understands how to place In2Care stations effectively around lake properties and who follows all product guidelines for use near the water.
Creating a "No-Fly Zone" with Personal Protection
Sometimes, you just want to sit on the dock for an hour without a permanent installation. For these moments, we recommend a multi-layered approach.
- Fans: Mosquitoes are notoriously weak fliers. A simple high-velocity outdoor fan on your dock can create enough turbulence to keep them from landing.
- Thermocells: These portable devices create a 15-foot "protection bubble." They are scent-free and highly effective for stationary activities like fishing or dining on the dock.
- Professional Treatments: At TruServ Pest, we provide specialized dock services using eco-friendly, lake-safe treatments. Our targeted monthly programs are specifically designed to comply with Georgia’s unique waterway regulations, providing a safe and effective barrier against spiders and mosquitoes.

The Environmental Responsibility
Living on the lake comes with a responsibility to the environment. The Army Corps of Engineers has strict rules about what can be sprayed near the water. Always look for:
- Essential Oil Blends: Many modern pest control companies use peppermint, rosemary, and cedarwood oils. These are safe for aquatic life but highly irritating to spiders and mosquitoes.
- Biological Larvicides: "Mosquito Dunks" (Bti) are small donuts you can drop into any standing water. They kill mosquito larvae but are harmless to fish, birds, and humans.
Why Quality Matters
At TruServ Pest, we know trust is built through expertise. Whether you are a homeowner looking for the right pest control partner for your lake property or simply trying to protect your investment, details matter.
A "bug-free summer" isn't just about chemicals; it's about a comprehensive strategy of cleaning, lighting, and targeted treatments. By maintaining your boathouse, you’re not just protecting your investment, you’re protecting your summer.
Your Checklist for a Bug-Free Boathouse
To wrap up, here is your quick-start guide to a better summer on the lake:
- Swap the Bulbs: Change white dock lights to yellow LED bug lights.
- Clear the Gutters: Ensure the boathouse roof isn't holding water.
- Sweep Weekly: Use a duster to knock down any new webs.
- Check the Covers: Ensure boat covers are tight and not pooling water.
- Call a Pro: Schedule a specialized dock treatment before the July heat hits.
Lake life is too short to spend it inside behind a screen door. By taking a few proactive steps today, you can ensure that the only thing biting this summer is the fish!
