This trap worked perfectly when it was placed on a hard surface like cement. I sprinkled sunflower seeds at the two entrances and created a trail of sunflower seeds up to the center of the trap where I placed a lot more. This trap worked perfectly, and the chipmunks were easily caught. I then drove the chipmunk to his new home and released him into a woods far away. All the springs and doors worked perfectly. If you place the trap on the ground, the chipmunk will go under the trap to eat the seeds. The trap must be placed on cement, a board, or firm cardboard. This will prevent the chipmunk from going under the trap. I am very happy I bought this trap. I wish I had bought it years ago.

Great chipmunk trap! We have rehomed over 100 chipmunks in the last two years. Used birdseed to set the trap. Sometimes caught two at a time!
