If you have grey squirrels visiting your garden, and they can access the strawberries, the point will soon arrive when you don't get a single one for yourself. They would strip my parents strawberry bed. So my parents built a rigid wooden box with chickenwire panels to protect them. The squirrels would jump on the chickenwire until it bent down, then stick their hands through the holes and grab the strawberries. But at least they couldn't reach them all. Once they learned to burrow under the box, my parents gave up growing strawberries.
