Seal Entry Points

  • Inspect your home for any potential entry points that crazy ants could use to gain access, such as wall voids.

  • Focus on sealing cracks in the foundation, gaps around windows and doors, and any other small openings you find in the baseboards.

  • Use silicone-based caulk or weather stripping to block these entrances effectively.

Maintain a Dry Landscape

  • Repair any leaky faucets, hoses, or irrigation systems promptly.

  • Ensure that your home's drainage systems are functioning correctly, directing water away from your house to prevent accumulation.

  • Consider landscaping options that promote good drainage and reduce moisture retention in soil near your home.

How to Get Rid of Crazy Ants in Florida

When addressing the control of crazy ants in Miami, FL, you may face a choice between professional pest management services and attempting do-it-yourself (DIY) solutions.

Immediate DIY Actions

  1. Seal entry points: Inspect your home for any cracks or crevices and seal them with silicone caulk to prevent ants from entering.

  2. Remove attractants: Keep your kitchen and dining areas clean. Store food sources in sealed containers and manage garbage regularly so as not to attract ants.

  3. Use natural deterrents: Apply vinegar, lemon juice, or peppermint oil around entry points. These natural repellents act as an insecticide that can deter ants without harming your family or pets.

Targeted DIY Solutions

  1. Boric acid bait: Mix boric acid with a sweet substance, like sugar water or honey, to attract and poison crazy ants. Place the ant bait near ant trails but out of reach of children and pets.

  2. Diatomaceous earth (DE): Sprinkle food-grade diatomaceous earth around the perimeter of your home. DE works as a desiccant, drying out the ants' exoskeletons and killing them.

  3. Soap and water spray: A mixture of soap and water can kill ants on contact. Spray it directly on ants and their pheromone trails to disrupt their pathfinding.

While DIY solutions often seem like a cost-saving measure, without proper knowledge and tools, they might be more expensive in the long run if the ant problem persists.

That’s where investing in a professional pest control company could result in more effective and sustainable management.
