With pomegranate season comes the fight to keep rats, squirrels, leaffooted bugs and birds away from the crop. I've used BirdBlock, bright lighting, and baiting with limited success. This year I went hardcore and stapled together some metal screen pouches. This is just the cheap and ubiquitous metal screen that comes in rolls at the hardware store. The screen is cut into squares large enough to fold over to make a pouch. The edges are then stapled together with a standard office stapler. I hope this solves the problem once and for all.
It's been over a week now and so far, so good. One very aggressive critter got frustrated and tried to rip through a pouch to no avail. It knocked the pom, pouch and all, to the ground where it continued to try gnawing away to still no avail. Yes, I had to harvest that one, but it was a whole fruit that was still edible and great in a salad.
