Chipmunk damage

I am still relatively new to gardening, and permaculture. This year is the first year my strawberries have really been growing well, and would be harvestable. Unfortunately, various chipmunks, squirrels and birds were eating them as they ripened. I put up netting initially, but they crawled under that, so i built a wood and wire enclosure to surround it. That has kept out the birds and squirrels, but the chipmunks just burrowed under and now have free reign. I have lots of hawks, owls and large snakes in the area but they apparently have decided they are too good to eat chipmunks. I would greatly enjoy sitting outside their burrow with a BB gun but i imagine my neighbors frown on that. The only two options i can come up with are sulfur smoke bombs, and snap traps. Has anyone else successfully dealt with these pests?

oh boy!  many animals are attracted to red colors, not so attracted to yellow.
