Florida lizards are a common sight. While some can bite, incidents are rare and not a significant threat to humans. Most bites occur as a defensive response when lizards feel threatened, are cornered, or mishandled.
Biting Habits of Florida Lizards
Lizard bite severity depends on the species. Smaller, common lizards like green and brown anoles rarely bite humans. Anole bites are typically weak, not breaking the skin and causing minimal pain. Anoles are insectivores, biting only in self-defense.
Larger, non-native species possess greater biting capability. Green iguanas, with sharp, serrated teeth, can inflict painful, damaging bites. Their bites can lead to lacerations and puncture wounds; they also use powerful tails and claws for defense.
The Argentine black and white tegu, an invasive species, grows large and has strong jaws capable of a bite force around 220 pounds per square inch, powerful enough to crush human fingers. Tegus defend aggressively.
Similarly, Nile monitor lizards, also invasive, are not venomous but can deliver a nasty bite. Their saliva might contain harmful bacteria.
The Nature of Lizard Bites
No native Florida lizard species are venomous. No venomous lizards like the Gila monster are found in Florida. A typical lizard bite from common Florida species is usually a pinch or shallow tear.
Lizard bite concerns include localized pain, superficial skin breaks, and infection risk. Lizards carry bacteria in their mouths, including Salmonella, which can be transmitted through a bite. Bites from smaller lizards often do not penetrate the skin, but larger species can cause deeper wounds requiring more attention. Proper care prevents complications from bacterial exposure.
What to Do After a Lizard Bite
Immediate first aid after a lizard bite reduces infection risk. Thoroughly wash the wound with soap and warm water to remove bacteria or debris. Apply an antiseptic solution or ointment and cover with a clean bandage.
Monitor the wound for infection signs: increasing redness, swelling, warmth, pus, or worsening pain. Seek medical attention if the bite is deep, bleeding persists, or infection signs develop. For bites from larger, non-native species like a tegu or monitor lizard, professional medical evaluation is recommended due to potential for deeper wounds and harmful bacteria. Ensure your tetanus vaccination is up to date.
Preventing Lizard Encounters
Preventing lizard bites involves respecting their space and avoiding handling wild lizards, as most bites are defensive. Maintain a safe distance from any lizard, especially larger or unfamiliar species, to prevent defensive reactions.
Keeping outdoor areas tidy helps deter lizards. Remove brush piles, debris, and hiding spots to make your property less appealing. Avoid feeding wild lizards to reduce their presence and prevent them from associating humans with food. Sealing home entry points like cracks or gaps around doors and windows can also prevent lizards from entering.
