To track red blight spread patterns effectively, position yourself near grazing grounds when infected aptonoth first appear - they'll display a subtle red glow around their necks about 3 seconds before showing aggressive behavior. The transmission timing follows a specific sequence: once the first monster is infected, nearby herbivores within 15 meters will show symptoms roughly 45 seconds later, similar to how frenzy virus spreads but much faster. Keep an eye on water sources, as contaminated areas pulse with a faint crimson mist every 30 seconds which can affect any monster drinking there.

When tracking infection zones, the optimal distance is about 20 meters from suspected carriers since they'll charge more aggressively at closer range. The afflicted monsters cycle through behavior patterns starting with mild aggression at 2 minutes post-infection, followed by severe aggression at 4 minutes, and finally complete debilitation at 6 minutes. During the severe phase, watch for their characteristic head-swaying animation which telegraphs an area-wide roar that can spread infection in a 25-meter radius.

For control measures, applying nulberries takes exactly 2.5 seconds and creates a 10-meter cleansing zone that lasts 60 seconds, really useful for creating safe corridors through infected areas. Resistance gear needs at least level 2 to prevent initial infection but level 3 is required to maintain immunity during peak outbreak phases when environmental contamination rates double every 3 minutes. Maybe interesting - if you time your nulberry application right as an infected monster begins its stagger animation, you can prevent the spread to nearby monsters within a larger 15-meter radius.
