Geckos can bite. Biting usually occurs when someone is frightened or angry. However, because the gecko has tiny teeth, it basically does not cause much harm to the human body. However, bleeding may occasionally occur from biting. Unless you are a very familiar gecko, don't let strangers do it casually. The gecko is generally quiet in the hand and will become nervous unless there is a sound or violent movement.

What to do if a gecko bites someone:

It doesn’t matter if the gecko bites someone and bleeds. At this time, squeeze out the blood near the wound first, and then wash it with soapy water. Apply alcohol or iodophor to the wound to disinfect it to avoid infection. Pay attention to observe and protect the wound, and do not let dry wounds come into contact with water.
