Vintage mole trap.
This is undoubtedly one of the least favorite topics about gardening of which hardly anyone can give a sure and definite solution: getting rid of garden varmints. Poison and traps (inhumane or natural types) or keeping a cat all pop up repeatedly in the various strategies, but the end result is still the same - kill or be rid of them one time and another comes to take its place. Compromise between a gardener and his enemies is like conceding defeat because let's be real here - who in their right mind works under the hot sun only to have their efforts undermined by some beady-eyed critter?
My father-in-law gave us both a spring-release mole trap and a young mole plant in the event we encountered problems; I hope we never need to use them. As for mice or voles (not sure which) I'm taking a defensive approach and transplanting my zucchinis in these wire cages. They're made from low-gauge chicken wire and take a bit of patience cutting and fasteninng together, but I'm hoping that it'll be enough to deter the rodents from eating the roots like last year.
