Just make sure there are no pesticides being used in your area!! otherwise.. yes of course it is safe
When I had lizards, I used to run around all the time in the field across from the house, except... I don't use butterfly nets I use my hands
I bet from a passer-by's perspective I probably looked pretty funny stalking around a field... creeping up and pouncing on what appears from a distance to be nothing... lol!
