I've had a vegetable garden for 15 years, but mid-summer last year the chipmunks invaded. I have a 6' fence for the deer. Railroad ties and chicken wire around the bottom for the rabbits etc. BUT THE #@@#@# chipmunks. 4 of them made homes under the railroad ties and I think others would just visit for dinner. If they would only just eat one or two pieces -- but they take bites out of everything. they ruined about a quarter of my crop last year. We had enough for dinner every night but I couldn't freeze/save anything.
I saw one running around the empty garden this morning. THEIR BACK. I used to think they were cute but it is now a major problem.
