Get rid of chipmunks - how?

Take away the reasons they hang around first, otherwise nothing else sticks. Bird feeders are the big one, the seed that drops underneath is basically a buffet. Clear wood piles and rock piles near the house, and keep mulch and dense ground cover pulled back from the foundation so they've nowhere to tunnel unseen. After that, live traps baited with peanut butter or sunflower seeds work well. Check your local rules on relocating wildlife before you drive one off somewhere, some places don't allow it. For bulbs, a layer of hardware cloth over the bed stops the digging.
