I’m running an experiment this summer on our grape arbor. Using our CritterCam, I’ve photographed both squirrels and rats munching on grapes. I decided to see if either paper bags or plastic clamshell containers would deter the daily and nightly mammalian fruit buffet. Preliminary results:
- Clamshells don’t work. The fruit fermented, and not in a nice way.
- Paper bags seem to work, but probably only because I left a lot of the fruit exposed in the hopes that they would eat that first and leave the bagged fruit alone. It’s also hard to tell when the fruit is ripe when it’s in a paper bag.
I’m thinking the long term answer is to make custom fruit cages out of hardware cloth. If the grapes were neatly tended on a vine it would be much easier to net them. Netting is not an option on our arbor.
Look carefully in this image and you can see one of the “perps” reaching out to grab a tasty grape:
Have you tackled the mammalian grape buffet issue? How did you deal with it?
