Techniques for eyestalk ablation include:

• Pinching the eyestalk, usually half to two-thirds down the eyestalk. This method may leave an open wound.
• Slitting one eye with a razor blade, then crushing the eyestalk, with thumb and index fingernail, beginning one-half to two-thirds down the eyestalk and moving distally until the contents of eyes have been removed. This method, sometimes called enucleation, leaves behind the transparent exoskeleton so that clotting of haemolymph, and closure of the wound, may occur more rapidly.
• Cauterizing through the eyestalk with either an electrocautery device or an instrument such as a red-hot wire or forceps. If performed correctly, this method closes the wound and allows scar tissue to form more readily. A variation of this technique is to use scissors or a sharp blade to sever the eyestalk, and then to cauterize the wound.
• Ligation by tying off the eyestalk tightly with surgical or other thread. This method also has the advantage of immediate wound closure.
