How to Get Rid of Crazy Ants in Florida

If you’re dealing with crazy ants in Florida, you know they’re not just another ant problem—they’re a full-blown invasion. Unlike fire ants or carpenter ants, crazy ants don’t build visible mounds. Instead, they nest in walls, electronics, and hidden crevices, making them hard to track and even harder to eliminate.

And the worst part? These relentless pests wreak havoc on electrical systems. Homeowners have reported fried circuit boards, shorted-out AC units, and even vehicle fires caused by crazy ant infestations.

You’ve probably already tried DIY sprays, ant baits, and pest control treatments—but if you’re still seeing swarms of ants, you know that traditional methods don’t work. Why? Because crazy ants require a very specific, multi-step control strategy to eliminate the entire colony and prevent future invasions.

This guide will break down how to identify, eliminate, and prevent crazy ant infestations in Florida—once and for all.

What Are Crazy Ants? (And Why They’re Worse Than Other Ants in Florida)

Crazy ants aren’t just another household pest—they’re one of the most aggressive and destructive invasive ant species in Florida. Unlike fire ants, which build visible mounds, or carpenter ants, which tunnel into wood, crazy ants prefer hidden nesting sites and spread rapidly, making them one of the hardest infestations to eliminate.

How to Identify Crazy Ants

If you’re wondering whether you’re dealing with crazy ants, here’s what sets them apart:

✅ Erratic, fast movements – Unlike other ants that march in predictable trails, crazy ants zigzag frantically, making them difficult to track.
✅ Long legs and antennae – Their bodies are slimmer and more elongated than fire ants or sugar ants, with noticeably long legs and antennae.
✅ No visible mounds – Crazy ants don’t build large dirt mounds, making their nests much harder to locate. Instead, they hide in walls, under debris, inside electronics, and even in vehicles.
✅ Massive colony sizes – While a fire ant mound may contain tens of thousands of ants, crazy ant colonies can reach billions per acre, spreading far beyond your property.

Not So Fun Fact: Crazy ant colonies are highly mobile and can spread up to 5 miles from their original nest—meaning if your neighbor has an infestation, your home could be next.

Why Are Crazy Ants So Hard to Kill?

Even homeowners who have successfully eliminated fire ants or other pests often struggle to get rid of crazy ants. Here’s why:

🚫 They ignore traditional ant baits – Many DIY solutions, including common ant gels and bait traps, simply don’t work on crazy ants. Their dietary needs shift frequently, making standard baiting strategies ineffective.
🚫 Killing them makes it worse – When crushed or sprayed, crazy ants release a pheromone that attracts even more ants, triggering an explosion in their population.
🚫 They invade electrical systems – Crazy ants actively seek out electronics, leading to shorted-out air conditioning units, fried circuit boards, and even car fires. Some infestations have caused thousands of dollars in damage.
🚫 Colonies have multiple queens – Unlike some ant species that rely on a single queen, crazy ant colonies contain multiple queens, meaning they reproduce at an alarming rate and can recover quickly even after partial extermination.

Because of these challenges, traditional ant control techniques won’t work. You’ll need a specific, multi-step approach to eliminate them completely. Keep reading to find out exactly what to do.

Step-by-Step Guide to Eliminating Crazy Ants in Florida

Eliminating crazy ants isn’t as simple as spraying insecticide and hoping for the best. Because of their massive colony sizes, multiple queens, and unpredictable movement, you need a strategic, multi-step approach.

Step 1 - Find and Eliminate the Colony

Before you can get rid of crazy ants, you need to track their nesting sites. Unlike other ant species, crazy ants don’t build visible mounds, so you’ll have to look in less obvious locations:

🔍 Where to Search for Crazy Ant Nests

If they haven’t already found you, you can look in these places:

✔️ Under rocks, woodpiles, and mulch
✔️ Inside walls, crawl spaces, and electrical outlets
✔️ In damp areas like leaky pipes, HVAC systems, or near standing water
✔️ Under appliances, furniture, and cluttered storage spaces

💡 Pro Tip: Since crazy ants forage long distances from their nests, their trails can be tricky to follow. To help pinpoint the colony, use bait traps to attract worker ants and track where they go.

Use Sweet and Protein Baits to Locate Their Trails

Crazy ants switch between sugar and protein diets, so setting multiple bait options increases your chances of success:

🍯 Sweet bait (for sugar cycle): Honey, jelly, or syrup
🥜 Protein bait (for protein cycle): Peanut butter, tuna, or raw meat

Place small amounts near suspected trails and check where they’re carrying the bait—it will lead you back to the nest.

Do Ultrasonic Pest Repellers Work Against Crazy Ants?

🚫 No. Unlike rodents or other pests that rely on sound-based communication, crazy ants are not affected by ultrasonic or light-based repellers. These products won’t stop them from invading your home.

Once you’ve identified the colony’s location, the next step is choosing the right treatment method to wipe them out at the source. Let’s break it down in Step 2.

Step 2 - Use the Right Ant Baits (Not Just Any Bait!)

Crazy ants are not like other ants when it comes to baiting. Many homeowners fail to control them because they use the wrong bait at the wrong time. These ants switch between sugar and protein diets depending on colony needs, so a one-size-fits-all approach won’t work.

Best Baits for Crazy Ants

✅ Protein Cycle: Use Invict Blitz when crazy ants are seeking protein.
✅ Sugar Cycle: Use Advion Ant Bait Gel when they are focused on sugar.

🔄 Pro Tip: Rotate between baits based on their feeding cycle. If you set out a sugar-based bait and ants ignore it, switch to a protein bait instead.

How to Apply Ant Baits Correctly

✔️ Place baits along foraging trails where ants are actively traveling.
✔️ Do NOT spray repellent insecticides near baits—this can make ants avoid the area.
✔️ Be patient. It can take several days for the bait to spread through the colony.

Once the bait is in place, it’s time to apply the right insecticides to target the entire colony.

Step 3 - Apply Non-Repellent Insecticides (Repellents Make It Worse!)

Many homeowners make the critical mistake of using repellent sprays like Raid or permethrin. These products scatter the colony, making the problem even more sinister.

Why Use Non-Repellent Insecticides?

🚫 Repellent sprays (like permethrin or pyrethroids) cause the ants to scatter, making them harder to control.
✅ Non-repellent sprays (like Taurus SC or FUSE) don’t alert the ants, allowing them to spread the insecticide to the entire colony through grooming and feeding.

Best Non-Repellent Insecticides for Crazy Ants

✔️ Taurus SC – A powerful non-repellent that kills ants slowly, allowing it to spread through the colony.
✔️ FUSE – A combination product that works similarly to Taurus SC but includes an extra active ingredient for long-term control.

How to Apply Insecticides for Maximum Effect

✔️ Spray Taurus SC or FUSE around the entire perimeter of your home, about one foot up and one foot out from the foundation.
✔️ Don’t spray directly on active ant trails—let the ants carry bait back to the nest first.
✔️ Apply insecticides twice a year for ongoing prevention.

By combining strategic baiting with non-repellent insecticides, you’ll wipe out the colony at its source instead of just killing a few worker ants.

Now, let’s talk about sealing entry points and controlling moisture to keep crazy ants from coming back.

Step 4 - Seal Entry Points and Control Moisture

Eliminating a crazy ant infestation is only half the battle—keeping them from coming back is just as important. Since crazy ants don’t build mounds and travel long distances to forage, sealing off their entry points and eliminating moisture sources will make your home far less inviting to them.

How to Keep Crazy Ants Out of Your Home

✔️ Seal cracks and crevices – Use caulk or weather stripping to seal gaps around windows, doors, baseboards, and foundation cracks. Even the smallest openings can be an entryway for these tiny invaders.
✔️ Check electrical outlets and utility openings – Crazy ants love nesting in electrical systems. Use sealant or foam around wires, pipes, and cable entry points.
✔️ Eliminate excess moisture – Crazy ants thrive in humid conditions. Reduce their preferred environment by:

• Fixing leaky pipes and faucets

• Running a dehumidifier in damp areas like basements and crawl spaces

• Ensuring gutters and downspouts properly drain away from your home

💡 Pro Tip: Since crazy ants don’t rely on a central nest, they often relocate quickly. Sealing entry points forces them to move elsewhere, reducing the chances of reinfestation.

Step 5 - Professional Help (When DIY Isn’t Enough)

For some homeowners, DIY treatments only offer temporary relief. If you’ve tried everything and the ants keep coming back within weeks, it may be time to call in the experts.

When to Call a Professional Exterminator

❌ If you’ve been battling crazy ants for months (or years) without success
❌ If you notice ants inside electrical systems, appliances, or your vehicle
❌ If your infestation covers a large area (inside and outside the home)
❌ If baiting and insecticides only seem to slow them down

What to Expect from Professional Treatment

📌 Cost: Expect to pay $1,500 or more, depending on the severity of the infestation​.
📌 Effectiveness: Some homeowners report that even professional treatments only last 3 weeks before ants return​.
📌 Long-Term Plans: Many pest control companies offer ongoing service contracts to prevent reinfestations throughout the year​.

At Hoffer Pest Solutions, we specialize in long-term crazy ant control using industry-proven techniques tailored to Florida’s climate. If DIY treatments aren’t cutting it, our experts can implement a customized plan to keep crazy ants permanently out of your home.

Why Do Crazy Ants Keep Coming Back? (And How to Stop It)

Many homeowners battling crazy ants feel like they’re stuck in an endless cycle—just when they think they’ve won, the ants reappear within weeks. This isn’t just bad luck—crazy ants are biologically wired to survive even the most aggressive pest control efforts.

Here’s why they keep coming back—and what you need to do differently to stop them for good.

Why Crazy Ant Infestations Are So Persistent

🚨 Killing them can make it worse – When crazy ants die, they release an alarm pheromone that signals more ants to swarm the area​.
🏠 They nest in hidden locations – Unlike fire ants, crazy ants don’t rely on a single mound. They spread out across walls, appliances, crawl spaces, and even vehicles​.
👑 Multiple queens mean fast regrowth – Even if you eliminate thousands of ants, a colony with multiple egg-laying queens can bounce back in days​.
⚡ They seek out electrical systems – If you’re not treating inside outlets, HVAC units, and appliances, you’re leaving a key part of the infestation untouched​.

The Biggest Mistakes Homeowners Make

Even well-intentioned efforts to get rid of crazy ants can backfire if you’re using the wrong approach. Avoid these common mistakes:

🚫 Using cheap store-bought sprays

Products like Raid or permethrin-based insecticides repel ants but don’t kill the colony. This just scatters them to new areas of your home.

✅ Instead: Use non-repellent insecticides like Taurus SC or FUSE to allow ants to spread the toxin throughout the colony​.

🚫 Overusing pesticides, creating “dead zones”

Spraying too much insecticide in one area creates a pesticide-free buffer zone, forcing ants to move their colony elsewhere—often deeper inside your home.

✅ Instead: Apply targeted treatments along foraging trails and entry points while letting baits do most of the work​.

🚫 Ignoring electronic infestations

Crazy ants love nesting inside electrical boxes, appliances, and even vehicles. If you only treat baseboards and foundations, you’re missing major infestation points.

✅ Instead: Inspect outlets, HVAC systems, and wiring for activity. If needed, use insecticidal dusts like Cimexa inside electrical boxes (but turn off the power first!)​.
