Welcome toNuisance Wildlife
Florida is famous for its sunshine, beaches, and abundant wildlife. Among the most common sights crawling around patios, climbing trees, or basking in the heat are lizards. But as their presence becomes more noticeable, especially in urban areas, many people wonder: Are Florida lizards poisonous? Are they dangerous to pets or humans? And if you’re dealing with a lizard infestation, what should you know before calling wildlife control?
Let’s dive into what’s fact, what’s myth, and what’s crawling around your backyard.
Here’s the short answer: Most lizards in Florida are neither poisonous nor venomous to humans.
But let’s break that down a bit. A poisonous animal releases toxins when you touch or eat it. A venomous animal, on the other hand, injects toxins through bites or stings.
In Florida, there are no native lizard species that are venomous or poisonous to humans. That said, some can bite, scratch, or carry bacteria that may cause infections.
Florida is home to several species of native and invasive lizards. Some are harmless. Others are aggressive nuisances that disrupt the ecosystem—or your backyard.
The brown anole is common in Florida. Some characteristics include:
While green anoles are native, they have become less common than brown ones. Ley characteristics include:
Knight anoles are less common than other types; however, they can cause some harm. The main characteristics of these lizards include:
It’s possible to find green iguanas in Florida due to the pet trade. Their key characteristics include:
You can find tokay geckos in Florida. They are not a native species. Key characteristics include:
While less common, it is possible to spot a Nile monitor while you are in Florida. They are an invasive species that can pack a huge punch. Key characteristics include:
Tegus are invasive in Florida. They have black and white spots or stripes with varying amounts of other colors. Their common characteristics include:
You may have heard of the Gila monster (Heloderma suspectum) and the beaded lizard (Heloderma horridum)—two well-known venomous lizards. But here’s the catch:
They don’t live in Florida.
These reptiles are found in the southwestern U.S. and Mexico, particularly in New Mexico, Arizona, and parts of Mexico. So while they’re important in lizard lore, they don’t pose a threat in South Florida or anywhere else in the state.
Most lizard bites in Florida are minor. However, they can still:
Signs of an infection after a lizard bite include:
If bitten, wash the area thoroughly and monitor for signs of infection. Medical attention may be necessary for deeper bites or signs of bacterial transmission.
Generally, lizards are shy and try to escape human contact. They’re more of a nuisance than a danger. But here are a few exceptions:
If you have lizards all over your yard or home, you might be wondering how to get rid of them. At Nuisance Wildlife Rangers, we offer humane lizard control so you can keep your family safe without harming animals in the process.
While most lizards don’t harm humans, many are harmful to Florida’s environment.
Invasive species like:
… are displacing native species, damaging infrastructure, and even preying on native birds, fish, and mammals. For instance, Nile monitors have been known to eat small turtles, snakes, and eggs from native nesting sites.
These reptiles thrive in Florida’s warm climate and multiply quickly, leading to overpopulation in certain areas.
If you’re noticing more lizards than usual around your property, you’re not alone. Lizards are a common sight in Florida, especially in South Florida, where the climate and vegetation support rapid population growth.
Here’s how to keep lizards out of your home and yard:
So, are Florida lizards poisonous? No. But some can be aggressive, carry bacteria, or cause environmental damage.
While most of these reptiles are interesting creatures and even helpful in eating insects, others, like iguanas, Nile monitors, and tegus, are a growing threat to Florida’s delicate ecosystems.
If you’re concerned about a lizard problem—whether it’s a nuisance around your yard or a full-blown infestation—it’s smart to call a licensed wildlife removal expert. Don’t attempt to catch large or aggressive lizards on your own. Between their sharp claws, sharp teeth, and high mobility, you could end up hurt—or worse, in a viral TikTok gone wrong.
Instead of DIYing lizard control, contact Nuisance Wildlife Rangers. We can trap and remove lizards without harming them in the process. Contact us today for more information on how to get started.
While lizards themselves don’t chew through materials like rodents, larger species—especially green iguanas—can dig extensive burrows. These tunnels may undermine foundations, sea walls, or sidewalks, leading to costly repairs. Iguanas have been linked to erosion along canal banks in South Florida.
Yes. Lizards are particularly drawn to dense foliage, fruit-bearing plants, and mulch beds, which offer cover and attract the insects they feed on. Palms, hibiscus, and tropical ornamentals are common lizard-friendly choices in Florida yards.
Most lizards are silent, but a few species like the tokay gecko emit loud vocalizations—a distinct “tokay, tokay” sound—especially at night. These calls can be startling and are often mistaken for bird or frog noises.
For common species like green anoles or brown anoles, non-lethal removal is legal. However, for invasive or regulated species such as green iguanas, Nile monitors, and tegus, Florida law requires humane euthanasia if captured. It’s best to consult with or hire a licensed wildlife removal professional to ensure legal compliance and humane treatment.
Lizard eggs are usually small, white, and soft-shelled, laid in soil, mulch, or hidden crevices. While native species pose no threat, invasive lizard eggs contribute to overpopulation. Avoid handling them directly. If you suspect they belong to an invasive species, contact your local wildlife control agency or pest management provider for next steps.
Not exactly. Lizards in Florida slow down in colder months, especially in northern areas, but don’t fully hibernate. Instead, they enter a semi-dormant state called brumation. In South Florida, many remain active year-round due to the warm climate.
