Ant Spotlight: Caribbean Crazy Ants

Caribbean Crazy Ants

Originally thought to be Paratrechina pubens, an ant from the Lesser Antilles that were imported in shipping containers to South Florida’s shores in the 1950s, the large populations of crazy ants found in Florida in the 1990s were a slightly different species called Nylanderia fulva, the tawny crazy ant, whose point of origin is actually Brazil. Introduced to Colombia in the 30s and 40s as a biological control for leaf-cutting ants and poisonous snakes, according to a 2012 University of Florida IFAS article, tawny crazy ants are on the rise in “24 counties in Florida: Alachua, Brevard, Broward, Clay, Collier, DeSoto, Duval, Hardee, Hillsborough, Indian River, Lee, Manatee, Marion, Martin, Miami-Dade, Orange, Palm Beach, Pasco, Pinellas, Polk, Saint Johns, Saint Lucie, and Sarasota.”

Small, reddish-brown ants get their names from their erratic actions

Not a large ant, by any means, compared to the reigning invasive ant species in the Southeast, the formidable, South American fire ant, these small, 1/8-inch, hairy, reddish-brown ants with ridiculously long antennae and legs behave in some, well . . . crazy ways.

Moving rapidly along dense foraging trails, Caribbean crazy ants seem to break into their own samba interpretations, dashing madly about in all directions when disturbed, possibly in pursuit of a dance partner. All kidding aside, like many invasive species, crazy ant populations contain multiple queens in order to accelerate population growth. Crazy ant populations number in the millions, with infestations described as ants, “blanketing yards and sidewalks.” Also, known to overcome small animals and livestock, crazy ants lodge in the nostrils of animals, asphyxiating newborn livestock. With one population of crazy ants in the millions, these colonies consist of a network of nests that make these ants impossible to control by homeowners with commercially available products.

Adaptable and resistant to fire ants, crazy ants can cause a lot of damage

Incredibly adaptable to areas with high moisture conditions, like South Florida, crazy ants can also survive in drier conditions, which is why their cousin, the Rasberry crazy ant has been spotted marauding around Texas, along with the longhorn crazy ant. In the Southeast, crazy ants are overtaking South American fire ants, causing a disruption in ecosystems. While the dreaded fire ant’s venom packs a powerful punch to humans and animals, this invasive species builds noticeable mounds in your backyard and only attack humans and pets, when provoked.

Crazy ants might make you miss your aloof fire ant neighbors

Interestingly, crazy ants, originating from the same area of the globe as fire ants, secrete venom that acts as an antidote to fire ant venom. This peculiar adaptation allows the smaller, crazy ants to triumph over larger, more venomous fire ants.

Crazy ants, with an appetite for honeydew, produced by aphids and scale insects, move the aphids from infested plants to healthy plants, in order to enjoy the honeydew. This activity can decimate agricultural crops and eliminate insects that are attracted to crops, drastically reducing food sources for birds and other animal life that rely on insects as food sources. Crazy ants will feed on dead insects as well as rabbits, lizards and other small animals.

Crazy ants invade your electric circuits

Additionally, while fire ants generally keep to themselves in large, visible mounds in your backyard, crazy ants don’t mind invading your home, jamming your electronics and causing shortages in your electrical circuits. Not the only ants to be attracted to electrical currents or warm, enclosed spaces, such as switch boxes and electrical plates, crazy ants fired up by electricity send out attack signals to their colonies, causing a pile up of crazy ants answering the call to battle. As crazy ant carcasses pile up, circuits jam and electrical failures occur. While crazy ants pose no direct health threats to humans, they cause frustrating power failures and annoying cleaning situations.

South Florida residents need to contact a trusted pest control professional to eliminate crazy ant infestations

South Florida residents can help prevent crazy ants by taking a few common-sense steps but attempts to eliminate crazy ant infestations should be handled by a professional pest control company, such as locally owned and operated, Hulett Environmental Services.

Prevention tips include:

  • Removing yard debris and clutter that provide shelter for insects.
  • Repairing any pipes, spouts and faucets that leak water necessary to crazy ant survival.
  • Minimizing standing water on your property, including flowerpots and animal water bowls.
  • Check your property for established colonies. Crazy ants don’t build mounds, so you will likely notice thick, golden-brown ant trails on structures, on vegetation or erratically darting around on the ground.

Caribbean Crazy Ants

What are crazy, hairy ants? Are they referred to as Rasberry Crazy Ants or Caribbean Crazy Ants?

  • These are probably all one and the same species Nylanderia pubens with multiple common names.
  • Rasberry crazy ants were first found in Texas in 2002. They are believed to be related to a species from the Caribbean.
  • Caribbean crazy ants are found in Florida – have likely been there since the 1950’s but pest professionals have been receiving more and more reports since 2000.
  • The more common Crazy ant (Paratrechina longicornis) looks similar to the Rasberry and Caribbean crazy ants, but have marked differences. Their antennae and legs are significantly longer and their bodies are slightly larger. Their populations are also more spread out around the U.S.

Crazy ants get their common name from their habit of running in an erratic, jerky manner when searching for food.

Crazy, hairy ants are an invasive species by definition so are very good at invading new areas. Ants react to drought and rainfall in different ways so weather can play a role in their movement. Additionally, they  are very good hitchhikers and can be transported to new areas as stowaways in cargo.

In the U.S. these ants are found in South Florida, Louisiana, Mississippi, Houston and surrounding areas of coastal Texas.

Specifically for Texas, according to Texas A&M University’s Center for Urban & Structural Entomology, “high numbers of the ants have been found in localized spot infestations in southeast Houston (Harris County), including Houston, Pasadena, Deer Park, Friendswood, San Jacinto Port, Pearland, Seabrook and La Porte. Localized infestations have also been confirmed from areas in Bexar, Brazoria, Cameron, Fort Bend, Chambers, Galveston, Hardin, Harris, Hidalgo, Jefferson, Jim Hogg, Liberty, Matagorda, Montgomery, Nueces, Orange, Walker and Wharton counties. This ant has the potential to spread well beyond the current range in coastal Texas.”

These ants prefer tropical/semi-tropical climates.  Colonies typically grow in warmer months with populations peaking in August/September. Their numbers remain high through October and November.

Although these ants usually nest outside, they will forage indoors in large numbers in cooler temperatures or after rainfall. Inside, crazy ants usually nest underneath floors or carpeting, inside wall voids and soffits.

Crazy ants can become a problem when they infest a home or another structure for a couple of reasons:

  • Extremely large colonies resulting in massive infestations which can be difficult to treat, often requiring multiple treatments.  Colonies may grow to about 1 million.
  • These ants also have an odd propensity to nest in electrical boxes and around electrical equipment, causing short – outs and electrical equipment failure.
