Then instead of "tapping her", just offer something soft that smells nothing like her food- it can be your worn clothing if you like- but either way, that often "changes the channel" sufficiently- it's just about letting them know that it's not food coming their way. You can also use a cardboard tube, that's softer than a hook, & she won't catch her teeth on it either. Most anything will work to signal a snake this way.
