Ants in Florida That Sting
Florida's warm, humid climate makes it a haven for all types of ants. Over 285 ant species are found in the state. Most Florida ants play beneficial roles in the ecosystem. However, some species deliver painful stings that can cause allergic reactions in sensitive individuals. Here is an overview of the most common ants in Florida that sting:
Fire Ants
Fire ants are likely the most infamous stinging ants in Florida. There are two main species - the red imported fire ant and the black imported fire ant. Fire ants arrived from South America via cargo ships and have spread throughout the southern United States. Their mounds are found in fields, lawns, roadsides, and parks.
When threatened, fire ants bite with their jaws and then sting from their abdomens. Their stings inject alkaline venom that causes a burning sensation. Fire ant stings usually form small, fluid-filled pustules on the skin. Though painful, the stings are not typically dangerous except in those allergic to the venom.
Harvester Ants
There are several harvester ant species in Florida, but the red harvester ant is the most likely to sting humans. These large ants range from orange-red to dark reddish-brown. They nest in sandy areas and can inflict painful stings when provoked.
The venom from a harvester ant sting contains cytotoxic alkaloids that can damage tissue at the wound site. Stings usually form major pustules within a day. Though rare, some people may experience severe allergic reactions to harvester ant venom.
Pavement Ants
Pavement ants nest under stones, slabs, and other debris in urban environments. They are black or reddish brown. Workers range from 1/16 to 1/4 inches long. When pavement ants sting, they spray formic acid for defense instead of injecting venom.
The formic acid causes immediate pain and skin irritation. Pavement ant stings typically result in red bumps and blisters. Scratching can lead to secondary infections. For most people pavement ant stings are not medically significant.
Crazy Ants
Crazy ants are an invasive species from South America established in Florida. They earned their name from their quick, erratic movements. There are several species of crazy ants, but they all deliver formic acid spray stings similar to pavement ants.
The acid causes a fast-burning pain. Some crazy ant species are also capable of stinging multiple times in succession. Populations are mainly concentrated around human structures where food is abundant.
Acrobat Ants
Acrobat ants include several Crematogaster species found in Florida. They nest in trees and shrubs. When disturbed, acrobat ants sting repeatedly. They curve their heart-shaped abdomens forward to spray formic acid stings.
The small stings feel like sparks hitting the skin. Acrobat ants mainly cause problems for Florida fruit growers. But homeowners may inadvertently come into contact with them in gardens.
Signs and Symptoms of Ant Stings
Ant stings share some common symptoms but also vary depending on the species. Typical signs include:
Sharp Pain
Most ant stings hurt right away. The pain may be instant and intense, especially from species like fire ants. Other ants cause milder burning or stinging sensations.
Skin Lesions
Venom and acid stings frequently cause visible skin reactions. Small red bumps, blisters, pimples, and white fluid-filled pustules often form.
Itching and Swelling
The sting site may itch and swell. Swelling ranges from slightly enlarged bumps to large, fluid-filled welts. Swelling often increases for the first 24 hours after a sting.
Possible Systemic Effects
In those allergic to ant venom, body-wide reactions can occur. Symptoms may include hives, itchy rashes, swollen lips or throat, breathing difficulty, dizziness, nausea, and an elevated heart rate.
Treating Ant Stings
Most minor ant stings can be treated at home. But large local reactions or systemic allergic symptoms may require medical evaluation. Here is how to treat ant stings:
Remove the Stinger
If a visible stinger remains in the wound, remove it carefully with tweezers. Avoid squeezing the venom sac if possible.
Clean the Area
Wash the sting with soap and water to remove antigens and prevent infection. Do not rub or scratch the sting site.
Apply Ice
Cold compresses, ice packs, or cold water ease pain and reduce swelling and itching. Apply for 10 minutes several times a day.
Use Anti-itch Creams
Hydrocortisone cream or antihistamines like diphenhydramine provide relief from itching.
Take Over-the-Counter Medications
Anti-inflammatories like acetaminophen, ibuprofen, or naproxen sodium can help reduce pain. Oral antihistamines treat itching and allergic reactions.
Use Home Remedies
Natural remedies like calamine lotion, baking soda paste, or aloe vera gel may soothe stings.
Consider Antibiotics
Topical or oral antibiotics treat secondary infections if pus or oozing develops. See a doctor for evaluation.
Preventing Ant Stings in Florida
The best way to avoid ant stings is to limit contact with them. Here are some tips for sting prevention:
Wear Protective Clothing
Wear shoes, socks, long pants, and sleeves outdoors where ants are active. Tuck pant legs into socks.
Watch Your Step
Be careful walking areas where ants build mounds and nests. Avoid stepping directly on colonies.
Keep Food Sealed
Store all food in sealed containers so it does not attract ants indoors or outdoors.
Use Caution Gardening
Inspect plants for ants before trimming or pruning them. Wear gloves to protect hands.
Treat Ant Mounds
Use boiling water, drenches of diluted dish soap, or pesticides to eradicate outdoor ant nests on your property.
Seal Home Entry Points
Repair cracks in foundations, install door sweeps, and caulk openings so ants cannot enter your home.
Keep the Lawn Short
Mow grass frequently and keep landscaping trimmed back since ants prefer areas with taller vegetation.
When to Seek Medical Care
In most cases ant stings can be treated at home without complications. But contact a doctor if you experience (14):
- Signs of anaphylaxis like trouble breathing, dizziness or throat swelling
- Stings inside the mouth or throat
- Extensive swelling beyond the sting site
- Stings to the eye area
- Severe pain that medication does not relieve
- Increased heart rate, headache, nausea or diarrhea
- Pus, oozing or red streaks indicating infection
- Persistent symptoms beyond a few days
People with histories of severe allergies or anaphylaxis should seek immediate medical care for any ant stings. Ant stings can be avoided with preventative measures. But prompt treatment provides relief if stings do occur.
