Wild lizards can bite, though such incidents are generally uncommon. Most bites are minor, often resulting in small wounds. Understanding why a lizard might bite, how to respond, and when to seek medical attention can help prevent complications and ensure safety.
Why Lizards Bite
Lizards bite as a defensive measure when threatened or cornered. This is a natural self-preservation response, especially if they cannot escape. Bites often occur when people attempt to handle wild lizards. Sometimes, a lizard might bite due to mistaken identity, associating human fingers with food, particularly if accustomed to hand-feeding. Larger species like monitor lizards or iguanas can deliver more forceful bites than smaller garden lizards.
If You Are Bitten
If bitten by a wild lizard, immediately clean the affected area thoroughly with soap and warm water. After cleaning, apply an antiseptic solution or ointment. Covering the wound with a clean bandage is also advisable to protect it.
Lizards can carry bacteria, including Salmonella, which may lead to infection. Monitor the wound closely for signs of infection, such as increased redness, warmth, swelling, pus, worsening pain, or fever.
Most lizards are not venomous. The Gila monster and Mexican beaded lizard are the only known venomous species. They are found primarily in the southwestern United States and parts of Mexico and have distinct appearances. Their venom can be painful but is rarely fatal to healthy adults.
Seek medical attention if the bite is deep, bleeds excessively, shows signs of infection, or if you are unsure of the lizard species. A medical professional can assess for broken teeth or debris and determine if a tetanus shot is needed. Seek immediate care if the bite is from a suspected venomous lizard.
Preventing Bites
To prevent bites from wild lizards, observe them respectfully from a distance. Avoid handling them unless absolutely necessary, such as for relocation by a trained professional. Cornering or provoking a lizard can trigger a defensive bite.
Teach children to appreciate lizards from afar, emphasizing that they should not attempt to touch or catch them. Reduce close encounters by removing potential hiding spots like brush piles and debris around your home. Sealing entry points can also prevent lizards from coming indoors.
