I wouldn't say a wasp that died in a fig was exploited intentionally by any human, at least, unless the wasps are introduced to figs in order for them to pollinate them. If the absence of action also is considered exploitation, then eating fruit from a tree that a rat has died under could be considered exploitation of animals by that criteria.
Yes, this is a bit of a reductio ad absurdum, but a dead wasp in a fig is already a bit down that road. There is certainly a difference between drinking milk from a cow and a (likely) accidentally dead wasp in a fig.
If you are out in the woods and eat the fruit of a tree that an animal died under and fertilised, that’s fine. It probably also doesn’t extend to animals that were dead long enough to turn into oil.
