I believe I have a mice or chipmunk issue with my strawberrires.
I get up evey morning and find 3 or 4 pre-ripened strawberries devoured.
Is there anything I can do to repel them?
Not really. Plant more strawberries so you have plenty to share or enclose the bed in a hardware cloth box both below and above the soil. Bird netting isn't small enough to keep out varmints like chipmunks.
