South Florida may have more ant species per square block than anywhere else in the continental United States, and Fort Lauderdale is a showcase. Many are nonnative species that arrived in cargo and thrive in warm, wet conditions. If trails are crossing your counters or mounds are popping up in your yard, call (844) 725-1661. PestMinistry connects callers with independent, licensed providers; we are a referral service and do not apply treatments ourselves.
The ants behind most calls
- Ghost ants: tiny with pale legs and abdomen, hard to see, nesting in potted plants, wall voids and under fallen leaves. They like sweets.
- White-footed ants: black with pale feet, forming very large colonies in trees and palms and sending trails along fences and walls.
- Bigheaded ants: they build soil tunnels along sidewalks and under slabs and can appear in huge numbers.
- Tawny crazy ants: reddish-brown and erratic, sometimes infesting electrical equipment.
- Red imported fire ants: mound builders in lawns, and their stings are painful.
- Carpenter ants: larger ants nesting in damp wood, often near leaks.
What makes the situation worse here
Constant warmth means colonies never go dormant. Palms, hedges and flowering shrubs in neighborhoods like Victoria Park, Lauderdale Isles and Wilton Manors give ants nesting sites and sap-feeding insects to farm for honeydew, which fuels bigger colonies. During heavy summer rains, flooded nests send the workers into houses. Ants in condo buildings can travel along shared pipes and electrical conduit, so one unit's problem becomes everyone's.
How professionals approach ants
- Identify: species determines the bait, since some ants prefer sugar and others protein or grease.
- Bait: slow-acting baits get carried back to the colony, which is the only reliable way to reach the queens.
- Barrier: a non-repellent exterior treatment around doors, windows and foundation.
- Landscape work: trimming plants off the house and controlling honeydew-producing insects like aphids and scale.
- Fire ant control: broadcast bait for the yard and treatment of individual mounds.
Contact sprays kill workers on sight but leave the nest intact, and some species respond by splitting into multiple colonies.
Do-it-yourself steps that actually help
- Wipe counters daily, and store honey, sugar and syrups in sealed containers.
- Do not leave pet bowls out overnight.
- Keep branches and vines from touching the roof and walls.
- Fix leaky irrigation heads and hose bibs.
- Caulk gaps where cables and pipes enter the house.
When to call quickly
Call promptly for fire ants near children and pets, for ants inside electrical panels or air conditioning equipment, and for carpenter ants, which may signal moisture damage. A repeated reappearance of ants after you have cleaned and sprayed is also a clue that the nest is in a wall or tree.
Ants and your yard
Many Fort Lauderdale ant problems start outdoors. Check potted plants and mulch beds for nests, and look up into palm crowns and hedges where trails often begin. Moving the pots off the lanai floor, raising mulch beds away from the slab and clearing leaf litter from window wells all remove convenient nesting sites. Reducing the sap-feeding insects on your ornamental plants cuts off the honeydew that fuels large colonies.
Fort Lauderdale yards with sprinklers on automatic timers may also be overwatered, which keeps soil soft for ground-nesting species.
