Name(Required)

Down here, it’s not unusual to see ants show up after a rainstorm, a few extra-humid days, or when the AC is running nonstop and there’s a little condensation somewhere. And if you’re near the water, with palms, mulch, and shaded areas around the home, ants have plenty of places to nest outside and plenty of reasons to come inside.

A lot of Key Largo ant problems start small: a few ants near the sink, a line heading toward the coffee bar, or tiny ants showing up around a trash can even though you just took it out. You clean, you spray, and it feels better for a minute… then they’re back, sometimes in a totally different room.

That’s because the ants you see are just the workers. The colony is usually tucked in mulch beds, under pavers, around roots, or in tiny gaps near the foundation. Eastern Exterminating helps Key Largo homeowners, vacation rental owners, and local businesses stop ant problems by handling the source, not just the trail.

Our Ant Control Process

Step

1

Inspection and Assessment


We start by figuring out what kind of ants you’re dealing with and what’s attracting them. In Key Largo, we typically check:



  • Kitchens and pantry zones (sugar, crumbs, pet food, trash areas)

  • Bathrooms and laundry spaces (moisture is a big driver in the Keys)

  • Window tracks, door thresholds, baseboards, and utility line gaps

  • Outdoor pressure points like patios, outdoor kitchens, planters, and mulch beds

  • Signs of nesting near pavers, under rock beds, or along the home’s perimeter


We’re looking for the “why” behind the trail, because that’s what makes the fix stick.

Step

2

Custom Treatment Plan


Key Largo properties come in all kinds of layouts, canal-front homes, neighborhoods tucked into the trees, rental properties with high turnover, and small businesses that need discreet service. Depending on what we find, your plan may include:



  • Targeted baiting (so workers take it back to the colony)

  • Spot treatments where activity is strongest (inside and outside)

  • A perimeter barrier to reduce re-entry and stop new trails

  • Practical prevention tips that make sense for your property (especially if it’s a rental)

Step

3

Full Extermination (Colony-Level Control)


We’re not aiming for “they’re gone for the weekend.” We focus on colony control, targeting nests and satellite colonies that keep activity going even when the visible ants disappear for a few days.

Step

4

Ongoing Monitoring and Prevention


In the Keys, pest pressure doesn’t really take a season off. If ants keep coming back, we can recommend ongoing protection that includes:



  • Follow-ups to confirm the issue is truly resolved

  • Extra attention to recurring entry zones

  • Long-term prevention strategies to reduce repeat trails

Why Ant Control Matters in Key Largo

Ants can turn into a repeat problem fast

Ants are persistent, especially when they’ve found moisture and food. Depending on the species, they can:

  • Get into pantry items and food-prep areas
  • Spread room-to-room along baseboards and plumbing lines
  • Bite or sting (outdoor activity can be a big issue)
  • Nest in hidden spaces that are hard to reach without the right treatment plan

If you’re seeing ants during the day, it usually means the colony is established and actively foraging.

Local relevance: common ant issues in the Key Largo area

The Keys’ humidity and landscaping make a few ant types especially common:

  • Ghost ants / sugar ants: tiny, sneaky, and usually show up in kitchens and bathrooms
  • Fire ants: typically outdoors; painful stings and yard activity around landscaping
  • Carpenter ants: attracted to moisture; can nest in damp or softened wood
  • Crazy ants: stubborn exterior infestations with messy, unpredictable trails

Why Choose Eastern Exterminating

We get the Keys environment

Key Largo is different than the mainland, more moisture, more outdoor living, and more places for pests to hide. We treat based on what actually works here, not a generic “one spray fits all” approach.

Licensed, professional treatments

We use targeted applications based on the species and the conditions around your home, so you’re not wasting time (or money) on the wrong approach.

Clear communication (especially helpful for rentals)

If this is a vacation rental or seasonal home, you need simple answers and a plan you can actually manage. We’ll explain what we found, what we’re doing, and how to reduce repeat issues moving forward.
