I love lizards, these domestic lizards (Gecko species) is 100% non-venomous and harmless. I've been bitten by this thing 3 times, (treatment was wash the "micro wound" with anti-bect soap leave it open) because it's my hobby to catch these lizards and then I take SELFIE with lizard for facebook
Why do you want to kill a harmless creature? A wasp/bee/hornet is the real danger and if it bites you while driving, may cause an accident :o Lizard doesn't bite it will run for safety as it spots you.
