Guava and fruit fly:

One of the biggest enemies of guava fruit is the fruit fly. It has an ovipositor which is used to lay eggs inside the fruit and within a couple of days, maggots are formed.  If these fruits are eaten mistakenly, they will not affect the stomach and will be digested like normal meat.

Try to separate the damaged fruits from the healthy ones and fruits that have fallen on the ground should be buried properly by digging a hole in the ground so that more larvae do not come out and spoil the whole fruit of the tree. Spray Diptrix to prevent further attack of the fruit fly.

Another method is to take vinegar (try apple cider vinegar), mix it with a little unscented dishwashing liquid and put it in a plastic container with a hole in the lid and tie it to the tree.  The fly will mistakenly consider it as a fruit and will lay an egg inside it.

When buying guavas, do not buy overripe guavas and those with black spots may contain maggots. 

However, this plant has proved to be a pest many times.  In the forests of Brazil, especially on the island of Hawaii, the strawberry guava species has spread so much that it has consumed the food and water of many other plants and put about a hundred species of plants in danger of extinction.
