They sound good, have seen those offered for sale (I look lots of places online and off). I hope they come back next year for you. Chipmunks like almost anything, little buggers. I have to cover everything I don't want them in with chicken wire which keeps them out. Wouldn't do any good if the strawberries grew through it though. Usually that's what I want, the plant to poke through and hide the wire which keeps the squirrels from digging up the young plants and just plain digging to hide something and go back for it later, double diggers, little buggers. I put rocks, sharp ones the best, I've dug up in the yard on the surface too which helps and also keeps moisture in. Usually one or the other, not both.
But I can't quite figure out what would be best for a strawberry bed to keep the critters out. Don't forget the night scavengers, too.
Its in a courtyard scenario where the plants are, so only one chipmunk who visits[been coming for years], nothing else comes to that side of the house, but a young porcupine last fall kept coming toward the door, would shoo him off finally got the hint was not going to be a pet. Saw him a couple times this spring waddle across but has since moved on. Spring will bring it around again however just to say "am back".
Gray squirrels stay out in the field or more wooded area where the acorns are. No reds which is good!
Few Deer stay up in the field with the turkey population. Nice to watch. Moms have been showing the youth where the winter “feeders” [me] are. Had a doe with triplets not long ago.
Note am not ready to use the “winter” word yet! ;(
