Dangerous Florida Bugs That Humans Need To Avoid


Fire Ants: A Painful and Potentially Dangerous Sting


If you've spent any time outside in Florida, you've likely had an encounter with fire ants. These aggressive insects are notorious for their painful stings, so you'll want to steer clear of them. Fire ant mounds, which can reach up to 18 inches in height, are found throughout the state.


The fire ant's sting injects a toxin that causes a burning sensation, as the name implies. Their stings can lead to swelling, redness, and irritation that lasts up to 8 hours. For some people, especially children or those allergic to the venom, the stings may trigger a dangerous allergic reaction known as anaphylaxis. Seek medical help immediately if someone experiences nausea, vomiting, or difficulty breathing after a fire ant sting.


To avoid fire ant stings, watch out for mounds and nests in grassy, open areas like parks, gardens and playgrounds. Wear closed-toe shoes, especially in summer, and avoid direct contact with mounds. Never disturb an active mound. Fire ant stings are most likely to occur when the ants feel threatened or are defending their colony.


The best way to get rid of fire ants is by applying pesticides, known as ant baits or mound drenches. You can also use natural repellents like chili pepper, coffee grounds, lemon juice and eucalyptus oil around the house to deter fire ants in an eco-friendly manner. However, fire ants are notorious survivors. Often DIY pest control methods can cause fire ant colonies to multiply. To truly remove fire ants from your yard, call a professional pest control company like Super D Pest Control.


Mosquitoes: More Than Just an Itchy Nuisance


If you live in Florida, you know mosquitoes well. These blood-sucking insects aren't just annoying - they can transmit dangerous diseases like West Nile virus, Zika, and encephalitis.


Female mosquitoes are the ones that bite, needing the protein from blood to develop their eggs. They're most active at dawn and dusk, so that's when you'll want to be most vigilant. Some tips to avoid mosquito bites:


  • Wear insect repellant with DEET or oil of lemon eucalyptus, especially at peak biting times. Reapply every few hours.

  • Wear light-colored clothing, long sleeves and pants. Mosquitoes are more attracted to dark clothing.

  • Dump out any standing water on your property. Mosquitoes can breed in as little as one tablespoon of water. Clear your gutters, birdbaths, pet bowls, and buckets.

  • Install outdoor fans. Mosquitoes have a hard time flying in wind, so outdoor fans and misters can help keep them away from gatherings.

  • Repair any holes or tears in outdoor screens. Make sure all doors and windows close securely. The fewer entry points to your home, the better.


While mosquito bites are merely irritating for most, the diseases they carry are life-threatening. Take every precaution to safeguard yourself and your loved ones. The nuisance is minor, but the risks are not. Protecting against these dangerous insects is well worth the effort. Your health and safety should be the top priority.


Buck Moth Caterpillars: Toxic Spines Can Cause a Painful Rash


If you spot the furry brown caterpillars of the buck moth, be very careful! These little critters are covered in venomous spines that can inflict a painful rash if touched. Buck moth caterpillars, also known as wooly bears, are common in Florida and feed on plants like oak, willow, and maple trees.


When threatened, the buck moth caterpillar will rear up and flail its many spines. Each spine contains a toxin that may cause swelling, redness, and a burning sensation lasting up to 8 hours. The rash usually isn’t dangerous, though the pain can be intense. The spines can also become embedded in the skin, requiring tweezers to remove.


The best way to avoid a run-in with these toxic caterpillars is to be on alert for them, especially if you live near wooded or brushy areas. Buck moth caterpillars are most active from spring through fall. Look for wooly bear caterpillars crawling on the ground, plants, outdoor furniture, or any surface. Their furry brown bodies can be up to 2 inches long.


If you do get stung, immediately wash the area thoroughly with soap and water. Apply a cortisone cream to help with inflammation and itching. An oral antihistamine, like Benadryl, may also provide relief from discomfort. See a doctor for any signs of infection or a severe allergic reaction.


The good news is, the buck moth caterpillar will not attack humans aggressively or in swarms. They typically only sting in defense of being touched or handled. While the spines can be potent, the effects are usually localized and short-lived. With caution and awareness, Floridians can avoid the wrath of this fuzzy little creature.


Wasps: Aggressive Stinging Insects That Can Be Life-Threatening to Some


Wasps are aggressive stinging insects that can be life-threatening to some, especially those with allergies. Their painful stings should be avoided.


Appearance and Habitat


Wasps are social insects that live in colonies with a queen. They build paper nests, usually in sheltered areas like under eaves, inside wall voids or in the ground. Adult wasps are typically less than an inch long with yellow and black coloring.


It is important to note that not all wasps are harmful.


That being said, wasps tend to be more active and aggressive in late summer and fall when their colonies are largest. They become defensive of their nesting area and quick to sting in order to protect the colony.


Dangers and Health Risks


A normal wasp sting is painful but not usually dangerous for those without allergies. However, their stings can be life-threatening to the small percentage of people with allergies to their venom. Seek medical help immediately if someone experiences symptoms like swelling of the throat, tongue, lips or face, dizziness or difficulty breathing after a wasp sting.


For most, the area around the sting will swell, redden and itch. Applying a cold compress, oral antihistamines and hydrocortisone cream can help reduce discomfort. See a doctor for any signs of infection like pus, swelling beyond 2-3 days or severe pain.


Prevention and Control


The best way to avoid wasp stings is through prevention:


  • Avoid nesting areas, especially around dusk and dawn when wasps are most active.

  • Wear light-colored clothing, avoid fragrances and do not leave food or drink outside.

  • Install physical barriers like weatherstripping or mesh to block entry into homes.

  • If a nest is spotted, hire a professional to remove it rather than attempting to do it yourself.


To reduce wasp populations in the long run, practice good home maintenance like sealing up cracks leading into wall voids or attics where they may build nests. Work with pest control experts who can apply treatments targeting wasps for the most effective and long-lasting control. Staying informed and vigilant is key to avoiding these dangerous stinging insects in Florida.

Venomous Spiders: Beware of the Brown Recluse and Black Widow


Venomous spiders can deliver a nasty and even life-threatening bite, so be on the lookout for these dangerous arachnids in Florida. Two spiders in particular pose the biggest threat: the brown recluse and black widow.


Brown Recluse


The brown recluse spider is shy and rarely bites unless provoked. However, its venom is hemotoxic, meaning it destroys red blood cells and tissue. A brown recluse bite often goes unnoticed at first, but within several hours it can lead to severe pain, swelling, and blistering of the skin. Seek medical attention immediately if bitten, as necrosis (skin death) and scarring can occur. Brown recluse spiders build irregular webs in undisturbed areas like attics, basements, and sheds. They are most active at night, so be cautious when sorting through stored boxes or handling firewood.


Black Widow


Black widow spiders are perhaps the most infamous venomous spider in North America. The female black widow, with her distinctive red hourglass marking, has a potent venom that can cause a range of symptoms in humans including nausea, vomiting, chest pain, and difficulty breathing. While rare, black widow bites can also be fatal, especially to young children and the elderly. Black widows build messy webs under decks, in sheds, under outdoor furniture, and in other undisturbed places. Be very careful when clearing brush or debris, and always wear heavy gloves.


By exercising caution when in areas where these venomous spiders dwell, you can avoid a dangerous—and potentially deadly—encounter. Don't leave them to chance; if you spot webs or spiders that worry you, contact a professional exterminator to treat the area. Your safety is worth the investment.
