You can flush the wounds with diluted betadyne.
Also, which antibiotic are you using?
The one that is bubbling... are you sure there isn’t another bot down deeper in the hole. Some holes have multiple larvae in them. The first bot I ever saw was bubbling. It was on the shoulder. I had no idea what it was until I did research. Then I about freaked out.
I have to assume it is another bot because if there is a perforating wound to the chest she probably won’t survive. I can’t imagine that a bot would do that.
