    How to Get Rid of Palmetto Bugs in Florida

    Updated January 2025 · 8 min read

    If you live in Brevard County, you've met the palmetto bug. These large, fast-moving cockroaches are one of Florida's most common — and most despised — household pests. Whether they're scurrying across your kitchen floor at midnight or flying toward you on a humid evening, palmetto bugs are a fact of life in Melbourne, Palm Bay, Cocoa, and every other Space Coast community.

    But that doesn't mean you have to live with them. Here's everything you need to know about getting palmetto bugs out of your home and keeping them out.

    What Exactly Are Palmetto Bugs?

    The term "palmetto bug" typically refers to the American cockroach (Periplaneta americana), though Floridians also use it for smoky brown cockroaches and Florida woods cockroaches. These insects are 1.5 to 2 inches long, reddish-brown, and — unlike their German cockroach cousins — they primarily live outdoors in mulch, palm trees, and leaf litter. They enter your home looking for moisture and shelter, especially during heavy rains or extreme heat.

    Why Brevard County Has So Many Palmetto Bugs

    Brevard County's subtropical climate creates ideal conditions for palmetto bugs year-round. High humidity, warm temperatures, abundant vegetation, and proximity to water (the Indian River Lagoon, the St. Johns River, and the Atlantic) all contribute to thriving populations. Homes near wooded areas in Titusville, properties along the waterways in Merritt Island, and suburban developments in Viera and Rockledge all experience palmetto bug pressure.

    5 Proven Methods to Eliminate Palmetto Bugs

    1. Seal Entry Points

    Inspect door sweeps, window screens, plumbing penetrations, and foundation cracks. Palmetto bugs can squeeze through gaps as small as 1/4 inch. Use silicone caulk for small gaps and steel wool plus expanding foam for larger openings around pipes.

    2. Eliminate Moisture Sources

    Fix leaky faucets, ensure proper drainage around your foundation, and use dehumidifiers in bathrooms and laundry rooms. Palmetto bugs need moisture to survive — removing water sources makes your home far less attractive.

    3. Remove Outdoor Harborages

    Keep mulch beds at least 12 inches from your foundation. Trim palm fronds and vegetation touching the house. Remove leaf litter, woodpiles, and debris near exterior walls. These are palmetto bug highways into your home.

    4. Use Targeted Baits and Residual Sprays

    Gel baits placed in cracks and crevices attract and kill roaches at the colony level. Residual perimeter sprays create a chemical barrier around your home's exterior. For best results, reapply every 90 days — especially in Florida's rainy season when products wash away faster.

    5. Schedule Professional Quarterly Treatments

    DIY methods help, but professional pest control provides the most reliable long-term solution. A licensed technician can identify entry points you'd miss, apply commercial-grade products, and create a treatment schedule tailored to your property's specific pest pressure.

    When to Call a Professional

    Seeing an occasional palmetto bug near your patio door is normal in Florida. But if you're finding them regularly indoors, spotting small ones (which indicates breeding inside your walls), or noticing droppings in cabinets and drawers, it's time for professional treatment. German cockroaches in particular reproduce rapidly and are resistant to many over-the-counter products.

    At 321 Pest Control, we serve homeowners throughout Brevard County with targeted roach treatments that include interior crack-and-crevice applications, exterior perimeter barriers, de-webbing, and harborage elimination. Our quarterly plans keep palmetto bugs out year-round — guaranteed.
