Why Do Lizards Bite? Like any pest, a lizard will bite as a means of self-defense when it feels threatened. Most bites occur when people try to catch the reptiles in their hands to remove them from homes or yards. This approach can be dangerous, as the lizard will likely attack. Though most lizards have small teeth, they can easily pierce the skin. Lizard Bite Safety Since lizards do bite on occasion, residents should always take caution when attempting to capture the pests. There are safer ways to trap them than by using bare hands, such as placing a flower pot or other container over them and then sliding a piece of cardboard underneath to keep the lizard confined. When lizards do bite, thoroughly clean the wound and seek medical assistance. Though most are nonvenomous, there are some species that can cause serious reactions in humans. All reptiles can also transfer Salmonella through contaminated waste, scratches, and bites. Prevention and Control Lizards are not typically aggressive, but their presence in homes and around yards can be a nuisance. The most effective management begins with sanitation and yard maintenance. Lizards prefer hiding around properties that provide plenty of coverage, from lawn equipment and sheds to brush piles and excess debris. Eliminate the possibility of lizard bites by removing these areas of shelter. When the reptiles persist, trust the professionals at Critter Control to safely handle even the most agile of lizards.
