Whose eating the fruit?
Somebody is eating the fruit. I think it’s rodents eating the grapefruit and pumpkin, when you make it easy for the animals/wildlife the next step is entry into your home. I tell everybody, it is extremely important to pick up the fruit that has fallen. No sense feeding any unwanted pest from the neighborhood. Unless of course that is your idea. I know birds will also eat the fruit but uninvited pests are sure to show up.
Oranges, lemons, limes and left over pumpkins are open season for any animal or wildlife. Rodents are prolific breeders and require a lot of food to raise their young. Essential to the control of rodents, eliminate harborage or shelter, reduce water and eliminate food sources. If you can control these factors the rodent population should be controlled.
