Guava keeps about 2–4 days in the fridge at 40°F (4°C) or below, counting from the day you bought it.

| Freezer | Not recommended |
About 2–4 days at 40°F (4°C) or below, according to USDA FoodKeeper v128. That window runs from the day you bought it — FoodKeeper publishes no separate after-opening figure for this one.
Guava is shelf-stable at room temperature: cool, dry pantry, or refrigerate at 40°F (4°C) or below to keep it longer. Refrigerating it mainly preserves quality rather than safety.
Look for: Mould or fuzzy spots; Mushy, collapsed, or leaking areas; A fermented or alcohol-like smell; Slimy skin. Never taste something to test it — when in doubt, throw it out.
USDA FoodKeeper v128 does not recommend freezing Guava — it survives but the texture or quality suffers badly.
