Identifying and Treating Florida's Most Common Bug Bites

Common Bug Bites in Florida

Florida's warm, humid climate makes it a haven for all types of bugs. With over 1,300 species of insects and arachnids calling Florida home, bug bites are a common occurrence for residents and visitors alike. While most bug bites only result in mild irritation, some can transmit serious diseases. Knowing how to identify different bug bites can help you seek appropriate treatment if needed.

Mosquito Bites

Mosquitos are likely the most infamous pests in Florida. Though their bites typically cause only minor swelling, redness and itchiness, mosquitos can transmit dangerous diseases like West Nile virus, Zika virus, malaria, and equine encephalitis.

To reduce mosquito bites, use insect repellent containing DEET when spending time outdoors, especially near bodies of water and at dusk when mosquitos are most active. Wear long sleeves and pants or treat your clothes with permethrin. Drain any standing water near your home where mosquitos breed.

Spider Bites

While the majority of spider species in Florida are harmless to humans, some do pack a venomous punch. Black widows, brown recluse spiders, hobo spiders and the aptly named banana spiders can deliver painful bites.

Black widow bites cause muscle cramps, nausea, and dizziness. Brown recluse bites can result in itchy blisters or ulcers. Seek medical care if you suspect you've been bitten by one of these venomous spiders.

Bed Bug Bites

Bed bugs have made a major resurgence in Florida homes, hotels and public spaces in recent years. These sneaky pests feed on human blood while people sleep. Their bites typically appear in clusters or lines on exposed skin.

Though not known to transmit disease, bed bug bites can cause severe allergic reactions in some people. Eliminating bed bugs requires professional pest control. To avoid bringing bed bugs home, thoroughly inspect hotel rooms before unpacking suitcases and wash all clothing immediately upon returning from travel.

Flea Bites

Fleas thrive in Florida's warm climate. People most often encounter fleas when interacting with wildlife or pets that harbor fleas outdoors. Flea bites typically occur around the legs and ankles, causing many small itchy spots likely with a red "bulls-eye"

Use flea control products on pets and treat your yard to eliminate flea infestations. Apply an antibiotic cream to bite sites that become infected. See your doctor if bites cause severe allergic reactions.

Chigger Bites

Commonly called red bugs, chiggers are mite larvae that feed on skin cells. They inhabit tall grasses and bushes where people may brush up against them. The microscopic chiggers crawl onto the body and inject enzymes that digest skin cells.

Their bites usually occur around the ankles, waistline and armpits. The bites appear as intense itchy, red welts. Over-the-counter steroid creams provide relief from itching and swelling. Avoid scratches as they can lead to infection.

Ant Bites and Stings

Florida hosts over 200 ant species, including fire ants which can deliver painful stings. Fire ant stings usually occur when accidentally stepping on a mound. A stinger on the ant's belly injects venom as it bites that raises itchy, burning welts.

Counteract the venom by washing the sting with soapy water and applying a cold pack. For severe reactions to fire ant stings, seek emergency care. Other ants like carpenter and harvester ants bite and spray acid but rarely require medical treatment beyond managing discomfort..

Stinging Caterpillars

Caterpillars of moths and butterflies thrive in Florida's sub-tropical climate. Though most species pose no danger, venomous spines on the bodies of buck moth and puss caterpillars can stick in your skin from the slightest touch.

The sting feels similar to a bee or wasp sting, with swelling, redness, headache, vomiting or rash possible. Use adhesive tape to remove any spines stuck in the skin to reduce venom release. Utilize an oral antihistamine for mild reactions or seek emergency care for severe reactions.

Kissing Bugs

Better known as assassin bugs, kissing bugs get their nickname from biting humans around their mouths or eyes. Kissing bugs feed on blood like mosquitos and can transmit Chagas disease. Bites may swell and become infected.

Chagas disease is a tropical illness that can damage the heart, esophagus and colon. Symptoms may not appear for decades after the bite. Talk to your doctor about testing if you suspect a kissing bug bite. Reducing hiding places like woodpiles around the home helps deter kissing bugs.

Treating Bug Bites

Most bug bites and stings in Florida only result in mild irritation for a day or two. Taking a few self-care steps provides relief:

• Wash the bite with soap and water.
• Apply a cold pack to reduce pain, swelling and itching.
• Use hydrocortisone cream to ease redness and itching.
• Bandage the bite site loosely to prevent infection.
• Take an oral antihistamine containing diphenhydramine (Benadryl) to reduce swelling.

Seek prompt medical care if you experience:

• Difficulty breathing
• Swelling in the throat
• Dizziness, chest pain or vomiting
• Blistering rash

Let your doctor know if the bite site shows signs of infection like pus, redness or heat. Infected bites may require antibiotic treatment.

Preventing Bug Bites

While avoiding all bug bites is nearly impossible in Florida, you can take precautions to reduce your risk:

• Use insect repellent containing 20%-30% DEET when spending time outside.
• Wear loose, long sleeve shirts and pants when hiking, camping or gardening.
• Treat clothes, tents and camping gear with 0.5% permethrin to repel insects.
• Avoid water sources and bodies; prime mosquito habitat.
• Stay away from tall grasses and shrubs where chiggers congregate.
• Apply pesticides around your home to control insects.
• Seal cracks and crevices where bugs enter buildings.
• Inspect furniture, bedding and luggage for signs of bed bugs during and after travel.
• Have pets on consistent flea and tick control medication.

Taking preventative and evasive actions goes a long way to avoiding bug bites. However, when spending time outdoors in Florida, the occasional mosquito bite or spider sting comes with the territory. Use the tips above to identify the culprit and treat the bite accordingly.
