Hey I find this very interesting. I just received a '10 female lesser from RCReptiles and I've had her for 2 days. I'm leaving her alone for an entire week before I handle her, but I stuck my hand in the tank to adjust the hide and she immediately struck at me (this happened both times I tried). I know this is probably due to the fact that she's only 4 weeks old, shes in a new habitat, and she's probably stressed. But my point is I find it interesting that you have a lesser and that this technique does not work for you. I'm nervous to try it because of your experience. Please let me know what you think.
Thanks in advance
A 4 week old lesser would not hurt you even if it clamped on and didn't let go. I'm sure it's just a defensive strike and nothing to worry about. Neonates are known for being a bit nippy.
