Sow bugs get more than half my crop of strawberries every year. We've tried putting down wood planks for them to hide under but they still nibble on almost every berry.

Sowbugs are the ones that doesn't roll up in a tight ball. They like to hide under litter, prefering the humid conditions. Damages to plants are hardly noticeable - mainly seedlings. They tend to be more common when you add wood mulch or letting nature build up leaf litter in woodland gardens. They also are found in wood piles and weedy spots. They are also more of a northern species than pillbugs.
