Protecting fruit from birds/squirrels

Resorted to two fruit cages but still the bugs get in
Environmesh for the brassicas and carrots.
Surrounded the whole garden with chicken wire to keep rabbits out.
Squirrels bit their way in through the plastic net of the fruit cages so had to put a foot of wire netting around the bottom edge.
Squirrels aren't much of a problem now, they don't touch the sweetcorn or courgettes/pumpkins but they do dig holes in the lawn to bury nextdoor's hazelnuts
