We have been harvesting the concord grapes and my little rat proofs have worked. If you try it, I have a couple of observations.
One, simply having these strange objects in the vines will decrease rat activity. It won’t stop the little brats, but there will be less damage. Two, a trick I learned over the past week is that if some bunches ripen and you take then out, re-use the rat proof, and the moving about of these containers will also dismay the rats. Every day that I made such changes, the activity of rats decreased markedly the following night, and then increased again the night after. Last of all, we were right to say that some grapes might ‘cook’ in the plastic containers– but this only affected grape clusters out in the full sun. All of this said– we have four baskets of grapes and I plan to initiate processing tomorrow to freeze up the makings for a passel of grape pies for fall and winter!
