Squirrels

Wire mesh is the best you can do until the bulbs are through next spring, the only alternative is poisoning or shooting. I have the opposite problem, squirrels planting walnuts in the borders and pots, industrious little sods.

Put out food for them. It seems counter-intuitive, but, sometimes you have to work with what you've got. We have a mill pond at the bottom of our garden, many rats live around it. Some ventured into the house. We employed a pest control company who suggested we put bird feeders near where the rats live to encourage them to stay away from the house. It has worked a treat.

I only had a few bulb pots but I gathered them together and put the grill shelf from the BBQ across them till the bulbs were through it seemed to work.
