Even the great hunter Roy Spim knew this...

Voice: Now more than ever, they must rely on the skills they have learnt from a lifetime's hunting. (tense music, as they worm their way forward) Hank gauges the wind. (shot of Hank doing complicated wind gauging biz.) Roy examines the mosquito's spoor. (shot of Roy examining the ground intently) Then ... (Roy fires a bazooka. Hank fires off a machine gun; a series of almighty explosions in the small patch of field; the gunfire stops and the smoke begins to clear) It's a success. The mosquito now is dead. (Hank and Roy approach the scorched and blackened patch in the field) But Roy must make sure. (Roy points machine gun at head of mosquito and fires off another few rounds)
Roy: There's nothing more dangerous than a wounded mosquito.
